Description
This is a recording of the open-loop output coupling filter with knob curving as described here and here. Sequence length is 2, and both LFSRs are enabled at the same pitch setting.

Description
A ~55 Hz VCO into the FM CV input with maximum FM depth. The length knob is adjsuted. I think the ES-8 may be acting up a little bit, though.

Description
A 2.7 Hz clock is driving the prometheus via the external clock input. The output is used to control a VCA, which is attenuating a fixed-frequency triangle wave. The prometheus filter cutoff knob is adjusted to change the decay rate.

Description
Rev00 and rev01 coupling into frames output. Frames is routed to rev01 v/oct. Starts at 0 V, then turned all the way up to max. Then messing with rev00 frequency. What's happening here is that it seems a substantial amount of rev00 and rev01 signal is coupling through the power supply into the output from frames. There is an additional issue with the frames dac never outputing < 0.5 V, resulting in the vca gain never exceeding ~ -15 dB. I'm seeing something like 200 mVpp of noise in the output even at such low gain.

Description
Demonstration of length-locking and "polyphony" functions on prometheus II now that I have the switch in the multifunction encoder working. In this recording, the length knob is positioned such that noise causes rapid changes the the configured length. Enabling length locking stops the module from updating on input from the length knob and CV inputs, allowing more precise configuration control.
