patch programmable multiple
The Patch Multiple is a passive re-sizable mult designed for performance use. Patches can easily undergo large changes by inserting and removing input signals from the mult.
The left column of jacks are all inputs, the right column of jacks are all outputs. When an input is inserted, the signal is multed to the output directly to the right and to all of the output jacks below. If another input is added, the mult from above is replaced by the additional input signal
These merchants probably sell this module. Huh?
