- headphones out (1)

- aux out (4-5)

- pedal CV control (6)

- pedalswitch input (7)

OSCILLATORS 21 voices polyphonic machine .
A standard patch is composed by up to six Voices, each of which uses a digital oscillator playing one of 16-bit resolution 141 waves - up to three Programs can be combined into a performance Preset. The wavetable is organized in various instruments family: String, Brass, Bass, Breath, Tuned Percussion, Percussion, Transwave, Waveform, Inharmonic and Multiwave. From previous VFX, SD it adds two new families DRUM with 32 new samples
NOTE: very rare VFX-SD II also adds the 1mb piano (like in SD1) and a better OS more stable

TRANSWAVE VFX synthesizers are very famous for this special waves that can be played from any starting point , moving through the wavetable as the note is held — the waveform is changing progressively between many small waveforms (100) and the result is that you can create complex texture and variations. The VFX SD contains 17 transwave "waves" to play with.

ENVELOPE 3 EG first is hardwired to pitch modulation, the second to the filter and the third to amplitude.

Effect, filter, sequencer and memory

FILTER two digital filters in series:

- Filter 1 can be used as a 2- or 3-pole lowpass filter

- Filter 2 as a 1- and 2-pole hipass or lowpass filter - in combination also as a bandpass.

EFFECTS 15 full-editable algorithms including: Large Hall Reverb, Small Hall Reverb, Room Reverb 1 and 2, Dynamic Reverb, 8-voice Chorus, Chorus and Reverb 1 - 2, Flanger and Reverb 1 and 2, Delay and Reverb 1 and 2, Flanger and Delay and Reverb 1 and 2, LESLIE Speaker and Delay

SEQUENCER 24-track sequencer with 25,000 note capacity expandable to 75,000, and it holds up to 60 sequences and songs. There is quantization (96 ppqn), real or step time input and auto-punch in/out.
