Two equal sliders sending different values

[Saturnix]

Hello,

 

I’m trying to create my own controller for the TX-802 and this program is really amazing!

However, I’m having some difficulties: I’ve made two sliders, inputted the same SysEx formula but, as I use them, I see from the console they’re sending out different midi data.

 

Here you may find a difference check between the XML of the two sliders:

As you can see, there are only marginal differences (related only to the interface position and index).

and here are the different messages they output in my midisport (where XXX is replaced with the slider value):

[MIDI OUT][14:45:23:000780]: [MIDISPORT 4×4 Anniv Port A][176 001 XXX]
[MIDI OUT][14:45:25:000401]: [MIDISPORT 4×4 Anniv Port A][240 067 016 000 105 XXX 247]

 

Second perplexity, not so relevant… I still don’t understand how CTRL is able to understand to translate my SysEx formula into that message. The formula is: “F0 43 10 00 69 XX F7”: how does he understand to replace XX with the slider value? That’s correct, but who told him to do so and where?

 

Many thanks for your time 🙂

 

EDIT:

I’ve fixed the first problem. Basically, it is all about switching MIDI message type from 0-CC to 5-SysEx for both the sliders. They were already the same but, for some reason, CTRL was still sending out SysEx even if instructed to send CC for one of the sliders.

If you set it to CC it will send CC messages with the value parameter replaced by the current modulator value (whatever your slider value is set to).

if you set it to SysEx the formula is used, open the SysEx editor to see other formula tokens that can be used, XX is just one of many.

XX means, put the value of that’s currently set for the slider, as a 7 bit INTEGER in that place in the message, so for F0 01 02 03 XX F7, put it as the 5th byte in the message, and send it out.

For CCs delete the formula it’s not needed, CCs are those well-described messages, the always consist of 3 bytes. When in doubt consult the MIDI specification http://home.roadrunner.com/~jgglatt/tech/midispec.htm

Many thanks for your precious help! I understand now, but where can I find the SysEx editor with the other SysEx tokens?

On the left of the SysEx formula there is a button: Edit, it opens the editor, right click on any byte to see what tokens can be inserted.
