via NIIO analog
The GRAPHIC ENVELOPE consists of 2 separate analog envelopes each derived from stepping thru 8 levels at a shared rate. The envelope can be run as a dual 8 step or a dual 15 step envelope.
Easily create and adjust complex envelope shapes with time based movement that is easily adjustable in a graphic layout.
3 usable time ranges allow for the accurate setting of specific overall envelope times.
Level inputs allow CV or audio to set the level of the envelopes.
2 rate knobs set the envelope length and can be switched between via gate or CV input.
The 2 envelopes can be swapped to the other's output pre- Response via gate or CV input.
The HOLD STEP pauses the envelope while the gate input is high, making a playable and responsive envelope.
Gate outputs pre/post the HOLD STEP, EOC and total envelope period allow for example: the switching of rate or the delayed trigger of a second envelope during the envelope cycle.
Quality all analog circuitry
Gate and Trigger inputs can be used simultaneously
The Gate input can hold the envelope on the HOLD STEP
Gate outputs for Pre and Post Hold Step
Gate outputs for End Of Cycle and envelope period

"In excellent condition and fully functional. Most importantly it has had the essential regulator modification. The instrument has been well looked after, having been kept in a non-smoking and pet-free home studio.
The synth comes with the original user's guide and a suitable UK mains power adapter. If you intend to use it outside the UK you will require a 9VAC 1.3A adapter for your local mains voltage.
Ensoniq's swansong, the FIZMO is an incredibly rare and highly sought-after 48-voice synthesizer which uses 2nd-generation Transwave technology to create very organic sounds unlike any other synth available. The top panel is festooned with realtime controls for many of its features, including the unique and quirky 'F I Z M O' knobs which alter various parameters per patch. It is most revered for its ability to create immense textures and soundscapes, often from just a single note.
For deep diving using a computer, there is a reasonably priced Mac / Windows application available called Fauxmo which is a standalone editor / librarian GUI. It edits the instrument via MIDI in real time."
