The Midi-CV Mod VCA is a performance orientated VCA ,
there are two ways of controlling this VCA. The Midi control
input is routed to the Midi controlled Mod wheel output
(this may be isolated). Although primarily designed to allow
modulation control from midi this versatile VCA can also be
controlled by an analogue CV patched to the CV socket.
This socket is the control input to open the VCA when used in the CV analogue mode. It can be used even if the
internal Midi route is active.
This socket is the signal input to the Mod VCA. Audio and control voltages can be accepted by this input.
Example 1.
A waveform from the VCLFO coming into the signal input can have its level controlled by an analogue voltage by
the CV this variable level control waveform available at the out socket could then be used to modulate a VCO or VCF.
Example 2.
An audio waveform could be sent to the signal input of the VCA as the CV is increased, the output waveform
level would increase patched to the ext sig in the VCF, a performance control could increase the level of the external
signal into SPAWN.
Two outputs are available from the Mod VCA simultaneous control of VCO pitch and VCF frequency is available.
*Note only Midi is pre-routed, all signal in’s, CV in’s and outputs must be made using the patch sockets.
