Roland Juno-6

Find out how you can control your Roland Juno-6 with MIDI using Kenton MIDI Retrofit Kits or MIDI to CV converters

The Juno-6 does not have MIDI or CV/Gate. It does however have an Apeggio Clock In 1/4″ jack socket. Kenton offer a variety of options for your Juno-6.

  1. Fit a MIDI Retrofit Kit
  2. Clock the Arpeggiator

Fitting a MIDI retrofit or socket upgrade kit is a skilled job which should be undertaken only by a competent synth service engineer or fitted by us at our premises in Epsom, near London (UK customers only).

1. Fit a MIDI Retrofit Kit to the Juno-6

You can fit a MIDI Retrofit Kit which will allow you to control the Roland Juno-6 directly using MIDI from your DAW, MIDI Sequencer or other MIDI controller. Our MIDI Retrofit Kit adds MIDI IN and THRU sockets.

With the Retrofit Kit you’ll have MIDI control of Notes, Pitchbend, Modulation, Filter cutoff, Portamento / Glide, Sustain. You will also be able to clock the arpeggiator using the MIDI clock. Note that the retrofit is MIDI IN and THRU only, there is no MIDI Out.

2. Clock the Arpeggiator

You can use one of our MIDI converters to clock the Juno-6’s arpeggiator using MIDI clock.

Which products do I need?

The following MIDI converters all have clock outputs, so can be used to clock the Juno-6’s arpeggiator:

USB Solo (not currently available)

Modular Solo (not currently available)

Pro-2000 MkII (not currently available)

You will need 1 x 3.5mm to 1/4″ jack cable to connect the converter to the Arpeggio Clock In socket on the Juno-6.

Connecting the MIDI converter

Use the following output on each MIDI converter:

Modular SoloClock 1 or Clock 2
Pro-2000 MkIIClock Out
Pro-DCB Mk3Clock Out

MIDI Converter settings

You will need to set the Clock Divide Ratio, Clock Polarity and Continue = Start parameters on the MIDI Converter.

The MIDI Clock runs at 24ppqn (pulses per quarter note). The Juno-6 will play one note per pulse, so you will need to set the Clock Divide Ratio to play notes at your desired speed.

Clock Polarity should be set to positive. Some of our converters have a dedicated polarity setting, others use Maximum and Minimum Values to set the polarity.

Continue = Start should be set based on how your sequencer. Some sequencers, rather than sending a MIDI Clock Start message, send a Song Position Pointer = 0 message followed by Continue. When turned off, Continue messages will only be treated as Start if immediately preceded by a Song Position Pointer = 0 message.

The table below explains which parameters to set on your MIDI Converter:
