Great idea… but… I’m a bit confused “arm both this sample and the…etc.”
Is that as in:-
1. Load two sample files into one sampler? Don’t think that’s possible.
2. Feed an audio signal into the sampler to be processed (by the fx sample file)? Don’t think that’s possible but would it be great if samplers could do that.
3. Load each sample file (Piano and Mercury FX) into their own separate sampler iteration, and play them both at once (same midi channel)? Is that it? That’s the only way I can think of this working.
