Author Topic: GR55 to trigger iOS app (korg iWAVESTATION) via Yamaha MD-BT01 Bluetooth midi  (Read 33 times)

Hi everyone.

I am new to this forum and have recently invested in a GR55, a Boss RC300 and a Godin xTSA ....  The MD-BT01 connects to my iPad Pro seamlessly and with very little noticeable latency so I would say so far, it is a great choice for midi.

I have set up a user patch on the gr55 which is essentially empty, to send a midi trigger from my godin, via the gr55, to my korg iWAVESTATION on iOS to trigger a bass and drum loop, which feeds into my rc300 via aux in.  That all works fantastically well and amazingly, given the nature of a loopstation, the timing is only limited by my lack of it!

So, here is my challenge......  I have set PC-TX on the gr55, so the trigger is sent, but that is at a system level, so when I change to my next patch on the GR55 and play my Godin, it continues to trigger the iWAVESTATION.  To circumvent this, I have to shut down the app on iOS before I change patches on the gr55. How can I switch off, or prevent other individual gr55 patches, sending midi commands?

As you can no doubt tell, im not too hot with midi (or the gr55) yet

TIA

You have 3 options

1. Change the guitar midi tx option from within the GR-55 menu.

2. place a toggling footswitch in-line with your midi cable to break the midi out circuit.

3. Use a midi device footswitch or midi command from your iPad to send system exclusive commands to switch the gR-55
 guitar midi tx option on/off.
