Can MT do this? - Bome Forums Archive 2005

Hi, I need to create some scripts to control Live and Ableton support recommended to check out MT as a possible solution. I read the relevant sections in the MT manual before installing it, but I'm still not sure if MT could do exactly what I need:

1.)
A set of translators which remap incoming MIDI Note numbers according to the following rules:

If the Incoming Note number is equal to a predefined value then a variable should be added to it (with an initial value of 1) and then the variable should increase by 1, until it reaches a preset maximum value, when it should get reset to 1 (just like an ordinary loop counter).

Here's an example:
Incoming Note # to watch for = 60
Number of steps in Loop = 8
Inital counter value = 1

Pressing Note # 60 on the MIDI keyboard for the first time should produce an Outgoing Note# 61, pressing it again will produce an Outgoing Note# 62 ... ... the 8th time it should be translated to Note# 68 and the next one should be 61 again etc.
------------------------------
2.)
Multiple instances of the same translator should run with different initial settings.
------------------------------
3.)
Translators should be recalled by Program Change messages

Can someone confirm if this is all possible in MT?

Hey Hungaristan,

This sure possible! And not too difficult either...

To add in a counter, you use simple rules that add to a 'Global Variable' until the limit is reached then reset it - Just ass you presumed. For the example I used the first Global Var, ga. This is initially set (as a decimal number in the rules, 96 is what 60 is in Hex). I am assuming your keyboard key that you want to use is 90 60 7F (80 60 00 OFF) and I have used the next key to reset the value back to your first state, 61.

Here is the Translators that make this up...

Code: Select all

Translator 0: Set Initial MIDI Note Value
Options: stop=false
Incoming: on activation of this preset
Rules: 
  ga=96
Outgoing: (none)

Translator 1: Step Up MIDI Note - Note ON
Options: stop=false
Incoming: MIDI 90 60 7F 
Rules: 
  ga=ga+1
  if ga>=105 then ga=97
Outgoing: MIDI 90 ga 7F 

Translator 2: Step Up MIDI Note - Note OFF
Options: stop=false
Incoming: MIDI 80 60 00 
Outgoing: MIDI 80 ga 00 

Translator 3: Reset MIDI Note Value Value
Options: stop=false
Incoming: MIDI 90 61 7F 
Rules: 
  ga=96
Outgoing: (none)

Have a try and let me know how it goes! I hope this helps...
