So I bought four of them in a single module from Mutable Instruments.
Not much to add here other than this excerpt from the MI website :
"Veils provides four VCAs with an adjustable response curve.
Veils’ outputs are daisy-chained, allowing adjacent groups of 2, 3, or all 4 channels to be mixed together."
As its becoming crowded inside the synth case, Bob went down and gave me a hand to plug the module on the bus board.
More to come....
