Starter recipes

  • New Wave glassy pad

    Detuned DCOs, slow filter, chorus.

    1. Detune DCO 2 a few cents.
    2. Long amp ENV, mid cutoff.
    3. Chorus on; LFO slow to PWM if available.
  • Soundtrack bass bed

    Stable digital oscillators under a dark filter — film-cue low end.

    1. Both DCOs down an octave feel; slight detune.
    2. Cutoff low, RES modest, slow filter ENV.
    3. Long amp release so notes bloom under picture cuts.
  • PG-style preset rewrite

    Pick a factory vibe, then rebuild it from init so you own the architecture.

    1. Audition a favourite factory patch once.
    2. Init; recreate wave mix, filter and ENV from memory.
    3. Compare — the gap is your next Manual chapter.

FAQ

Why include JX-03 next to JU-06A?
Same Boutique ecosystem and era, different oscillator story — digital DCOs vs JUNO’s DCO+chorus identity.
Does ‘digital DCO’ mean cold?
Stable pitch, yes; cold, no — the analog-style filter and chorus still do the warmth. Stability is a feature for layered live rigs.
