Melody Sauce 3 User Guide
Version 3.1 | evabeat.com
1. Introduction
What is Melody Sauce 3?
Melody Sauce 3 (MS3) is a melody and chord progression generator plugin for Mac and Windows, compatible with all major DAWs. It is a complete rebuild of Melody Sauce 2, designed to boost your music making with an unlimited supply of high-quality musical ideas that you can control in detail.
Where previous versions focused only on quick melodic inspiration, MS3 adds a complete chord progression engine, a piano roll editor, MIDI import with automatic key and chord detection, a redesigned interface, and many other features that put you front and centre of the creative process. Version 3.1 adds plugin hosting, so you can play your melodies, chords and bass through your own instruments directly inside MS3.

4. Core Concepts
Genre & Style
Genre and Style work as a two-level preset system. Selecting a Genre opens the style menu, showing the Styles available for that genre. Styles are combinations of settings across the plugin, designed to generate melodies in a particular style. Each style also generates its own chord progressions to fit that style, and loading a style adjusts all the plugin settings, including sounds and chord voicing.
Style presets do not mean the output is pre-programmed — melodies are unique and generated from scratch every time.
To keep your current chord progression, sounds or voicing when you change style, switch on Chord Lock, the Sound Locks or Voicing Lock (see Locks).
Choose Free for a genre-neutral starting point with no styles and manual control over all parameters.
Key & Scale
All output is locked to a musical key, shown as major/minor pairs. With Key Lock off, MS3 randomly selects a key each time. Selecting a key or enabling Key Lock fixes it for all subsequent generations.
Chord Progressions
Every pad click generates a matched chord progression alongside the melody. Chord progressions appear as blue regions in the piano roll. Drag edges to change length, right-click to split/delete, click to open the chord selection menu. Use the Voicing control in the Chord layer to change how the chords are voiced (see Chord Layer & Voicings).
Locks
Locks keep parts of your idea fixed while you generate new ones or change style. All lock icons show a grey open padlock when off and a green padlock when on. A lock only stops MS3 from replacing the locked item — you can still edit locked chords, voicings and keys yourself.
| Key Lock | Keeps the key for all generated melodies. Switched on automatically when you select a key or import MIDI chords. |
| Chord Lock | Keeps your current chord progression: new melodies use the same chords and no new chord progressions are generated. When using styles, the chord progressions designed for that style won’t be used — your chords are kept when you change style. Switched on automatically when you change a chord or import MIDI chords. |
| Melody Lock (Phrase Lock) | Locks the whole melody, or just selected phrases. With the whole melody locked, clicking a pad generates new chords for it. With phrases locked, pads generate a new melody around the locked notes. Turns off when you change style or genre. |
| Voicing Lock | Keeps your chord voicing when you change style, instead of loading the voicing the style was designed to use. |
| Sound Locks | One per layer. Keeps that layer’s sound, octave and effects when you change style, instead of loading the sound the style was designed to use. |
The Melody Bank
Every melody is stored as a clip in the Melody Bank. Clips can be favourited or deleted. Use Add New Clip before generating to avoid overwriting. Your favourites are shared across all your projects.
5. Generating Your First Melody

Load Melody Sauce 3 on an instrument track in your DAW, then follow the numbered steps:
- Set your Key — Pick a key, or leave Key Lock off for a random key.
- Choose a Genre — Click a genre to open its style menu, or select Free.
- Select a Style — Choose from the style menu, or hit Dice to randomly select a style across any genre.
- Click a Pad — Mood (Light/Dark) vs Complexity (Simple/Complex). Only compatible pads are available.
- Audition — Melodies play automatically. Use the clip’s play/pause button, the Play button in the top bar, or your DAW transport.
- Edit — Tweak notes in the piano roll, try different sounds, voicings and plugins, or adjust controls.
- Export to DAW (audio) — Click Audio to render the clip, then drag the WAV into your DAW.
- Export to DAW (MIDI) — Drag the clip’s drag icon onto a MIDI track to export the melody, chord and bass MIDI.
Iterate by trying different pads, styles or genres. To keep a melody, favourite it or click + (Add New Clip) before generating the next one.

Chord Voicings
Voicings change the feel of your chords — the same chord progression can sound sparse and tight, or wide and lush, depending on how its notes are arranged. MS3 includes over 100 voicings, from simple 2-note chords and tight stacks to wide-open spreads.
Click the Voicing selector to open the voicing menu. Each option has a short description of its character, for example “(piano, deep)” or “(wide/EDM)”.

- Lower — the lowest notes of the chord: Single, Octaves Hi, Octaves Lo, Fifth, Triad or None. Clicking a Lower option applies it straight away and keeps the menu open, so you can hear the difference.
- Upper Essentials — the core upper voicings: Adaptive, Triad, 1st, 2nd and 3rd inversion, and Fifth.
- Upper Shapes — more voicing shapes, from sparse 2-note shapes (e.g. 1+3) to wide spreads and dense stacks (e.g. 3+1+3, 5+1+3+5). Clicking an Upper option applies it and closes the menu.
Use the arrows either side of the Voicing selector to step through voicings. The voicing applies to every chord in the clip. Octaves Lo · Adaptive is the plugin’s standard chord voicing.
Each style loads the voicing it was designed to use. To keep your voicing when you change style, click the Voicing Lock padlock next to the Voicing label, or select “Don’t load style voicings (lock voicing)” in the Settings menu. Click the padlock again (or deselect the menu option) to unlock.

| Volume | Bass layer output level. |
6.9 Sounds, Scenes & Sound Locks
Each layer (Melody, Chord and Bass) has its own sound menu. In the Source column, choose Internal Sounds for MS3’s own sounds, Plugins to play that layer through one of your own instrument plugins (see Plugin Hosting), or Scenes to save or load a sound combination.

| Search | Type in the search box at the top of the sound menu to find sounds and plugins across all categories. |
| Plugins | Lists your scanned plugins by manufacturer, then plugin, with the format shown after each name, e.g. “Spire (VST3)”. Select Scan Plugins in the Settings menu first. |
| Scenes › Save scene | Saves your current melody/chord/bass sound combination as a scene, including each layer’s volume, octave and on/off state. |
| Scenes › Load scene | Loads a saved scene by name. |
| Sound Lock | The padlock next to each sound menu keeps that layer’s sound, octave and effects when you change style, instead of loading the sound the style was designed to use. |
6.10 MIDI Settings

| Internal | Default. Plays using MS3’s internal sounds or your hosted plugins. |
| MIDI In | MS3 receives incoming MIDI from your DAW, like a synth — Melody receives MIDI from DAW channel 1, Chords from channel 2, Bass from channel 3. |
| MIDI Out | Sends each layer’s generated MIDI to your DAW on separate channels (Melody 1, Chords 2, Bass 3) so each can be routed independently. Internal sounds are bypassed. Toggle layers to control output. |

7. Plugin Hosting
Using Your Own Plugins Inside MS3
MS3 can host your own instrument plugins, so the melody, chords and bass play straight through them — with no MIDI routing needed. You can load a different plugin on each of the three layers, for example a lead synth on the melody, a piano on the chords and a bass synth on the bass.
- Scan for plugins first: open the Settings menu (gear icon) and select Scan Plugins (see Scanning for Plugins).
- Open the sound menu for the Melody, Chord or Bass layer and choose Plugins. Plugins are listed by manufacturer, or type in the search box to find one.
- Select a plugin to load it on that layer. The layer now plays through your plugin.
- Click the Open Plugin Window button next to the plugin name to open its window and adjust its sound. The window opens in front of MS3.
| Supported formats | VST3 and VST2 (Mac and Windows), and AU (Mac). Plugin hosting is not available in the AU MIDI FX version of MS3. |
| Not supported | DAW stock/built-in instruments (for example Logic’s or Ableton’s own instruments), which are not available as separate plugins. 32-bit plugins are not supported. |
| Effects | MS3’s internal effects (reverb, delay, chorus, wobble) apply to internal sounds only, not to external plugins. Use your plugin’s own effects, or your DAW’s. |
| Saving | Hosted plugins and their settings are saved with your DAW project. Save a scene to reuse a combination of plugins and sounds later. |
| Audio export | Audio export works with hosted plugins as well as internal sounds. |
Using Multi-instrument Plugins
Some plugins can hold several sounds at once, each listening on its own MIDI channel. Examples are Kontakt, Omnisphere and SampleTank. MS3 sends notes to hosted plugins on MIDI channel 1, which matches how these plugins are set up by default.
If a hosted plugin is silent even though MS3 is playing notes, check which MIDI channel the sound is set to. It needs to be set to channel 1 or Omni / Any (meaning all channels):
- Omnisphere: load your sound into Part 1. On the Mixer page, check that Part 1’s MIDI channel is 1 or Any.
- Kontakt: in the instrument’s header, set MIDI Ch to Omni or [A] 1. If you can’t see MIDI Ch, click the camera icon in the header.
Scanning for Plugins
To use third-party VST/AU plugins inside MS3, you’ll need to scan your system first:
- Open MS3 and go to the main Settings menu (gear icon).
- Select Scan Plugins.
- MS3 will search the standard VST3, VST2 and AU plugin folders on your system for installed plugins. Once the scan completes, any compatible plugins found will be available to load and use directly inside MS3.
Run Scan Plugins again whenever you install new plugins — it picks up plugins added since your last scan, and retries any plugins that failed previously. Rescan Plugins scans everything again from scratch, which can take several minutes if you have a lot of plugins installed.
If a plugin doesn’t respond within 30 seconds during the scan, it’s marked as failed and the scan moves on to the next plugin.
Plugin Scan Troubleshooting
A useful first check is whether all your plugins are missing, or just a few:
- No plugins found, or the scan doesn’t finish — this usually means something is stopping the scan itself, such as security software. See the steps below.
- Only a few plugins are missing — this is usually caused by the individual plugins. See Some plugins are missing below.
No plugins found, or the scan doesn’t complete
- Security software, firewalls and antivirus — depending on your security settings, software such as Norton, Bitdefender, McAfee, Windows Defender or Windows SmartScreen can block MS3 from scanning your plugins. Temporarily disable it, or add MS3 and your DAW to its list of allowed/trusted applications, then run Scan Plugins again. On Mac, check any antivirus software you have installed in the same way.
- Restart and scan again — close your DAW, reopen it in a new empty project, load MS3 and run Scan Plugins. If plugins still don’t appear after the scan, remove MS3 from the track and load it again.
- Try a full rescan — select Rescan Plugins to scan all your plugins again from scratch. Allow several minutes for it to finish.
- Windows: run your DAW as administrator — right-click your DAW and select “Run as administrator”, then run the scan again. This can help if Windows permissions are preventing the scan results being saved.
- Check where your plugins are installed — MS3 scans the standard plugin folders (below), so plugins installed in other folders, or in a cloud-synced folder such as OneDrive, won’t be found. Reinstall them to the standard folders, then scan again.
| Mac — VST3 | /Library/Audio/Plug-Ins/VST3/ |
| Mac — VST2 | /Library/Audio/Plug-Ins/VST/ |
| Mac — AU | /Library/Audio/Plug-Ins/Components/ |
| Windows — VST3 | C:\Program Files\Common Files\VST3\ |
| Windows — VST2 | The standard VST2 folders (e.g. C:\Program Files\VSTPlugins\) |
Some plugins are missing
Some plugins load in your DAW but can’t be loaded by another plugin host such as MS3. Common reasons:
- DAW stock plugins — instruments built into your DAW aren’t separate plugins, so they can’t be hosted in MS3.
- Plugins that need activating or show a pop-up — if a plugin shows a licence, authorisation or setup window when it first loads, it may time out during the scan. Open the plugin once in your DAW and complete any activation, then run Scan Plugins again (Scan retries plugins that failed previously).
- “Shell” plugins — some plugins (for example Waves WaveShells) contain many plugins in one file and can be slow to load. They may time out during a scan. Run Scan Plugins again, or try Rescan Plugins.
- Moved, updated or damaged plugins — if a plugin’s files or content have been moved or updated, reinstall it using the manufacturer’s installer or manager (for example Native Access for Native Instruments plugins), then scan again.
- 32-bit plugins — these are not supported.
- Intel-only plugins on Apple Silicon Macs — plugins that haven’t been updated for Apple Silicon can only be loaded when your DAW is running under Rosetta. Check with the plugin manufacturer for a native version.
- Melody Sauce 3 itself — MS3 can’t be loaded inside itself, so it doesn’t appear in the plugin list.
If a plugin still won’t appear, email support@evabeat.com with the plugin name, version and format (VST3, VST2 or AU), your operating system, and your DAW.
8. Working with MIDI & Audio
Exporting MIDI to Your DAW
Drag the Clip Drag icon from the Melody Bank onto a MIDI or instrument track in your DAW. MS3 creates separate MIDI files for the Melody, Chord and Bass layers. Toggle layers on or off before dragging to control exactly what is exported.
You can also select Export MIDI… in the Settings menu to export the current clip as MIDI files (separate Melody, Chord and Bass files) to a folder on your computer.
Exporting Audio
MS3 can render the current clip to WAV audio — a full mix of the melody, chords and bass plus separate stems for each layer. Audio export works with internal sounds and with hosted plugins.
- Select the clip you want to export in the Melody Bank.
- Click the Audio button at the top of the Melody Bank. A progress bar shows while the audio renders.
- When rendering is complete, the button changes to WAV. Drag it into your DAW.
Alternatively, select Export Audio Stems… (wav) in the Settings menu to save the audio files to a folder on your computer.
By default, audio exports are exactly 8 bars long so they loop cleanly in your DAW. To include the reverb/delay and release tail, select Render audio tail in the Settings menu. With the tail on, the exported audio will be longer than 8 bars.
Importing Chord MIDI
To import a chord MIDI file, drag it from your desktop (or file browser) directly into the piano roll area of the plugin. MS3 will detect the key and apply it to the Key setting in the UI. It will also detect the chord progression and apply the chords to the blue chord regions in the piano roll, ready for you to generate a melody to fit. After importing, Chord Lock is enabled automatically to prevent your chords from being overwritten when you click a pad.
MIDI Out Mode
In MIDI Out mode, MS3 outputs its generated MIDI so you can route it to other instruments in your project instead of using its own internal sounds. Each layer is sent on its own MIDI channel — Melody on channel 1, Chords on channel 2 and Bass on channel 3. Toggle the Melody, Chord and Bass layers on/off to control which streams are output.
The exact routing method depends on your DAW. Common approaches include setting the MIDI input of a second instrument track to Melody Sauce 3, or using your DAW’s internal MIDI routing. Consult your DAW documentation for the specific steps.
MIDI In Mode
When MIDI In is selected, MS3 bypasses its own generation engine and receives MIDI from your DAW like a synth plugin. MS3 automatically receives MIDI from your DAW on 3 separate channels:
- Melody layer: MIDI channel 1
- Chords layer: MIDI channel 2
- Bass layer: MIDI channel 3
This means you can drag MS3’s 3 MIDI layers to your DAW to edit them there, then route the 3 MIDI layers back to the same single instance of MS3. To do this, once you’ve dragged MS3’s 3 MIDI layers to 3 MIDI tracks in your DAW, route each of those 3 MIDI tracks out via either MIDI channel 1, 2 or 3 back to MS3. Please refer to your DAW’s documentation on how to set up MIDI out channels in your DAW.
Sound controls remain active (including hosted plugins); all other controls are disabled. To exit this mode, switch MIDI Settings to Internal or MIDI Out.
Multi-channel Audio Output
MS3 outputs audio as 3 stereo pairs so that you can process audio from MS3’s 3 layers separately in your DAW. This includes layers played through hosted plugins.
To set this up in your DAW, set the audio input on 3 audio tracks to receive audio from the separate Melody, Chords and Bass audio outputs provided by MS3. Please refer to your DAW’s documentation on how to set up audio inputs in your DAW.
Playing MS3 Through Multiple Instruments
There are two ways to play MS3’s melody, chords and bass through three different instruments:
1. Plugin Hosting (easiest)
Load your instruments directly inside MS3 using Plugin Hosting. Choose a different plugin in each of the Melody, Chord and Bass sound menus — no MIDI routing is needed, and you can still send each layer to its own audio track using Multi-channel Audio Output.
2. MIDI Out to three instrument tracks
Set MS3’s MIDI Settings to MIDI Out. MS3 sends each layer on its own MIDI channel — Melody on channel 1, Chords on channel 2 and Bass on channel 3.
- Create three instrument tracks in your DAW and load an instrument on each.
- Set the MIDI input of each track to Melody Sauce 3.
- Set the first track to receive MIDI channel 1 (Melody), the second channel 2 (Chords) and the third channel 3 (Bass).
The exact steps depend on your DAW — please refer to your DAW’s documentation on routing MIDI from a plugin to other tracks.
Logic Pro — AU MIDI FX
In Logic Pro, Melody Sauce 3 can be loaded in two ways. The standard approach is to load it as an instrument plugin on a Software Instrument track, where it generates both audio and MIDI internally.
The second approach — exclusive to Logic — is to load the AU MIDI FX version of MS3 into the MIDI FX slot of a Software Instrument track. In this mode MS3 outputs MIDI only (no audio), which is passed directly to the instrument loaded in the same track’s instrument slot. This means you can use MS3 to generate melodies and chord progressions that are played back by any software synth or sampler of your choice, all within a single track.
- Create a new Software Instrument track.
- Click the MIDI FX slot (located above the instrument slot in the channel strip) and select Melody Sauce 3 from the AU MIDI FX category.
- In the instrument slot below, load the synthesiser or sampler you want MS3 to drive.
- MS3 will now send its MIDI output directly to that instrument.
MIDI channels in the MIDI FX version
In the MIDI FX version, MS3 sends each layer on its own MIDI channel:
- Melody: channel 1
- Chords: channel 2
- Bass: channel 3
Most instruments play all channels, so all three layers will play. Multi-instrument plugins such as Kontakt and Omnisphere only play channel 1 by default, so you’ll hear only the melody. You have two options:
- Play all three layers through one sound: set the instrument to respond to all channels. In Kontakt, set MIDI Ch to Omni. In Omnisphere, set Part 1’s MIDI channel to Any.
- Give each layer its own sound: load three sounds into the plugin, set to channels 1, 2 and 3. In Omnisphere, load your melody sound into Part 1, chords into Part 2 and bass into Part 3; these are already on channels 1, 2 and 3 by default. In Kontakt, load three instruments and set their MIDI Ch to [A] 1, 2 and 3.

11. Troubleshooting & FAQ
| Plugin missing in DAW | Rescan plugins in your DAW’s plugin manager. On Mac, check AU or VST3 is installed in the standard system paths. On Windows, confirm the VST3 folder is in your DAW’s scan locations. Security software can also quarantine plugin files — check it hasn’t blocked MS3. |
| My plugins don’t appear in MS3 | Select Scan Plugins in the Settings menu first. See Plugin Scan Troubleshooting. |
| Kontakt, Omnisphere or another multi-instrument plugin is silent inside MS3 | MS3 sends notes to hosted plugins on MIDI channel 1. Make sure your sound is set to channel 1 or Omni / Any. In Omnisphere, load it into Part 1. In Kontakt, set MIDI Ch in the instrument header to Omni. See Using Multi-instrument Plugins. |
| Logic MIDI FX: only the melody plays | The MIDI FX version sends melody, chords and bass on channels 1, 2 and 3. Plugins like Kontakt and Omnisphere only play channel 1 by default. Set the instrument to Omni (Kontakt) or Any (Omnisphere), or load separate sounds on channels 1, 2 and 3. See MIDI channels in the MIDI FX version. |
| Can I host plugins in the MIDI FX version? | No. The MIDI FX version only sends MIDI and doesn’t produce sound. Load MS3 as an instrument and choose Plugins in a sound menu, or keep MS3 in the MIDI FX slot and load your plugin as the track’s instrument. |
| Effects don’t work on my plugin | MS3’s effects apply to internal sounds only. Use the plugin’s own effects or your DAW’s. |
| No sound | Check a clip is loaded, at least one layer is on, Master Volume is up, and your DAW’s audio output is working. In MIDI Out mode, ensure the receiving instrument is set up correctly. If a layer uses a plugin, open the plugin window and check it’s producing sound. |
| Only one MIDI file on drag / can’t drag to Cubase | Use Export MIDI… in the Settings menu. Or export each layer separately: switch off two layers, drag once, then repeat for each remaining layer. |
| Chord Lock turned on automatically | Activates automatically when you edit a chord region or import MIDI chords, to prevent your changes being overwritten. |
| My chords didn’t change when I changed style | Chord Lock is on. Switch it off to load the chord progressions designed for the new style. |
| Melody Lock switched off | Melody Lock turns off when you change style or genre, and when you switch on Chord Lock — the two can’t be used together. |
| Pads greyed out | Not compatible with current style. Click Free to unlock all pads, or try a different style. |
| Pads and Melody Bank have disappeared | The piano roll is expanded. Click the Expand Piano Roll button to return to the normal view. |
| Out of tune with project | Confirm the Key matches your project. Check your DAW’s master tuning and any track transpose settings. |
| MS3 out of sync with DAW | Open the Settings menu and select “Always Sync to DAW”. This makes MS3 follow the DAW playhead position rather than always restarting from bar 1. |
| Standalone use? | MS3 is a plugin and requires a DAW or plugin host. It does not run standalone. |
| How to update | Download the latest installer from evabeat.com or your Plugin Boutique account and run it over the existing installation. |
| Apple Silicon? | Yes. Universal Binary, native on Intel and Apple Silicon Macs. |
FL Studio
MS3 sounds too fast or too high in FL Studio on Mac
Check that the sample rate in FL Studio’s Audio Settings matches your audio device’s Format in Audio MIDI Setup. Open Audio MIDI Setup (Applications → Utilities), click your output device (e.g. MacBook Pro Speakers), and set the sample rate to the same value as FL Studio’s Audio Settings — usually 44100 or 48000 Hz. This affects all sounds in FL Studio, not just MS3.
MS3 loads an old version in FL Studio after updating
After updating, if FL Studio’s Plugin Manager shows Melody Sauce 3 as “ok” but an older version loads when you open the plugin, try this:
- Close FL Studio (and any other DAW).
- Go to your VST3 folder:
- Mac:
/Library/Audio/Plug-Ins/VST3/ - Windows:
C:\Program Files\Common Files\VST3\
- Mac:
- Look for all Melody Sauce 3 VST3 files (e.g.
Melody Sauce 3.vst3). - Delete all of them.
- Reinstall Melody Sauce 3 using the latest installer.
Reopen FL Studio, open Plugin Manager, and click Find installed plugins to do a full rescan.
MS3 only plays a short loop in FL Studio
Because of the way FL Studio handles pattern lengths, create an 8-bar pattern or MIDI region in your arrangement to hear the full output, and make sure “Always Sync to DAW” is deselected in MS3’s Settings menu.
Serial Code Issues
Make sure you’re connected to the internet — an internet connection is required for serial activation.
New orders: Enter your MS3 serial under the “New Licence” tab in the plugin’s licensing window. Check there are no spaces at the beginning or end of the serial when you paste it, then click “Activate”.
Upgrades: Click the “Upgrade” tab, enter your Melody Sauce 1 or 2 serial in the first field, click “Verify”, then enter your MS3 upgrade serial in the second field and click “Activate”. An MS3 Upgrade serial requires a valid Melody Sauce 1 or Melody Sauce 2 serial.
If you still have problems, email support@evabeat.com.
Purchase Issues
We use FastSpring for our checkout. Occasionally its security measures may block an order attempt. Please try an alternative payment method (e.g. a different credit card, PayPal, or Apple Pay), or purchasing from a different browser or device. If you’re still unable to place an order, email support@evabeat.com.
Troubleshooting MS3 on Windows
Windows Controlled Folder Access
If you’re experiencing any issues with files, presets or samples not loading, this is often the cause. Open Windows Security → Virus & Threat Protection → Ransomware Protection → Allow an app through Controlled Folder Access, and add your DAW’s executable file. Restart your DAW and try again.
Install pending Windows updates
Install any pending Windows updates, including graphics driver updates. Outdated graphics drivers in particular can prevent MS3 from operating correctly.
Error 126
- 64-bit check — Make sure you’re running 64-bit Windows and the 64-bit version of your DAW.
- Rescan plugins — Restart your DAW, open a fresh project, and rescan plugins.
- Antivirus / Firewall — Temporarily disable security software, reinstall MS3, then restart your DAW.
- Visual C++ Redistributables — Download and install both x64 and x86 versions of the 2015–2022 redistributable from Microsoft.
- OneDrive — OneDrive’s “Known Folder Move” feature can redirect folders to cloud storage. Pause OneDrive sync, ensure MS3’s install path is local (e.g.
C:\Program Files\VSTPlugins), and check your DAW’s plugin scan path is not cloud-synced. - If none of the above help, contact us — Windows Registry corruption is another known cause.
“No internet connection” during activation (when internet is working)
- Disable any VPN or proxy and try again.
- Check your system date and time are correct.
- Try running your DAW as Administrator.
- If still stuck, contact us — your firewall or ISP may be blocking MS3’s validation server.
DAW freezes when loading MS3
If you have an Nvidia graphics card on Windows 10, open Device Manager, expand Display adapters, right-click your Nvidia GPU and select “Update driver”. If the issue persists, try rolling back to an earlier driver version from the Nvidia website.
Installer fails
- Install all pending Windows updates, restart, then try again.
- Right-click the installer and select “Run as administrator”.
- Temporarily disable antivirus, firewall, and SmartScreen.
- Press Win+R, type
%temp%, delete as many files as you can, then try again. - If still stuck, contact us with your MSI log: open an Administrator command prompt and run
msiexec /i [installer-filename].msi /lv c:\setup.log.
