I am fairly new to PD and I'm creating a monophonic synthesizer to be controlled by MIDI keyboard.
MIDI in is not a problem and I've set 'note on' messages to trigger an ADSR which envelopes the output from my bank of oscillators.
The real problem is that it doesn't behave as a mono synth should because it has no memory of which notes are being held. E.g. If I play a C and hold it down then play a D and release it, the synth should go back to playing the C. But in my setup, the audio just stops because there is no trigger to the ADSR.
How have people got round this problem before and does anyone have a simple patch that can demonstrate 'correct' mono synth behaviour?
Any help appreciated,
Al
