Hi - I can't seem to find the MIDI command that will trigger or toggle ROTARY SPEED (fast/slow) on Yamaha Genos. They have a huge list of functions one can control on the MIDI, "External Controllers" page, everything under the sun is on the list, except Rotary Speed (Fast/Slow)!

I can't find reference to a CC# that will do this, nor a NNPR or SysEx or anything.

I'd like to have a MIDI programmable button on an external device, send the appropriate MIDI command to tell Genos "Toggle the Rotary Speed Now".

Can this be done?
Thanks!
Jim

Jim ask here maybe you will get the answer..

Hi - thanks - yes, I did post this question there as well . . .

Jim there is no predetermined cc code for fast/ slow.
Most manufacturers use cc#1 mod wheel/lever. You can do a midi learn and assign where you want.(DAW).

It would be nice if even a SysEx code could be found that literally did the same thing as pressing the RotarySP button ... toggled Rotary speed (then you wouldn't need one button for Fast and another for Slow on the external device, or need to use a slider or wheel) . . .

Just hoping that Yamaha can tell which command tells the Genos to do the same thing as pressing Rotary SP . . .

Thanks,
Jim

Jim,
It says in the parameter chart of the Genos Data List that rotary speed can not be MIDI controlled. However, it lists so many different rotary control features that can be MIDI controlled.

Chris

The LFO speed and depth parameters are adjustable using XG
parameter change sysex messages. Page 64 of the data list.

Not particularly convenient.

Is there / has there ever been a hardware controller available that handles XG parameter changes by mapping to a slider or knob?

Hi - thanks for the various info that people have posted. What is interesting is that Rotary Speed (Fast/Slow toggle) can be assigned to an assignable button, and can be assigned to a footswitch plugged into the Genos. And that the Extrnal Controllers list of items that can be controlled is huge, but omits Rotary Speed (Fast/Slow toggle). It certainly sounds like it would be technically possible for Yamaha to have allowed this control to be triggered just like the other ~100 items on the list for External MIDI Controller; I think it was just an oversight; somehow the engineer didn't happen to include this one item on the list.

I'm going to try a MIDI Monitor on the Genos to see what is sent (if anything ) when I press the Rotary SP button . . .

Jim

I got my answer: When I press RotarySP, the following is sent:

on/Fast:
10:13:48.156 From MIDI SysEx Yamaha 9 bytes F0 43 10 4C 03 01 02 01 F7

off/Slow:
10:13:48.897 From MIDI SysEx Yamaha 9 bytes F0 43 10 4C 03 01 02 00 F7

Now if I can get my controller to send this MIDI string . . . ?

Just curious but does the Rotary Speed ramp up and down when you cycle the Rotary SP switch or does it immediately go fast then slow? On my Tyros models, the default on the mod wheel goes fast immediately then stop on the opposite throw of the wheel.
