The JU-06A adds JUNO-60/106 switchable filter behaviour, continuous HPF, and performance extras (arp, chord, sequencer).

Why does chorus matter so much?

The JUNO chorus is half the instrument’s identity — two interlaced delay lines that widen and thicken without a second synth.

Different swirl intensities/rates in the classic JUNO sense — II is often the thicker ‘record’ wash. A/B on a held chord.

JU-06A

The ‘80s pad and bass machine everyone still wants — continuous HPF of the 106 plus PWM envelope of the 60.

DCOs, high-pass + low-pass, legendary chorus, arpeggio and chord memory.

DCO RANGE · LFO · PWM: Detune and pulse motion before the filter.
HPF: Continuous high-pass — the 106 trick for thinning pads.
VCF FREQ · RES · ENV · LFO · KYBD: Classic JUNO low-pass voice.
CHORUS: I / II — adjustable swirl that defined ‘80s records.
ARP · CHORD · SEQ: Performance tools the vintage panels lacked in this form.

Glass pad with chorus II
Open LP, gentle HPF, long ENV, Chorus II — the classic wash.
1. Init a soft saw/square mix on both DCOs.
2. HPF ~20–30%, VCF FREQ mid-high, RES low.
3. ENV: slow A/R, high S. Enable Chorus II.
4. Hold a triad; add LFO → PWM for shimmer.
Plucky JUNO bass
Closed filter, short ENV to VCF, subby DCO range.
1. DCO 1 square, DCO 2 saw down an octave if available.
2. VCF low, RES ~40%, ENV MOD strong, short decay.
3. Chorus off for mono punch; on for disco thump width.
Arp stabs
Chord memory + arp for ‘80s gated patterns.
1. Store a triad in chord memory.
2. Arp up/down, 1/16, moderate gate.
3. Ride VCF with the envelope for accents.
HPF thin-out under a kick
Continuous high-pass so the JUNO leaves floor for drums.
1. Start with a full pad (Chorus II on).
2. Raise HPF until the kick punches through a TR-08/09 loop.
3. Save as ‘pad under kick’ — mix glue is a patch, not only a fader.
60 vs 106 filter flip
A/B the JU-06A’s switchable filter personalities on one riff.
1. Write a simple bass + chord stab.
2. Flip 60/106 behaviour; keep cutoff and reso fixed.
3. Note which mode ‘sings’ vs which stays polite — pick per song.
