Power

The Poly's universal power supply runs virtually anywhere; 100 - 240 V AC, 50-60 Hz.

All Polys are shipped with Euro adaptor plugs. Customers in the UK and Australia who buy direct will need to get an AC adaptor locally. If you buy from a store, the cables/adaptors will be included.

Editors

The Poly Rack comes with a free Mac/PC stand-alone editor - details here. The editor can be purchased for the keyboard.

4 Banks of 128 Programs for 512 total Programs; 3 banks of 128 Combos (384)- dump to/from MIDI

The internal controllers and DSP chips can be reprogrammed via MIDI, for easy feature additions

The following specs are for one of the four voices, so multiply everything times 4:

.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 words x 12 bits), and 32 user-loadable (via MIDI) Wavetables (128 words 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 Curtis 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 for a true stereo signal path.

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

16 x 4 Analog-style sequencer - syncs with MIDI

Extensive Modulation capabilities, including audio-range modulation. Bipolar (+/-) modulation.
