Hi Jim, thanks for the note.
In my big studio rig, I do have a bunch of relevant scale/offset/mix utilities: Maths, Sum*Diff, SISM, Levit8, Doepfer A 1-38m Matrix Mixer, and 12 lanes of VCA (3 quads). I also have plenty of CV sources from standard envelopes, LFOs and sequencers through chaos and random. Your tagline of "sound sources < sound modifiers < modulation sources < utilities" I've tried to keep in mind for my modules --> but I probably haven't kept it in mind for all my actual patches!
So I'm probably vastly under-utilizing my existing scale/offset/mix utilities --> my current guess I should press my upcoming patching to have i) a lot more modulation targets and ii) nearly all mod signals "dialed in" or restrained via attenuate / offset / mix.
I think one challenge I've had on this point so far is not having a great sense "what good looks / sounds like" in terms of #s, balance and specific patching techniques for modulators + utilities in Eurorack patches.
Thanks for the ideas folks!
Nicholas
