Send a Variable Sysex Message over a Knob

Question

Hi,

I want to send a variable sysex message, but my problem is that the message has 2 variables on it:

Example:
F0 ............. 00 6E F7

The 2 variable numbers are 00 and 6E, and when the knob is moving, the first one is increasing ant the second one is decreasing.. like this:

Example:
​F0 ............. 00 6E F7
​F0 ............. 01 6F F7
​F0 ............. 02 6D F7
​F0 ............. 03 6C F7
​F0 ............. 04 6A F7
​F0 ............. 05 6B F7
​F0 ............. 06 68 F7
​F0 ............. 07 69 F7  .... etc .... Can I do this with a Knob?????
 

 

 

 

Answer 1

In order to give you support it would be easier to say what parameter on what gear you want to control preferably also the page of the manual that describes the sysex of the parameter. That way I and other people have a better idea of what might be going on.

At first glance the values you showed seem illogical, so I can't say much about it. Help me understand what your goal is.

Ok. From what I see in the manual there is only Midi CC. No sysex at all. Channel 1 Amp Gain is CC33. You can control CCs with a knob. To control Channel 1  Amp Gain you create the knob, choose Control Change as message type, select 33 and that should be everything to control the Channel 1 Amp Gain.

I am working right now with my Digitech GNX4, i Was able to control all of the effects with buttons ('cause they are mostly one sysex string) but when it comes to knobs the sysex message becomes variable on two positions.

This example im trying is to control the amp GAIN of the channel AMP 1, and the sysex message for the channel 2 and warp are similar.


Tnx for the response!

THANKS ... You were right, I was complicating myself with sysex. And yes Ch2 Gain is CC46, and Warp Amp CC83

Im doing the Layout for the whole GNX4, some of the parameters are not in the CC list, so I have to modified them via sysex. Once I Get more into trouble i'll be asking for more help.

Tnx!
