It's been a while since my last post, AND some time since I've last tried to hook everything up right. I guess with all tech, there will always be one thing that causes trouble!
OK. So, here's my rig:
iMac running macOS Mojave (10.14.1)
Motif-Rack XS Editor version 1.6.7 (setup screenshot below)
Arturia Keylab 88 connected via USB and MIDI
Motif Rack XS set to USB mode
TC Helicon VoiceLive2 connected via MIDI
iConnectMIDI4+ with routing setup as follows:
iPad4 connected to front port via proprietary lightning to USB-A port cable (stand-alone mode [not connected to iMac])
5-pin DIN cables running from KL88 Out to iCM Port 4 In, VL2 In to iCM Port 3 Out, and XS MIDI In to iCM Port 2 Out
Using BandHelper app on iPad to send MIDI messages to various ports
I think that covers it...
XS Rack communicates perfectly with XS Editor
KL88 communicates perfectly with XS
BandHelper can send program changes through the iConnectMIDI4+ to the VoiceLive2, but not the XS Rack when in USB mode (MIDI mode works fine).
Please let me know if I forgot to specify anything!
