Hi. Is there any other way to control the speed of the jazz organ leslie speaker, apart from the 3 pedal unit? Yamaha P121 and P125.

Any external device that can send the same MIDI CC as the function associated with the appropriate pedal from the 3 pedal unit should create the same result.

I had my iPad connected to my P series and used a drawbar organ app plus others rather than the inbuilt ones

Galileo 2 and B3X are two apps whorth looking at

Its a pity Yamaha didn't think to add some button combination like Function/L that would trigger the rotor speed change. Perhaps we should lobby them for and firmware upgrade?

Hi - Thanks - I could do that but then I would rather just use my Arturia MIDI controller. I just hoped there would be another simple way as I don't play organ on the digital piano very often.

Yes - it seems like a strange oversight. Also - I don't see any other 3 pedal unit other than the one that attaches to the furniture stand which is not great for portability,

It depends on the midi configuration of the Yamaha. If the leslie slow/fast is mapped to a specific CC (say CC#1, which typically is assigned to the mod wheel), then you could take a single foot pedal, attach it to a device like this: link then program this linked device to send that CC# midi into the P125 each time the footswitch is depressed. This would then toggle the organ slow/fast speeds.

I'm not sure that this would work as we are talking about its built-in sounds.
I can't swear it will work without trying it, but in most cases, this isn't an issue. Imagine you had the 3-pedal unit (so you had the pedal that sent the rotary switch command), and you recorded your MIDI performance into a DAW (as people commonly do). When you played that MIDI performance back into the P-125, with most implementations, it will recreate the same performance. Meaning that the MIDI that was generated to register that rotary speed command would again be recognized when the keyboard received that same MIDI input back from the sequencer. So anything that can send that same MIDI command into your keyboard while playing should have the same effect. Since it is the

Which also gets to the info Delaware Dave just posted (and coincidentally, something I posted in an unrelated thread)... yes, that MIDI Solutions box he pointed you toward should allow you to configure a footswitch to send whatever CC the P125 needs, as should the Audiofront MIDI Expression iO or a Behringer FCB1010. Since it its the left ("soft") pedal of the triple pedal which changes rotary speed when the organ sound is selected, it is almost certainly going to be CC# 67 that you'll have to program your external device to send.
