Sound & character

The JUNO-106 combines digitally controlled oscillators with analog filters and amplifiers. Saw, pulse, sub-oscillator and noise form the starting sound. Sliders keep the controls approachable; programs store the settings.

Model & versions

This dossier covers the original hardware. The JUNO-6 and JUNO-60 are distinct models; the JUNO-106 includes MIDI and 128 program memories. The contemporary Roland Cloud version is software, not vintage hardware.

How the sound works

Choose a section and discover what it does.

DCO

The DCO supplies the basic tone; pulse width, sub-oscillator and noise change the starting material.

What to check

Compare individual waveforms with chorus off.

Digitally controlled, analogue sound

DCO: PWM slider and manual/LFO control switch.

A DCO is not a sample player. Digital control stabilises pitch; waveforms and the following filters and amplifiers belong to the analogue sound architecture. Sawtooth, pulse, sub-oscillator and noise provide different ingredients for a patch.

Chorus adds space

Chorus I and II: two settings for a wider sound.

The built-in chorus has two modes. It widens the sound and changes how a patch sits in a mix. Compare the dry sound, chorus I and chorus II at the same volume, listening through both audio outputs.

Programs and MIDI

Program buttons recall stored sounds.

The 128 programs store your sounds. The MIDI Function switch controls which data is exchanged; mode III includes SysEx. A MIDI cable alone does not guarantee that an external editor can control every parameter. Check settings and back up before overwriting memory.

Recognise the versions

JUNO-6, JUNO-60 and JUNO-106 are separate models. Roland also describes JUNO-106S and HS-60 versions with built-in speakers. A Boutique JU-06 or Roland Cloud instrument is a later digital recreation, not an original JUNO-106. Assess the model label, connections and service history together.

Try listening yourself

A short listening exercise on the instrument. Use a copy of your sound and change one setting at a time.

  1. Choose a simple patch and disable chorus. Play a chord and change only the filter frequency.
  2. Compare sawtooth and pulse, then add a little sub-oscillator without changing other settings.
  3. Compare dry, chorus I and chorus II. Save your program before experimenting further.

An editorial exercise, not our own listening test or a built-in audio demo.
