I’m not sure exactly what you are asking but if you want to use a few bytes of incoming SysEX as global variables to adjust the output (IE CC number and value) or visa versa, then yes. Steve Caldwell Bome Customer Care * * * _Also available for paid consulting services: bome@sniz.biz_ ---

ok… here they are i got 2 rotated knob with midi number0-1 (var pp) -if i push a switch make it as ga=0 thenpp=pp - push switch again then ga=1 thenpp=pp+10 (different midi number in same knob) problem is if i want to add another global var (push another switch). how to get another different midi number on that knob. im running out knobs, buy got a lot of switches. thanks in advance ---

I’m not sure if this is what you are asking. This example has 2 knobs and 8 buttons. The first knob input is CC21 and output is CC 0-3 depending on which switch you push. We use the value of the buttons (note 0-3) to determine the CC The second knob input is CC21 and output is CC10-13. We use the value of buttons (note 4-7) to select the output. The global variable ga controls the CC number of the first knob and gb controls the CC number of the second knob.

Yes there are but you might need to set up your Alias "My Controller’ to point to the device that you are using. You can do this in the MIDI menu of MT Pro ---

Click on the second preset called “Knob Assignment”. You will find 4 more translators there. ---

but i assumed this knob are controlling with gkobal variabel grom each switch right? my needed is to control knob with 2 global variable from 2 switch. so every time switch pressed the knob will produce different midi CC even tho its same knob that rotated ---

The way I set it up is to use different switch to set different CC for each knob but you can use a single switch to cycle through values if you want Rules would look like ga=ga+1 if ga==5 then ga=0 This would cycle from 0-4 as you push the same button.

hmmm… im not succeed yet steve…but i got it always in my head… …i think it judt miss communivstion between us…let say there are 3 switches(switchA, switch 1n switch2) n 2 knobs and they were only send sysex . what i need is: 1)unpress switch A (ga==0) & press switch 1(pp=00)… it will choose amp preset 1 , then knob 1 should translate from sysex to CC to control vol of amp preset 1, meanwhile knob 2 should translate from sysex to CC to control pan of amp preset 1 2)unpress switch A (ga==0) & press switch 2(pp=01)… it will choose amp preset 2, then knob 1 should translate from sysex to CC to control vol of amp preset 2, knob2 is for panning it 3)press switchA (ga==01)&press switch 1(pp==00).it will choose stompbox 1 in preset 1,then knob1 should control vol & pan of stompbox in preset 1. 4)press switchA (ga==01)&press switch 2(pp==01).it will choose stompbox2 in preset 1,then knob should control vol & pan of stompbox2 in preset 1. and so on. can i do that? how? i spent half an hour just to type this… lol ---

PS: switch A is to determine wether is on preset mode or stompbox mode Switch 1-2 is choosing which preset n which stompbox knobs will follow it. ---

OK, maybe I get it now. Is this what you are looking for? Switch A Pressed = Stompbox Switch A Released = Amp Switch 1 Pressed - Preset 1 of Stompbox or Amp depending on Switch A Switch 2 Pressed - Preset 2 of Stompbox or Amp depending on Switch A Only Switch 1 or Switch 2 can be used at a given time Pressing one deselects the other This requirement is really beyond the scope of free support so if you want me to build it, please contact me via email. In general, however you need to have 4 presets: - Amp Preset 1 - Amp Preset 2 - Stomp Preset 1 - Stomp Preset 2 Your buttons need to disable and enable 1 of the 4 presets created in MT Pro Stomp Preset 1 should be enabled by default (set at project start) All other presets should be disabled by default (again set at project start) In your design you want only 1 preset at a time so set up your presets to automatically disable other presets when set. Then it is a matter of looking at the state of Of the 3 buttons to determine which preset is selected A and 1 Selected - Enable Stomp Preset 1 A and 2 Selected - Enable Stomp Preset 2 A released and 1 selected - Enable Amp Preset 1 A release and 2 selected - Enable Amp Preset 1 Then put your encoder SysEX assignments as translators within each preset. You can use the value of ga for Switch A (0 when release and 1 when pressed) You can have switch 1 set gb to value of 0 when pressed You can have switch 2 set gb to value of 1 when pressed So your rules would look at value of ga and gb to determine the preset you need. ga=0 gb=0 - Stomp 1 ga=0 gb=1 - Stomp 2 ga=1 gb=0 - Amp 1 ga=1 gb=1 - Amp 2 Again, if you want me to write this for you, reach out to me via email and I can provide an estimate. Hopefully though you have the logic now to be able to handle yourself but I’m happy to help with paid services.
