Here’s a DIY method for connecting two USB hosts together to send/receive USB-MIDI between them. > [@Prost! diy device for connecting 2 midi hosts](https://forum.critterandguitari.com/t/prost-diy-device-for-connecting-2-midi-hosts/5843): > > [Prost!](https://github.com/frederickk/prost) uses Arduino Pro Micros as intermediary to allow Midi host to Midi host communication. Prost! uses 2 [Pro Micro](https://www.sparkfun.com/products/12587) boards (or any compatible board or clone with an [Atmel 32u4 chip](https://www.amazon.com/s?k=32U4&i=electronics&ref=nb_sb_noss_2)) connected serially (TX/RX) in order to pass USBMidi data. Here’s a [demo video](https://www.youtube.com/watch?v=BwLtm9UBdX8) with [Ableton Live](https://www.ableton.com/), an [Organelle](https://www.critterandguitari.com/organelle), and [Norns/Fates](https://llllllll.co/t/fates-a-diy-norns-dac-board-for-raspberry-pi/). If you’re interested in building your own, check out the [Github repo with all you need to get up and running](https://github.com/frederickk/prost). Longer demo on [YouTube](https://www.youtube.com/watch?v=BwLtm9UBdX8) For now I’m using a simple protoboard, while I fu… Haven’t tried it but looks promising! --- _[View the full topic](https://forum.critterandguitari.com/t/usb-midi-connection-between-two-usb-hosts/2050)._
