mapping tempo controls via midi

[indigo_osc]

Hi Guys,

I've got an akai mpk mini and I am trying to map two of the pan pots to the coarse and fine parts of the tempo control in live. It works fine, apart from the fact that the fine control jumps around. For example, if I try to dial in .95 bpm it jumps to .81. I then dial up to, say, .30 and it jumps to .19 ...

In other words: It is impossible for me to hit something bang on. There is some kind of glitch and i can not figure it out!

MIDI CC has only 128 values of resolution, it won't match with BPM (which goes from 20.00, 20.01, 20.02, etc. to 999.00).

You can try to restrict the range to a multiple or divisor of 128.

Or just ignore if you want to work on your OCD

I dont get it: the fine control only goes from .00 to .99? Thats 100 steps. That should be no problem with relation to midi's 128 steps??

Nice one with the OCD. Always needs work.

Ah, I got lazy and didn't try it myself (my MIDI controllers are not always connected), and assumed it would work like any knob.

But I just tried and saw what you mean, the x.00 doesn't scale 1 by 1.

Seems it is locked to 0.02 increment per step, and always will add 2.56 BPM when a MIDI CC is at the 127 max.

I think you can report this to support as a bug.
