MultiSolo

Getting Started

Everything you need to go from download to playing your first ensemble.

Requirements

  • macOS 11 Big Sur or later (Apple Silicon only)
  • A DAW that supports AU or VST3 plugins — or use the standalone app
  • One or more VST3 or AU virtual instruments installed on your system
  • An MPE MIDI controller (recommended — designed for expressive controllers like the Linnstrument or Seaboard, but standard MIDI keyboards work too)

Sign Up & Download

  1. Create an account to join the alpha
  2. Check your email for a confirmation link, then log in
  3. Go to your Dashboard to copy your license key and download the installer

Install

  1. Open the downloaded .pkg file and follow the installer
  2. If macOS shows a security warning, go to System Settings → Privacy & Security and click "Open Anyway"
  3. The installer places files in these locations:
/Library/Audio/Plug-Ins/Components/MultiSolo.component/Library/Audio/Plug-Ins/VST3/MultiSolo.vst3/Applications/MultiSolo.app/Library/MultiSolo/Presets/

First Launch

  1. Open MultiSolo.app from Applications, or load MultiSolo as a plugin in your DAW
  2. When prompted, paste the license key from your Dashboard
  3. Click the preset name at the top and select a factory preset — Soliste String Quartet is a great starting point
  4. Connect your MIDI controller and play — each note range is routed to a different instrument

Loading Your Own Instruments

  1. Click a slot label (e.g. "Slot 1") and choose Load Plugin to browse your installed AU/VST3 instruments
  2. Set the note range for each slot — notes outside the range are ignored, so instruments don't overlap
  3. Adjust the max voices per slot to control polyphony (fewer voices = lighter CPU load)
  4. Use Save Preset to store your setup for later

Tips

  • MPE controllers: MultiSolo works with MPE-capable controllers like the Linnstrument or Seaboard. Enable MPE mode in your controller's settings for per-note expression.
  • Round-robin vs. note-range routing: Note-range mode splits the keyboard so each slot covers a specific range. Round-robin distributes notes evenly across all slots — great for layering the same instrument with different articulations.
  • Saving presets: User presets are stored in ~/Library/Application Support/MultiSolo/Presets/ and persist across updates.
