Expander for Looping ADSR/VCA
The standard Oakley single width ADSR/VCA module can be upgraded to full voltage control with an addition of an extra module called the "ADSR Upgrade Module". This module takes up 1U or 1MU of panel space, and is fitted next to the standard ADSR/VCA to be controlled. The upgrade can be added on at any time and installation is very simple. Two small four way interconnects behind the front panels allow the two boards to 'talk' to each other.
Each of the four CV inputs is controlled by a dedicated pot. This pot acts as a reversible attenuator, so that the gain of the input is anything from -1 to +1. This means that any inputted CVs can subtract or add to the times, or level, set by the ADSR pots. With any input knob set to its middle position, then that CV channel is effectively turned off.
These merchants probably sell this module. Huh?
