and the link to the actual public rack - not just a jpg!!!
the rack looks like a completely un-thought out random collection of cheap modules with little to no research having been done before hand
and the patch doesn't make a lot of sense...
the output of your quantizer wants to be patched into the pitch input of your vco (or vcos via a buffered mult) and the output of the sequencer wants to be patched to the input of the quantizer!!!
the sequencer needs to be clocked - where is the clock coming from??
you need to open the vca with an envelope - where is this coming from?? where is the gate needed to open an envelope coming from?? or are you just interested in drones? in which case a mixer would be better than a single vca!
no modulation???
no mixing - you have 2 sound sources, but no mixing - no sub mixing to sum the waveforms from the individual vcos, nor to sum the 2 vcos - so both vcos can be filtered
invest in a quad cascading vca - use it for modulation as well as audio!!!
the patchbay is superfluous - ie completely and utterly useless - apart from using more patch cables than needed in a rack this size - maybe in one 5 times the size or when patching between a couple of larger cases it would become useful - but for now what's the point????????
please take a look at my signature... read it, think about it, ask questions based upon it... at the moment you appear to be floundering - like a flounder on a slab waiting to be filleted - not in the sea where it can swim!!!
"some of the best base-level info to remember can be found in Jim's sigfile" @Lugia
Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
