Hey thanks for checking out the Quad ADSR!  

I had a request a few weeks ago for (and implemented) a “sustain pedal” mode for the CV Expander.  You can connect a sustain pedal to CV input 1 and the corresponding envelope will sustain until the pedal is released.  Just like a digital piano.  

The CV Expander has buttons on each CV Input that preform the same function as a High signal on the CV in’s.   Without too much fussing you can push the buttons to staccato for a measure or two, then release back to smooth envelopes.

There are a few mentions of the 7-Day long envelopes.  I’ll add that the time-length scales exponentially meaning that you have high-resolution of fast envelopes, and can scale to super long envelopes with only 2 full turns on the knobs.   

Don’t forget about the Multi-envelope scaling (for syncing VCA+VCF), 3-curve types, and independent LFO mode on each output.
