WoodStepper is a sequencer/sampler having both audio and midi out. The audio input sources can be the track audio, sampled audio or the built-in VCO. It consists of 4 independent 8-steps sequencers which can be linked to a 16, 24 or 32 steps
So WoodStepper can be used as a 4-track looper/sampler.
Each step can also send 4 midi messages (note on, CC, …) to 2 midi channels. The audio part for each sequencer has a pitch (down) shifter, (Moog lowpass) filter with ASR envelope, saturator, amplitude ASR envelope and delay line which can all be set independently per step. More Info »
The VCO notes can be set by midi input and WoodStepper has a function to limit the notes produced by VCO + pitch shifters to a specified key and interval scale. The app can be used stand-alone (device audio input and output) or as a plugin in a DAW. In this case it has to be inserted in an audio track and not in an instrument track as WoodStepper is still an audio effects plugin with additional midi input and output.
