DCO 106 - A Roland Juno analog synthesizer model

New Roland Juno 106 synthesizer software model with extra effects
| @ 16 Sounds music production blog

Roland Juno 106

In 1984 Roland released a new six-voice analog synthesizer named Juno 106 as part of the Juno series Roland products. At the time an advanced programmable poly synthesizer easy to program.

In Greek mythology, Juno was a goddess and Jupiter's wife.

This is still an iconic Roland instrument from the 80's like Jupiter 8 and D-50.

New synth

Cherry Audio decided to make a model of the original synth with some modern add-ons. 
Like in a lot of other fields it is easier to sell something that people already know and with the number of new soft-synths released rebranding could be a selling point.

Does it sound like the original

When you make a model of a hardware synths users will expect it to sound like the original while most users have never played the original.
in the end, a lot of users do not care or know if it sounds like the original but it has to sound good and it does.

The synth plugin

In modern soft synth terms, this is a mid-range plugin modeled from a famous hardware design. In today's softsynths, it is not an advanced synthesizer but close to the original.

It is built around a digitally controlled oscillator with the usual waveforms, noise, a sub-oscillator, and envelope controlled filter- and amp. The sound is analog but digitally controlled. With the noise generator, it can do simple 80´s drums and percussion.

A synthesizer with a clear design and easy to program with a surprisingly wide range of sounds. A lot easier than the Jupiter 8 and D-50.


The original unit has up to 6 voices and this plugin has up to 16 but adjustable from 2 to 16 voices.
The voices can be set to Poly, Mono, or Unison with a detune spread for spreading like reese basses. This makes programming big pads with up to 16 keys and thick basses in unison mode easy.

A simple but great arpeggiator

The built-in arpeggiator is simple compared to other synthesizer plugins but still effective in collaboration with the Delay effect for interesting patterns.

Tempo sync

The original did surely not have tempo-synced parameters but this one does. 

The following can be synced to internal or external tempo/host tempo:

  • LFO
  • Arpeggiator
  • Delay effect

The filter

The filter is an important part of the variation in the sounds a synthesizer can produce.
Though it is not a Moog Ladder filter the primary filter is a resonant 24 dB lowpass filter that can oscillate and make divebombs if you turn the resonance to the max. It also has a secondary non-resonant high pass filter for filtering the bottom out when not needed.

The filter can be controlled by the envelope but the synth only has one envelope that the filter and amp can share. An extra envelope would have been nice but then the larger Jupiter 8 is the choice.

MIDI Learn

The synthesizer has an easy GUI midi learn system for setting up your hardware controller to control the plugin.
For each parameter, you can create a control with min, max, cc code, and curve. Min- and max sets the range for the parameter controlled. 

Along with the standard MIDI program change feature, this is great for both studio and live performance.

The synth Effects section

Like other synths, this is saved by the effects. Turn off all effects and you hear the simplicity of the design.

The plugin has 3 effects. The chorus from the original hardware and reverb and delay added by Cherry Audio.

The chorus effect

The chorus sounds like the famous Roland chorus that also has been modeled in a few plugins on their own. The chorus effect quickly became an iconic effect with its distinct dual-mode Roland sound.

TAL Sofware and others have made VST plugins of this chorus.

The original hardware synthesizer did not have a Delay effect but Cherry Audio decided to add one.

Delay parameters:

  • Tempo synced time
    • Standalone and host synced to tempo
  • Feedback
  • Damper
    • The delays are lowpass filtered to make it cut less through over time
  • Mix

Performance and CPU Usage

This is not a lightweight plugin but it has zero latency and reacts to midi program change making it useful for live performance. Cherry Audio might have modeled the individual components in the original synthesizer.
Compared to other synths, the CPU usage is in the higher end but it varies with the preset settings.

Pros and Cons

If you need an analog synth model from the 80´s, this plugin is a fair choice within most user's price range.

Presets and sounds

This synth is good for:

  • Pads
  • Roland character bass sounds
    • A different bass than Moog and DX7
    • With Number of voices and detune it can do fat basses
  • Arpeggiated sounds
    • Combining the arpeggiator and the delay can make interesting patterns
  • 80´s keys



  • Stand Alone version
  • Resizable window
    • Dynamic and not just in predefined jumps
  • VST3 support
  • Zero-latency
  • Preset browsing via midi program change
    • This makes it good for live performance use controlled from a hardware unit.
  • The low price ($25 on sale)
    • Even lower than Waves plugins



  • CPU Usage is a bit high
  • Amp and filter share the same envelope
    • This is a design choice but an extra filter-envelope could have been added

What are the alternatives to this synthesizer

Though this is a no-brainer for the price, there are alternatives.

  • The Roland Cloud version
    • Don't expect it to use less of your CPU
  • TubeOhm 106
    • Not that close to the original sound but still a fine synth
  • Some free Juno 106 model presets for Native Instruments Reaktor
  • TAL Software TAL-U-NO-LX Juno 60 emulation
    • TAL-U-NO-62 is a free version
  • U-he Diva can sound like this synth
  • Roland Boutique series hardware JU-06A
