MIDI THRU is an active 1 to 5 midi multiplier with 3.5mm jacks.

Nowadays many devices have TRS jacks for their midi inputs & outputs.

For these you need 3.5mm stereo jack plugs to MIDI DIN 5-pin adapters if you want to use regular midi cables. Also most midi tools are only available with classic MIDI DIN jacks.

This is where MIDI THRU comes in, as you can connect your TRS MIDI devices directly without the need for adaptor cables.

There is one MIDI input which is switchable by means of a push button from.


(The new standard, Korg, Make Noise, AKAI)


(Arturia, Novation, 1010 music)

The input signal is actively multiplied to 5 TRS type A outputs.An led indicates if a midi signal is being processed, MIDI THRU is powered via USB C (cable not included).

Since it is an active device it can only be used in one direction. Therefore the outputs cannot be used as inputs.

If you need a simple TRS-A to TRS-B adapter check out the ST Modular – TRS Switch.
