Hello, my first Bome script.. ie. how to Bome properly? - Bome Forums Archive 2005

Hi,

First of all, let me say I'm really excited about joining the Bome club!

Been reading this board a bit, but getting around to catching up soon.

Just wanted to ask some opinion about my first bome script. First it's probably good to explain my intentions with the script.

I have a MPD218 pad controller that is triggering notes of a drum machine. I want to reserve the first four pads to special functions, while the 12 pads underneath are sending midi notes to trigger the drum sounds / synth notes.

So I have mapped the first 4 pads to transmit midi notes 124, 125, 126, 127 on channel 16
The remaining pads are triggering notes chromatically from notes 000-011 on channel 01

Now the script itself has two translators. First one handles program change increment, and the second one handles program change decrement. Here is the code:

Code: Select all

Project: MPD218-AR-CTRL002
_____________________________________________________________
[x] Preset 0: MPD218-AR-CTRL001

[x] Translator 0.0: MPD218-PRGC-INC
Incoming: Takes Note #127 from ch16 of MPD218 and converts to pgm chng (+) - if pgm chng = 127, action is ignored, on port MPD218 Port A
Rules:
  if gp==127 then exit rules, skip Outgoing Action
  gp=gp+1
Outgoing: Program Change on channel 1 with program:gp, to port Bome MIDI Translator 1 Virtual Out

[x] Translator 0.1: MPD218-PRGC-DEC
Incoming: Takes Note #126 from ch16 of MPD218 and converts to pgm chng (-) - if pgm chng = 0, action is ignored, on port MPD218 Port A
Rules:
  if gp==0 then exit rules, skip Outgoing Action
  gp=gp-1
Outgoing: Program Change on channel 1 with program:gp, to port Bome MIDI Translator 1 Virtual Out

Does it look like I am doing everything correctly? I am asking because it's my first script and I am not 100% sure the script works flawlessly.. Like, is it safe to use a global variable for translating data like this? Should I copy the value of gp to a local, say, "pp" before going out from a translation? Also, what about note offs (velo 0), will they cause the translations to run twice or unpredicatbly?

Cheers

anyone? I'd appreciate any feedback

Oh fudge, seems like I am doing this totally wrong! Just checked the midi logs, redundant ugly data spilling from every orifice! I need to add some cleanup it seems..

Yes, after adding cleanup translations I get clean translated MIDI!

Still I don't know how to drop the redundant prog changes of 0 and 127 from the prog change boundaries while still "swallowing midi", but this is good enough for now.

Hi tsutek

Sorry for the delay, I'm back in the land of the living again. I can now answer questions. Your code looks fine.

Are you getting the top and bottom (127 and 0 respectively) program change messages sending when you don't want them to?

Hi,

thanks for getting back to this!

Yes I am getting redundant pgm chng 0 & 127 values, any ideas how to prevent those from getting sent by the script?

Alright, can we make some small changes to the rules, using labels, to try and isolate the problem?

In your rules section for note 127, change it to:

Code: Select all

if gp>=127 then Goto "Skip"
gp=gp+1
Exit rules, execute outgoing action
Label "Skip"
Exit rules, skip outgoing action

And for note 126

Code: Select all

if gp<=0 then Goto "Skip"
gp=gp-1
Exit rules, execute outgoing action
Label "Skip"
Exit rules, skip outgoing action

Let me know if that works
