how to inc\dec tempo by 1

Post by rickbol »

Is it possible to remotely access the the increment\decrement tempo "buttons" on the SLGui via either midi or osc?

Currently I'm working with Non-Sequencer, Mididings and SL for live performance. SL is the timebase master, and Non-sequencer follows it for tempo and time signature. I have the need to vary tempo somewhat over the performance. The tempo "buttons" in SLGui work perfectly, but I need to perform the same function with my foot controller. Since I have mididings, I can map to midi to osc if that's required or preferable.

I'm hoping to access increment\decrement-by-one directly to avoid the latency\complexity of:

Code: Select all

"/get" the current tempo value
add or subtract one 
"/set" the tempo
(I'm currently having difficulty with mididing's osc functionality).

It's likely that a may not, in the end, actually have SLGui running, so the best solution for me would not require it.

No, there is no tempo increment or decrement command in the OSC interface. I'm afraid you'll have to do the /get /set thing, or perhaps just cache the current value to avoid the get (may not be feasible in mididings) ? I doubt the latency will be much of an issue, either way.
