NUSofting has released Groove Analogizer, an audio controlled drum synthesizer, as freeware.

Similar to a vintage electronic drum tone generator (e.g. Simmons) the percussion sound is triggered by an audio input, not by a MIDI message.

Groove Analogizer features:

• 3 oscillators synth (loads as effect plug-in), triggered and shaped by the audio input in many ways.
• Selection of left, right or left+right input (input can be both mono or stereo).
• Band pass filter (coarse and fine) for selection of frequency range of the audio source to be used for triggering.
• Pre-Listening for monitoring which part of the source is selected as trigger.
• Sensitivity for selection of the loudest triggers filtered by the band pass.
• 128 presets ready to play.

Groove Analogizer is available for Windows PC as freeware.
