Our modules are designed and made in Berlin.

For larger batches or established products we have an assembly partner, also in Berlin.

"Routes and merges midi data between two USB devices and one TRS midi device.

USB Bridge A features two midi USB hosts and conventional TRS midi (type A) input and output.
Midi data is routed between the connected devices and merged if necessary. Routing is very fast with very low latency.

Data received from a USB device will be send to the other USB device and to the TRS output.
Data received on the TRS input will be sent to the two USB devices.
Depending on the kind of data it will be merged, see below.

You can use this to:

Connect one or two midi USB midi controllers/keyboards to a conventional midi device
Connect a keyboard to a module with only USB device capability
Connect a cheap USB midi interface and get more conventional midi IOs
Use your phone to control your Eurorack or as a synthesizer
Connect a synthesizer via USB"
