The Intech Studio Knot is a compact MIDI host with MIDI jacks and USB. It allows you to connect a USB/MIDI controller, converting the data to MIDI jack out, or accepts data from MIDI jack in. The Knot is designed for use with Intech's own Grid controllers. Key features include an A/B switch to accommodate different MIDI jack standards (A-standard for Korg, IK Multimedia; B-standard for Arturia, Novation, Polyend) and the ability to merge jack MIDI in with USB MIDI in.
