Hi folks.
Firstly the setup...
Roli Keyboard, usb to mac for control. And Stereo out to Helix Return 3 and 4.
HX USB to Mac. (Although at the moment I'm listening directly to the HX on the Headphone socket)
Patch set to input from Return 3 and 4, sending to USB. (And have tried Multi)
All nice and quiet, I can play and record, all good. However, my wireless keyboard ran out of power earlier so I plugged it into another usb port on the mac and started getting loads of digital sounding crackly noise. Just testing I plugged in the track pad and got more noise.
How and why the hell is the HX or the Keyboard picking up digital noise from my keyboard and track pad? It's like the bad old days when on board pc sound picked up noise from your graphics card!
I have not had this problem at all before putting the HX in the loop, so is the noise coming from the very good quality balanced cables from the keyboard to the HX? It really is most bizarre, I wouldn't have expected any noise at all with this setup.
Any ideas?
Thanks.
