Hi guys

Im kinda interested in getting one+ to be used as sound module for external keyboards. Got some questions

1) Does it support 2 usb midi controller via usb-hub? Lets call it midi controller A and B

2) can ya set track 1 to respond to both midi controller “all channel”, then track 2 respond to midi controller A midi channel 1, track 3 to midi controller B channel 1, etc??

Would be great to have 2 keyboards triggering different sounds

Thanks in advance! :worthy:

That doesn't work I'm afraid because of the infamous "Midi note off bug".
Yes, you can have different sounds playing from a MPC via Midi, but because of this bug, any notes that happen to be the same note number (say #60, C3) will make the second note stop sounding, as soon as you stop playing the first note. I.e. the first note (on ch#1) will send out a note off message, not on ch#1, but on all channels, meaning the second sound, on ch#2 will also stop playing at that moment.

Hence why, for me, all this shit that's going on right now is meaningless.
It's broken.
Period.
