i haven't been following this thread too closely but regarding these
last few emails
all you need is [expr].
[expr pow(2, $f1/12)]
-> for ratiometrically determining frequency difference between each
interval in equal temperament
--> typical input in range -12 to 12 (deviation in half steps)
[expr (440.0*exp(log(2.0)*(($f1)-69.0)/12.0))]
-> convert midi note numbers to Hz
--> typical input in range 0 to 127 (midi note number, lol)
./d5
