Set it up with the very same Editor, store up to 8 presets and use it completely stand-alone in your computer-less setup. Click The Button 1 to 8 times to switch between presets on the fly, or hold it down to send an all notes off, reset or custom message to your gear.

No More Dongles

More and more synths, grooveboxes and controllers come with 3.5mm TRS MIDI ports. Midihub Mini speaks TRS MIDI natively, so you can connect them with simple stereo mini-jack cables. Midihub Mini uses the standard TRS Type A wiring. For gear with classic 5-pin DIN sockets, just plug in our Type A TRS MIDI adapter.

Midihub Mini in the Wild

Before launch, Midihub Mini went out to musicians and studios for a round of beta testing. Here's where it ended up.

The Editor & Pipes

Midihub Mini is set up with the very same Midihub Editor, so anything you learn on one works on the other. In the Editor you customize the processing logic by laying down pipelines made of Pipes, sort of MIDI effects, using intuitive Drag & Drop. Every pipeline starts from an Input or Generator pipe, from which MIDI data flows to the right, until it ends up in an Output pipe. All Midihub documentation, tutorials and presets apply to Midihub Mini as well.
