yep. i'm here but sorry, nope.

there aren't plans to have separate outputs for each element, here
called like so as each map to a sample triggered per midi note key and only.

why not use several drumkv1 instances? each one loaded with its own set
of sample elements (if more than just a single one (you might keep an
exclusive mute group under the same instance eg. open and close hi-hat)?

i know it might seem a ridiculous solution, but hey you're not wasting
nothing much in resource terms, because each instance only loads the
sample(s) it is supposed to run anyhow ;)

hth.
cheers
