Need a Little help with roland panel uicombo

[J_Klitzke]

Hi
I have a roland mixer vm-3100 . Im tryig to get a uicombo button to send a systx patch change
there are 100 patch’s in my list. If you look at the pic (vm-3100 param) look at the top
section
cc oo | 20 -7f effects patch name 1

cc 09 | 20 -7f effects patch name 10

This is the sysx im using, but it doesn’t work? ( f0 41 10 00 15 12 00 34 00 xx z5 f7 )
Thanks jk

Because this sysex doesn’t change a patch. 34 00 XX to 34 09 XX just gives you one patch name of 10 digits/ letters when you receive a dump. With xx being the character/digit. It wouldn’t work anyway because XX doesn’t represent a character, only 20 to 7f does.

To send a patch change you probably need a different offset address and a different start address corresponding with the number of the patch you want to change to. Hard to tell which because I can’t see it in the pictures. Need the whole sysex implementation for that.
