People say you should talk to machines. I believe that, just as I believe they also like Music.

Description
Working on wave sounds and a drone for most high honors. Ultimately this will want multiple prometheus II units operating independently. At present the rev01 prototype is in a configuration that consumes excessive power, so the rev00 isn't even plugged in.

Description
Someday I hope to have a working audio signal path that isn't broken. Anyway, there is a sine way driving the FM input, and an LFO driving the glitch input. Sometimes the LFO triggers multiple times due to audio errors. The LFO also goes through a probability gate into an envelope generator, which controls filter cutoff.

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 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
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
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
Rev 00 and Rev 01 providing a couple different drones. Not much else. Real-time priority might have helped a little with audio issues, but not all the way.
