Ive played around with this with an experimental group.
The thing we found was
- No matter how close micd there was a ton of bleed from other drums and instruments even resonance of the drum heads not being played by guitars, basses.
- So what worked best was
a. A mixer with solo buttons for each drum
b. A multi filter pedal, the band pass being especially important, Placed before the other effects.
That allowed focus on an individual drum’s individual intended frequency range for effects. A Kaoss pad would have been great for this iirc this was before that existed. 1997? Our drummer had half a dozen pedal, guessing Kaoss pad would cover them all after the mixer and filter.
You could also do the above with a mixer and iPad. Audiobus, a filter, some of the Audio Damage mods and such. Is it a computer? Okay maybe but less going on, less to break.
