Tempest

Tempest was my idea of a dream synth, it was to have the following features:

The Oscillators not only have 100 digital waves, plus saw, sine, noise and PWM but also the ability to 'de-res' at two different levels. You also have the ability to hard sync oscillators for those classic screaming lead sounds.

The mixer section is similar to the prophet-VS, a two dimensional mixer. you can turn on and off the oscillators at the mixer so if you don't want the sound to be full you can thin it out by dropping oscillators.

The VCF is based on the classic moog ladder, but as with defender you have the ability to pole sweep the filter from the classic 4 pole sound through to fizzy, rich, 1 pole sound. In the middle you get a bandpass mode, this is all controlable via LFO and/or ADSRs.

The modulation routing was extensive, for example you can route the LFOs to oscillator pitch, pulse width, filter resonance, filter cutoff, Filter drive, filter slope, VCA, mix-x and mix-y. The LFO's can also be put into 'one shot' mode, so they only trigger when you press a new key. So they could be used, for example, for sweeping oscillator picth whilst synced. And the LFO's can be set to follow the note you're playing, creating some truly rich sounding polyphonic sounds.

The third ADSR has the same routings as the LFOs, plus the ability to control the depth of LFO1.

Finally there was to be an analogue chorus unit aswell, based on the classic designs using BBD's from the early 80's, to give it that rich full sound so loved on many classic synths.
