Groove Analogizer is an “audio controlled drum synthesizer”, it means that like a vintage electronic drum tone generator (e.g. Simmons) the percussion sound is triggered by an audio input, not by a MIDI message. This also means that you must not load, in the host, Groove Analogizer as a VST instrument, it loads as a VST effect, usually in an insert slot.

But it’s really a synth: the sound of three oscillators is triggered and shaped by the audio input in many ways.Groove Analogizer is an “audio controlled drum synthesizer” or a drum tone generator triggered by an audio input rather than a MIDI message.

Groove Analogizer must load as a VST effect, even though it’s actually a closer to a synth. Sounds of three oscillators are triggered and shaped by your audio in. Here’s how triggering works:

Any sort of percussive (meaning anything with a fast attack and moderate to fast decay / release) sound can be triggered in mono or stereo as a .wav file or VST instrument. Three generators each allow you to select left, right or left+right inputs before a band pass filter defines which frequency range will work as the trigger.

This allows you to create different patterns from a single audio source by separating the hi, mid and low tones. You can also use a Pre-Listening feature to monitor your trigger. The Sensitivity control more precisely selects the loudest triggers so that you can take or leave ghost notes as triggers.

If you want to move beyond the 128 presets, you’re afforded ample control:

• Sound Controls For each generator:
  • Release time: amplitude and pitch envelope time
  • Bending: positive or negative pitch envelope amount
  • Offset : pitch base
  • Timbre: from pure tone to noise, with FM option. New: overtone mode
• Output Controls For each generator:
  • Effect: send to internal stereo delay
  • Pan: stereo image
  • Volume: output level
• Master Controls:
  • FM: global amount
  • Smooth: slope time for all envelopes
  • Delay effect controls
  • Dry: output of the trigger (source audio)
  • Master : output level of all three generators
