"Features:
* Four oscillators in total: two analog, two digital
* Analog Oscillator waveshape are Sawtooth, Triangle, Saw-Triangle, and Pulse (with voltage-controlled analog Pulse-Width modulation)
* Digital Oscillators select from 96 wavetables from the Prophet-VS (128 x 12 bits), and 32 user-loadable (via MIDI) Wavetables (128 x 16 bits). The Digital Oscillators get trashy as the frequency gets higher, as with the original VS.
* Hard Sync on the analog oscillators
* FM and Ring Mod on the digital oscillators
* Separate Glide per oscillator, with two glide modes
* Real voltage-controlled analog lowpass filters - not digital recreations. 4-pole/2-pole switchable, fully resonant (in 4-pole mode). There are two separate filters, one for the left channel and one for the right.
* Analog Voltage Controlled Amplifiers (VCA), again one for each channel.
* Dual digital 4-pole Highpass filters (one per channel); place before or after analog electronics.
* Stereo audio inputs; Noise generator
* Envelope Follower and Peak Detect from External Input to use as modulation sources
* External Input can be used to gate envelopes and/or step the Sequencer
* Three snappy ADSR envelopes
* Four LFOs (sync with sequencer and MIDI)
* Dual (left and right channel) tunable feedback loops; modulate frequency and amount
* Delay with 3 taps; each with separate time and amount modulation. Syncs to sequencer/MIDI. Normal feedback and additional feedback path through analog filters
* Distortion! Digital, one for each channel, can be placed before or after analog electronics
* 3 Banks of 128 Programs for 384 total Programs - dump to/from MIDI
* 16 x 4 Analog-style sequencer - syncs with MIDI
* Extensive Modulation capabilities, including audio-range modulation. Bipolar (+/-) modulation."
