Subject: SDS7 Voice Card databus question

From: hr.public@...
Date: 2016-04-16

Looking atThierry’s amazing reverse engineering of the SDS7 voice board I’m wondering onething.

 

Accordingto my understanding all CV’s to alter the dynamics of the sound seems to be extractedfrom the trigger input on each individual voice card. No need for the CPU to actuallyknow dynamics.

 

Are there S&Hcircuits hidden on the Hybrid module in conjunction with the VCA’s? Enabling theCPU to burst stored kit data continues to the bus.

Or does theCPU actually wait for a trigger input before bursting corresponding data totrigger source?

 

If possibleI love to see Thierry’s schematic for his single voice test board? I guess thatpaper will fill the void.


Thanks!
Hans
