Kenton Thru-25 is a 1in / 25out MIDI thru box for splitting MIDI signals. The signal at the MIDI input is distributed in parallel across 25 MIDI Thru jacks. The Thru-Box works reliably with ALL MIDI messages including Clock, SysEx, MTC etc. The latency is less than 1 microsecond, it is an active device, which is not powered by the MIDI line, but by an included power supply.
