Everything you could ever want to do to modulate a CV signal, packed into a single 1U device!

The design goal for Dual CV Source is to give you everything you could possibly want to do with a CV signal – that isn’t an LFO or Envelope (well handled by Reason’s built-in Pulsar device) – and pack it all into an easy-to-use 1U device.
