I know it's probably something very simple but I have been trying to figure this out.

I'm using ableton live and would like to change its tempo using PD. Ableton can learn and accept MIDI note and CC messages from controllers to control various things like volume faders, knobs, buttons, etc. (Map mode)

I would like to use MIDI CC messages to increase or decrease (by one) so when I map the tempo to the "ctlout" it changes by one as well.

Mapping the tempo to faders or rotary knowbs works but the amount is not precise.

By the way i'm using touch OSC to interface with PD. So basically I have this right now:

[dumpOSC 8000]
|
|
[OSCroute /1]
|
|
[OSCroute /push1]
|
|

• |
  |
  [ctlout 1 1]

Thank you in advance.

I don't use TouchOSC or Live, but I think this patch should work. Keep in mind, though, that you're not going to get better accuracy than 128 values. MIDI cc's are 0-127, integers only. Unless Live allows you to set it up using the 14-bit paired cc's trick, but you would need two [ctlout] objects for that.

Also, this patch uses the mrpeach objects for OSC instead of the OSCx ones that those patch gens use. OSCx is deprecated and not as reliable as mrpeach.
