Midithrone is an active converter which allows you to connect any MIDI USB Class Compliant device to any other MIDI device with a DIN (traditional) or ⅛” MIDI input. Anything from a 1982 Juno Synthesizer, to a 2023 Opsix, can now connect over MIDI to your USB MIDI controllers.
Midithrone has 2 MIDI outputs. The first is a traditional 5-pin DIN MIDI jack. Connect this jack to any MIDI device with a similar old-school DIN MIDI INPUT.
The second output is a new-school ⅛” MIDI jack, which can be set to comply with either TYPE-A or TYPE-B standard (secret switch inside).
All MIDI messages including note on/off, transport (clock, stop and start), program changes, sysex etc are transmitted without modification. Midithrone does no filtering or modifications to the messages what-so-ever, and simply passes on MIDI messages from the USB device out through the hardware MIDI ports.
 
To power Midithrone, use a USB-B cable to connect to any 5V USB power supply, such as a phone charger or other USB power source. A USB battery bank can also work well.
