I don't know if it's the right place, but I'm trying, unsuccessfully, make a fancy octaver.
What do I need? Both, An octave octave down, but with a catch: From E1(or below) to b1 the octave only plain instrument, and from C1 and above the octave start to blend in till fully engaged about F2
I don't know if its possible, but if someone have an idea, i will appreciate
Thanks
PS: a fancier one will be both, octave up and octave down, but octave up only engaged from below E1 to A#1 and start to blend out and fully disengaged about F2
