Roland Juno-60 midi kit

Last night I upgraded my Juno-60 with the MDCB60 midi kit from D-tronics. Even though I prefer not to use midi, there are situations where midi is nice to have, for example when doing quick sketches that you want to save, or try different sounds without manually having to play the same sequence over and over.

The DCB port

The Juno-60 was an upgraded version of the Juno-6, with the main difference that it had memory section, just like it’s main competitor Polysix. Another addition was the DCB port, which was Rolands predecessor to midi. Remember, this was back in 1982 and midi was first introduced in 1983. Before midi, Roland had DCB, Oberheim had it’s own proprietary protocol etc. Too my knowledge, only the Juno-60 and some of the Jupiter 8s had DCB . The JX-3P was the first Roland synth with midi, so DCB didn’t live more than a year or two. We should be thankful that the manufacturers actually managed to agree on the midi standard, that still lives 32 years later, even though it has its flaws.

Luckily, DCB is quite primitive and therefore simple to convert to midi. The MDCB60 only adds note on/note off, so there’s no pitch bend, program change, arpeggiator sync etc.


The installation was very straight forward:

  1. Open the Juno
  2. Remove the DCB-connector from the back
  3. Cut one zip tie so the DCB-connector reaches outside the synth
  4. Unsolder all wires
  5. Insulate the green and purple wires
  6. Solder the wires to the MDCB60
  7. Screw it to the back of the Juno-60
  8. Add a new zip tie
  9. Solder the wire from the MDCB60 to the gate pin on the Juno-60 board for 5V power

There’s a video here describing the installation, however, they seem to take the 5V power from another place than the gate pin.

The installation took less than an hour in total, and it worked straight away! I recommend this kit if you need basic midi on your Juno-60.

Roland Juno-60 & TR-626

Today I did a great package deal, bought a Roland Juno-60 & TR-626.

My Roland Juno-6 is one of my absolute favorite synths, and nothing I’d ever sell – but it has one “problem” – no patch memory. To be honest that isn’t exactly a show stopper –  it’s a simple synth, and writing down the settings on paper isn’t that hard. However, when a Juno-60 in about the same condition appears locally for the same price I paid for the Juno-6, “upgrading” to the Juno-60 was a no-brainer.

By incident, the guy was parting with all his stuff and also offered me a TR-626 as a part of the deal. To be honest, I don’t know what to do with it since I’ve got the heavy digital machines like the LinnDrum and Oberheim DMX, but it has actually grown on me. It actually sounds quite gritty and louder than the beige box suggests…
