Hi,
I am a beginner, but imo:
-I would change the 3 modules 2hp of clock modulation from a Pamela's New workout, more functions, similar money, similar size.
-You will need an audio output, a mixer or at least something that attenuates the outputs of your voices (vca's), this means at least 6 hps more.
-You are dedicating more than 50 percent of your case space to 3 modules.
-I would move to a larger case, or, I would sacrifice cellz and chipz modules.
-A couple of envelope generators would be nice too.
-Find in Youtube some demos of rides-in-the-strom DMO module, versatile, affordable and "in your music scope"
