Hi - I have a keyboard rig with redundant backup via KVM switch and a Radial SW8-USB. I need to send the Expression device data to two computers (Mac Minis) at the same time. I'm assuming I can connect the MIDI expressions to the KVM switch and it will send to both rigs... anyone have experience wit...

Indeed, very frustrating. This model came out only 2/3 years ago, and costs $1500USD. Thanks for the advice, I guess I'll order the iO version.

Ah, got it.

Yes, there is a USB-to-device port on the front that's USB-A. I think it's is only for audio/MIDI file playback/storage. The manual says the port supports USB flash drives, hubs, and wireless LAN adaptors. I'll give it a shot. And in the meanwhile, I'll check to see if anyone else has had luck conne...

If I want to operate more pedals, would the iO expression device do the tr...

Thanks Rob... I'll let ya know how the pedal works out!

Hi all, I've been trying to use this BOSS pedal for MIDI expression, and I'm having troubles with erratic controller data. I'm not sure if it's the pedal itself, or my connection. I'm currently using a regular 1/4" patch cable in the 'expression' port. The pedal is supposed to be dual-purpose a...

WOW!! This looks fantastic! The original device was a game-changer in my field of work, and now you've done it again. Congrats Rob!
