Yeah thats what i had in mind (eg to ask StudioSpares to do this is a standard piece, so its cheaper than custom
(which it seems they WILL make if you ask nicely
)
Another config that might be useful is 3.5 Jack -->> TRS 1/4" Jack -->> TR(mono) 1/4" jack
meaning each drum source could be patched into an FX send return loop, for those who are wired that way, with individual 1/4 jack outputs to mix from
SO digging my pads right now...
