One of my favoured things in #modular #sound #synthesisers is the negative envelope and #inverted #VCA. Inverted VCA is a unique technique in modular that no other instruments can provide. Traditional VCA opens up the volume (or filter) when the key is pressed and we can hear the sound. Inverted VCA closes when key is pressed or signal received and we will not hear the sound until we release the key. It's a good #compositional tool for opening the sound for adding other #instruments or #noises.
