A lovely PD patch ported to Organelle with aim to make simple and add FX. Delay in particular.
Key 60 (low C) toggled octave mode on and off for discordant or not stuff.
Key 61 on Delay screen selects Left Delay, and key 63 the Right Delay so you can increase stereo effect (any non-used key puts you back to changing both).
Far end key 83 is Reverb Freeze. Again.
