This is a simple patch that takes audio in (right channel only) from a stomp box or piezo transducer (or any other signal which you may use to create a percussive noise) and sends signal through the following modules: envelope follower to Trigger module and keyboard module – Trigger cv out to midi note out module gate in – Keyboard module note out to midi note out note in, keyboard trigger out to midi note out gate in.
*Midi is sent out on channel 3*
You can then use this to trigger a sample or synthesised kick / snare / drum of any type
Keyboard module is at C1 but you can tune / change this to suit.
I have made another more complex version that uses ZOIA as the sound source as well being able to layer up the midi control aspects of this patch.
