How to receive and display sysex sends from Moog Sub 37

Question

Hi,

I started to create a MD template for the Moog Sub 37. I don´t want to control the Moog with MD but instead I want to use MD to show me the parameter values or knob positions of the Moog, especially after loading a new preset. Unfortunately, the Moog does not display the parameter values of a preset, nor does it give any guidance how to adjust the knobs to the original preset values (as, for example, the Bass Station II or Moog Voyager do).

Now, when I manually rotate the knobs of the Moog, the corresponding knobs of the MD template go in sync and also show the correct positions and values. But when I execute a sysex send of all preset knob values on the Moog, there is nothing in the MD log, and no knob adjustment. My iRig Midi 2 interface for iPad shows the incoming signals, but that´s all.

I guess it´s because of me doing something wrong. Any advice would be helpful. Thx a lot!

Hi there, Dan here, I'll be off grid until September 7, if no one helps you before then, I will. Thanks!

The knobs in your MD layout react on midi commands. A sysex send is not a collection of midi commands. It is a collection of bytes that describes your preset. Your knobs won't recognize the bytes because they are not midi commands.

Thanks for the reply! I know that sysex sends have a different (hexadecimal) format than midi (CC sends for example). But my understanding was that MD can also handle sysex commands. So my plan was to program the knob mapping in the MD layout to the corresponding sysex commands. I thought I could receive a single patch sysex dump and divide the sysex send into many single knob parameter value commands. Like, for example, with the iPG-800 editor for Roland Alpha Juno. I thought I would also need the Moog sysex data structure for this.

So my question still is: Can MD receive a sysex dump and translate it into several knob parameter values? Or is that generally impossible?

Hi dbeats: the short answer is "no." There's no way for MD to parse sysex if it's not one sysex message per control. A MIDI-dump mapping feature is a cool idea, and would definitely be useful. We'll consider it for future versions, but it's probably not forthcoming: the complexity of the feature, wide range of inputs, and difficulty in providing a simple UI make it a hard sell for us.

I hope that helps.

Thanks!

Dan, I think it is possible and really desired function ... here I posted a start point (understanding each device would have it’s own parse file the same as it has layout file http://mididesigner.com/qa/5103/how-does-your-midi-targets-bulk-dump-work

Answer 1

As far as I know MD can't translate sysex dumps unless the sysex dump is a collection of sysex commands instead of a collection of bytes.

I hope Dan can shed some more light on it when he returns.

Thanks EZB, I'll comment on the question above.
