PSR S670 and Garageband 10.2.0

[gayajay]

Hardware setup. iMac running garageband 10.0.2. and Yamaha PSR S670. The PSR is connected to computer via USB port and also have audio outputs running through a XENYX Q802USB.
I'm not recording midi from the PSR. I simply use it as a controller for garageband instruments. But I do have it connected as an external instrument.
The problem that I'm having is that the track settings keep changing. Which ever track the PSR is assigned too, I'll select a different variation of a particular style and it will make changes to that track. For instance, it will cause the volume and panning to go up and down and left and right. It's really annoying.
Can anyone tell me how remedy this?

Thanks. Kind regards:
AJ

How do you have the MIDI transmit set up on the PSR-S670? I believe you can set it to transmit the keyboard parts but not the style parts.

Are you using the channels of the style parts to control instruments in GarageBand?

Actually, now that I think about it, your problem may be even simpler to solve:

When you add a new MIDI or virtual instrument track in a DAW, there is an extremely annoying tendency on the part of DAWs to set the MIDI input on the track to "All MIDI input ports" and "All MIDI input channels." This would mean that any changes in the channel volume and channel pan settings associated with the style channels are getting lumped in with the channel messages associated with the keyboard parts, causing unwanted changes to the virtual instrument that you've assigned to that particular track in the DAW.

You should go into the MIDI settings of the tracks in the DAW and change them so each track "listens" to messages coming only from your PSR-S670 and only on a specific channel.

I just spent a little time playing around with GarageBand on my iPad, and I didn't even see any options for changing the track settings, in which case you'd need to go into the MIDI settings on the PSR-S670 and change them so the keyboard transmits just the part you want to use for playing virtual instruments-- which would most likely be the Right1 part.

However, I didn't have any of my keyboards connected to my iPad at the time, so that might be why I didn't get any options for selecting a MIDI input device.

Also, are you using GarageBand on an iPad or on a Mac? There are probably some differences there, too-- the iPad version of GarageBand is probably simpler in its features, and its UI is geared toward a touch screen.
