You could just buy a cheap hardware synth. That's how we did it in the
old days.
Or tune the open strings of a guitar with a tuner, loop it and play
along with the fretless.
And suddenly it's not a case of a lot of practice, but a little experience.
89/47 is 1105.373 cents. Not too far from a 1100 cent 12tet M7th.
I used to do MIDI composition that had loads of ratios and rhythms,
I stopped that when I started getting performances. I started getting
minimal
when the performances sucked and I started performing with a guitar
controller
and microtonal synth letting go of the rhythmic possibilities.
Tuning with ratios makes a better connection with the listener.
