I have two keyboards connected to my iMac and want to assign different software instruments to each keyboard so I can play two different sounds on two different keyboards. My setup: 1. My first keyboard is a Roland FP-7 masterkeyboard connected to a M-Audio ProFire 610 Firewire-Audio-Interface which goes, guess what, to my iMac via Firewire. 2. My controller keyboard is a AxiomPro 61 which connects to my Mac via USB. Right now, both keyboards show in Logicâ€™s environment, both always play the same instrument and both are fully functional in Logic (the Axiomâ€™s HyperControl is perfectly working as well, i. e. installed correctly.) Now, what I want to do is, tell certain software instruments, I want to play them on my Axiom or my Roland. I tried several tips on the internet, changed the MIDI channels of both keyboards and changed the corresponding MIDI channels in Logicâ€™s tracks â€“ still: both keyboards play exactly the same. My guess: Is there anything I have to do in the environment? Right now, I have a basic setup, I assume, with my Axiom, my ProFire Firewirebox and the Caps-Lock-Keyboard on the left. Then it goes to the keyboard and so onâ€¦ Could someone please give me a step-by-step instruction, how to set this up? Thanks so much.
