Arpeggio
The arpeggiator is one of those simple features that ends up sparking whole ideas. Nils Frahm and others have relied on it for hypnotic, evolving patterns that work especially well with external effects. In JULY, we carefully recreated that original feel and added a few thoughtful updates: new play modes, an adjustable range of up to four octaves, bar reset, and extra control over rate, velocity, and note order. It keeps the instant, hands-on vibe of the classic, while giving you more room to shape and perform your own patterns.

VCF
The filter is a big part of what makes this synth feel alive. A 24 dB low pass with a gentle high pass in front, built around the classic IR3109 VCF chip.
It’s smooth and warm when you open it up, but it can bite when you add resonance.
We spent time making sure it moves and breathes like the real thing: soft when you need it, bright when you push it, so it always feels musical under your fingers.

BBD Chorus
Like other synthesizers of the early 1980s, this one includes a BBD-based stereo chorus that gives it much of its character. In JULY, the chorus circuit has been modelled in detail, including the MN3009 BBD chips with 256 stages each, the surrounding filters, and the LFOs that drive modes I, II, and I+II. A rate multiplier allows adjustment of the internal LFO speed, with the option to switch to the slightly different J6 values. JULY’s chorus also has a different texture compared to RES-09, our analog organ & strings machine emulation plugin.

JUNE includes a set of four high-quality effects, inspired by classic gear and designed to complement the synth’s character.
The effects section features:

• Tape Echo, based on our Space Echo emulation Outer Space
• Spring Reverb, adding classic vintage reverb
• Overdrive, for rich harmonic distortion inspired by classic guitar pedals
• Phaser, delivering deep, swirling modulation inspired by vintage analog phase shifters

You can rearrange the effects in any order using drag and drop.

The JUNO was released in 1982, expanding on earlier designs by introducing patch memory and a DCB interface while preserving its signature analog sound. It featured six voices, each built around a DCO with a suboscillator, a resonant low pass filter, a non resonant high pass filter, and the now iconic stereo chorus. Known for lush pads, rich chorused strings, and tight rhythmic arpeggios, it was embraced by artists such as The Cure, Eurythmics, Enya, and Animal Collective, among many others.
