Teletype doesn’t do decimal numbers (in my understanding). BPM just did this:
60,000 / [BPM]
Depending on the value, you could get a decimal value. TT will ignore the decimal. Example:
87 BPM = 689.65517....
TT will just set at 689 ms. (I could be wrong and maybe it rounds instead of just dropping the remainder for BPM, although I’m certain the standard division just drops the remainder – not at the synth rn)
TT is a great leading clock, but I’d advise using a dedicated clock module (or setting temp at TT first and syncing your other gear to it manually), due to the ms limitation. It’s not really a resolution issue (ms increments are actually “higher resolution” than BPM), but more of a ‘unit conversion’ issue.
