The Cosmotronic Delta-V is a fully analog dual channel function generator with a dedicated VCA and cycle switch per channel.

It’s a versatile and powerful tool that packs a great amount of functionality in only 10HP.
Trigger envelopes, slew incoming gates and signals, or generate LFOs with control over both attack and decay.

Dedicated End Of Cycle outputs, a summed output, providing a mix of DC coupled outputs that handles both audio and cv. The dedicated VCA for each envelope provides plenty of room for experiment and more complex patches.

Without anything patched into the VCA’s input, the module produces variable cv, an envelope set by the Attack, Decay and Shape knobs. By patching an audio signal into the VCA input, the audio output signal will be shaped according to the settings of the envelope.
An LFO patched into the VCA input, will modulate the amplitude of the envelopes.
The slew input is used to slew (round off) incoming gates or voltages.

The overall shape of the envelopes is set with the Shape, the Attack and Decay knobs.
The knobs can be set to produce short, snappy or very long envelopes.
The Shape knob transforms the envelope from exponential to linear to logarithmic.

The minipots offer attenuverters to control the output of each function generator:

  • CCW – Inverted gain (negative)
  • Centre/12 o’clock – Fully attenuated
  • CW: Positive gain

The trigger input takes a trigger or gate to start an attack-decay envelope, the link switch on the front normalises trigger input 1 to trigger input 2.

There are many ways to utilise Delta-V.
