Our products are class-compliant USB MIDI devices.  You can connect multiple USB MIDI devices, including MIDI controllers, synths, and our pedals, but the system needs a single USB host to route messages between all of the devices.  For the studio or laptop-based performances, the computer acts as the host.  A tablet or smartphone with MIDI routing software can also be used.  For the iPad and iPhone, the Lightning to USB Camera Adapter will give you a USB port that you can connect to a USB hub.

Several companies make standalone USB MIDI hosts that allow you to set up a hardware-only system with no computers, smart phones, or tablets involved.  See this page for a list of supported MIDI hosts.
