Effect Automation

The rotary knobs of all audio effects can be automated. The Band Effect, the Convolutor's Delay knob and the Guitar Amp's Cntr/Edge and Output knobs can't be automated. The Compressor's Autogain button has no effect if the Threshold, Ratio or Gain knobs are automated. The Arpeggiator (MIDI effect) can't be automated either.

'Delay' type knobs may cause glitches while turning. It's best to move these knobs in a quiet part. This applies to the following knobs:

  • Chorus, Doubler, Echo, Flanger: Delay.
  • Master Limiter: Ahead.
  • Reverb: Predelay.
  • Pseudo Stereo: Color (Comb mode only)
  • Vibrato: all.
  • Guitar Amp: Cntr/Edge (not a 'delay type knob', but it does glitch)
  • Phaser: Notches (not a 'delay type knob', but it does glitch)


VST and AU plugins can be automated too. To pop up the effect's Automation Editor you should click the Automation button in the bottom right corner of the main window first, and then click the right hand side of the effect window (the area where the Bypass and OK buttons are). Right clicking this area also works.

VST3 plugin controls can have an 'Show automation editor' option in their rightclick menu. This is the case if the plugin supports this VST3 feature.

Knob movements can be recorded while the transport is running, just like MultitrackStudio's own faders and rotary knobs. VST2 plugins need to be built with SDK 2.1 or higher for this to work.

A multiple output VST/AU plugin's output mixer can be automated too.
