Ok, this is going to sound a bit crazy.
I want to use Petrof mistral dreamy as my base, then morph that into cimbalon starting the morph about A2 to pure cimbalon by A4. Then from c6 to the end, some form of percussion bells, but I want to map C4 of tubular bells to C6 on my keyboard.
Is this possible?
All of this is for ONE echo of hte main motif?
You might have better success doing that in a DAW with multiple instances of PTQ. I know you could route that many different instruments and layers in OTQ, but I don't think PTQ will give you that level of flexibility/precision in the standalone. That said, if you could run multiple instances of the standalone and have them listening to the same port (which usually doesn't work as one instance tends to "own" a given port if multiple are open), you could pull it off without a DAW, but I think you'll have the best success running two or three instances in a DAW and mapping them manually.
