Help: Send SysEx to Virus C using Lemur for iPad

Post by bammer » 27 Dec 2011 21:17

How can I use a knob in Lemur for iPad to adjust portamento speed via a sysex message?
The sysex message I would like Lemur for iPad to send to my Virus C is to change Portamento speed and is listed as follows:
0xF0, 0x00, 0x20, 0x33, 0x01, 0x10, 0x70, 0x40, 0x05, (portamento speed variable (hex) 00-7F would go here), 0xF7

I'm a little frustrated the manual has virtually no coverage of sysex. Any help wold be greatly appreciated.
I downloaded MIDI-FXv1.5.jzml thinking I could disassemble what the creator did to get sysex to work but I had no such luck.

(I've been using MIDI Touch but it's just too buggy so I'm trying Lemur instead.)

Never mind. I figured it out. This instance uses Filter 1 Cutoff.

1 - create a fader named "Fader2"
2 - make the message system exclusive
3 - click the Custom Midi button
4 - set trigger to Fader2.x
5 - set data to {0x00, 0x20, 0x33, 0x01, 0x10, 0x70, 0x40, 0x28, 127*Fader2.x}

note: Don't include F0 and F7, respectively. The custom midi message splices that in for you,
I found the info I needed at the old Jazz Mutant forum.

Hi
Be aware however that custom midi are not bi-directional so you will not implicitly receive return info from the synth . . .

true, but i wonder why it´s not possible to send sysex direct from the fader, you can select system exclusive but it just doesn´t take the sysex string. the moment you click on an other item, the data goes to 0,0,0,0.

Hello, I'm trying to do this with the Lemur Editor on Mac but I can't get it to work, the trigger field is greyed out and it show x[0] (not Fader.x) and when I put Fader.x in the data field, it's red as if the syntax was incorrect. What am I doing wrong ?

Ah found it by myself, there is a custom midi message button at the bottom right of the screen.
That's really nice ! Can now send 14 bit messages via sysex to my custom midi to dmx controller !
