Well, I tried a pitch-shifter modules but it sounded terrible at anything about a few semitones. Also fairly CPU-hungry.

So I looked up the circuitry for a standard D-type flip-flop pulse divider and tried to build it in SE.

Not only did it fail horribly because you can't use real feedback in SE (which the circuit requires), but anything in the audible frequency range was horribly aliased and used 50% of the CPU. FOR ONE DIVIDER.

Can't use standard doubling circuits either because they require feedback as well.

Back to square-one, I guess.
The only thing we shouldn't know is what we can't do.

It is possible to make a flipflop with little CPU, or you use the binary counter. But anyway as you saw already you'll get heavy aliasing.
The only ways I found:
- code a special module in C (don't know enough for that)
- use a seperate container with 60 tuned OSCs for the 60 notes and route the signal with a midinote2switch construction.

a flip-flop would alias like hell..
60 oscs will eat the CPU for breakfast
It doesn't matter how it sounds..

And today in 2018, is there a solution ?

Preferably for a development in the current 64-bit Synthedit 1.3.
