I already mentioned this as an idea to be developped as a single module or even better, as a device.
My solution here uses an 8-8 modular frame and also 8(!) multimode Filters for better flexibility...
MIDI CC 29-32 are assigned to decently affect the filter frequencies, 29 for hpf, 30 for high bpf, 31 for low bpf and 32 for lpf, each of them for both channels (l/r) equally, of course.
Opening the patch, you´ll also find l/r seperated VUmeters which can be set to show the specific frequency range by sliding the switches underneath them where 1 is for highs ... and 4 for bass.
inputs are 1/2 for l/r (what else did you expect?)
outputs are pairwise, 1/2 for high freqs l/r ... so os ´til 7/8 for basses... right.
Now you can process audiomaterial more specific than you ever did before, happy FXing!
PS.: I would have liked to use some non-resonant but variable Q filters, similar to parametric equalizers, but such do not exist yet for ModV2, afaik.
All D/P Scopers to battle station!!!
Make this one a small and most powerful device!!...pleeeeeze..?
that goes in a new way of sound design.
