Hi,

don't know what you want to do. Please explain it step by step...

do you want to define two keys (on computer keyboard? or on MIDI keyboard?) that, when pressed, increase (or decrease, respectively) controller value, i.e. a fader or slider in a program?

Thanks,
Florian

hi,

yes, florian, that's exactly what i wanted. i should know better than to ask for help without properly describing my problem. won't happen again.

anyway, i think i have it down:
--------------- Preset fx select incr

the thing i've spend most time on was making it go from 0 to 127 and reverse.

the values are a bit strange, but they match the sixteen steps on an apc40 encoder (including zero), so i have a visual indicator from the knobs' led circle.

the last three translators are for resetting to zero if the decrease button is held for more than 350ms.

it's a lot of translators, is there a quicker way to do this? what if i wanted 128 steps?

Hi,

yes, that's a good way to do it.

In order to optimize it, you can formulate the outgoing controller value as a mathematical expression:

Your translators #1 to #16 can be combined into one single translator. Use a rule to compute an outgoing value in the variable pp:

Code: Select all

Translator: Send increased controller
Incoming: MIDI 90 3D 7F
Options: swallow
Rules:
  pp=ga*8
  if pp>=128 then pp=127
Outgoing: MIDI B0 17 pp
The factor 8 determines the step size. E.g. if you use 6 instead of 8, it will increase slower.

As I understand it, you want the values to wrap around, i.e. if the maximum is reached, start over from the beginning. Then you can write translator #0 as such:

Code: Select all

Translator 0 :+
Options: swallow
Incoming: MIDI 90 3D 7F
Rules:
ga=ga+1
if ga>15 then ga=0
Outgoing: (none)
Of course you can also optimize the translators for decreasing the value. And I'd put the increase/decrease translators at the bottom so that they are executed AFTER sending the controller value.
Final preset:

Code: Select all

Translator 0: Send increased controller
Incoming: MIDI 90 3D 7F
Options: swallow, NOT stop
Rules:
  pp=ga*8
  if pp>=128 then pp=127
Outgoing: MIDI B0 17 pp

Translator 1: Send decreased controller
Incoming: MIDI 90 3C 7F
Options: swallow, NOT stop
Rules:
  pp=ga*8
  if pp>=128 then pp=127
Outgoing: MIDI B0 17 pp

Translator 2 :+
Options: swallow
Incoming: MIDI 90 3D 7F
Rules:
ga=ga+1
if ga>15 then ga=0
Outgoing: (none) 

Translator 3 :-
Options: swallow
Incoming: MIDI 90 3C 7F
Rules:
ga=ga-1
if ga<0 then ga=15
Outgoing: (none)
Of course, leave the three timer translators as they are.

You could even combine Translators 0 and 1 into one, as they are identical except the incoming trigger. You could use "MIDI 90 qq 7F" as incoming, and check in the rules that qq is 3C or 3D. But probably that wouldn't optimize performance.

Hope that helps!
Florian
