Session 23: Multiple Patterns, One Part — Pattern Variations

Objective: Build A01-A04 as four pattern variations all sharing Part 1: A01 = intro (sparse), A02 = verse (full beat), A03 = chorus (added melody), A04 = break (fills). Chain them manually using [PTN] + [TRIG]. The basic shape of a song using only one Part.

If you only have 5 minutes

On A01, hit [FUNC] + [RECORD] (copy pattern). Navigate to A02 (press [PTN] + [TRIG 2]). Hit [FUNC] + [STOP] (paste). A02 is now a clone of A01. Add some triggers, change a few. Chain A01 → A02 by pressing [PTN] + [TRIG 2] while A01 plays.

Warm-Up (2 min)

You learned in Session 22 that Patterns store triggers and Parts store sound. This session uses one Part across four patterns. The sound stays consistent — the triggers are what change. This is how a song gets sectional structure without sound shocks. Press [PLAY] on your current pattern. Picture: same sound, but here it has 4 hits, in the next section 16 hits, in the next section a totally different rhythmic feel.

Setup

Start from the LAB project with Part 1 saved (the verse sound from Session 22). Make sure you're on A01 (Bank A, Pattern 01) and currently using Part 1. The pattern should have a baseline groove with at least Track 1 (drums) and Track 2 (bass) active.

If you have multiple Parts saved, the OT may auto-switch when you switch patterns (Pattern → Part linkage is part of the Part Slot setting). For this session, we'll keep all four patterns linked to Part 1.

Exercises

Exercise 1: Set Up A01 as the Intro (3 min)

Strip A01 down to be sparse — the intro state.

  1. Make sure you're on A01: press [PTN], then [TRIG 1] to select Pattern 01 in Bank A
  2. Make A01 minimal:
    • Track 1 (drums): keep just kicks on [TRIG 1, 9] (half-time feel — kick on beat 1 and 3)
    • Track 2 (bass): single trig on [TRIG 1] with the root note p-lock
    • Track 3 (pad): trig on [TRIG 1] with long sample length — let it ring
    • Track 4 (hat): empty (silent — saved for verse)
  3. Press [PLAY]. This is your intro. Sparse, atmospheric, room to breathe
  4. Save the Project: [FUNC] + [PROJ] → confirm

Exercise 2: Copy A01 to A02 and Build the Verse (6 min)

Copy the pattern, then add density.

  1. With A01 active, press [FUNC] + [RECORD] to copy the current pattern to clipboard. The screen shows "PATTERN COPIED" or similar
  2. Navigate to A02: press [PTN], then [TRIG 2]. The pattern queues — wait for the boundary or press [FUNC] + [TRIG 2] to switch instantly
  3. Press [FUNC] + [STOP] to paste — A02 is now a clone of A01
  4. Build the verse: enter Grid Recording ([RECORD]) and add density:
    • Track 1 (drums): add kicks on every beat (1, 5, 9, 13). Add hats on offbeats (3, 7, 11, 15). Add a snare on 5 and 13
    • Track 2 (bass): add notes on [TRIG 1, 5, 9, 13] with pitch p-locks (root, third, root, fifth — see Session 14)
    • Track 4 (hat): add a basic 16th-note hat pattern
  5. Exit Grid Recording ([RECORD])
  6. Press [PLAY]. Hear the difference — A01 was sparse, A02 is full. Same sound design (Part 1), totally different density

Exercise 3: A03 — The Chorus (Add a Melodic Hook) (5 min)

Copy A02 to A03 and add a melodic element on top.

  1. With A02 active, [FUNC] + [RECORD] to copy
  2. Navigate to A03 (PTN + TRIG 3), [FUNC] + [STOP] to paste
  3. The hook: in Grid Recording, on Track 3 (pad), add trigs on [TRIG 1, 5, 9, 13] with PITCH p-locks creating a melodic motif: e.g., +0, +5, +7, +5 (a simple 4-note hook in your scale)
  4. Optionally boost Track 2 LEV in this Pattern? — wait, that's a Part-level thing. Volume changes are in the Part, not the Pattern. So if you want a chorus volume boost, do it via XLEV in a Scene (Session 20)
  5. Or via a single-step volume p-lock per trig (LEV is on the AMP page; hold a TRIG, raise LEV → that step's track plays louder)
  6. Press [PLAY]. A03 is your chorus — same density as the verse, plus a melodic hook on top

Exercise 4: A04 — The Break (5 min)

A04 is the fills/break section. Strip back, add detail.

  1. [FUNC] + [RECORD] on A03, navigate to A04, paste with [FUNC] + [STOP]
  2. Strip the drums: remove kicks except on [TRIG 1, 9]. Remove the snare. Keep hats
  3. Add fills on Track 1 in the last bar (steps 13-16): rapid kicks, snare rolls, or use conditional FILL trigs (Session 15) — hold a trig, set its CONDITION to FILL, so it only fires during fill mode
  4. Add a reverse texture on Track 3: hold a TRIG, PITCH p-lock to -64 (some firmware) or set the sample to reverse playback (firmware-specific)
  5. Press [PLAY]. A04 is the break — sparser drums, fill flourishes, ambient texture

Exercise 5: Chain the Patterns Manually (4 min)

Walk through your song structure live.

  1. Press [STOP]. Go back to A01 (PTN + TRIG 1)
  2. Press [PLAY]. A01 (intro) plays
  3. After 2 bars, press [PTN] + [TRIG 2]. A02 queues — at the next pattern boundary, it switches. The QUEUED indicator appears on the screen
  4. After 4 bars of A02 (verse), press [PTN] + [TRIG 3] to queue A03 (chorus). It switches at the boundary
  5. After 4 bars of A03, [PTN] + [TRIG 2] to queue A02 (verse return)
  6. After 4 bars, [PTN] + [TRIG 3] for chorus 2
  7. After 4 bars, [PTN] + [TRIG 4] for the break/outro
  8. The flow: A01 (intro) → A02 (verse) → A03 (chorus) → A02 (verse) → A03 (chorus) → A04 (break). 22 bars total
  9. Important: The Part is unchanged across this entire chain — the sound stays consistent. Only the triggers change

Output Checklist

  • A01 is a sparse intro version of the pattern
  • A02 is a full verse version with added density
  • A03 is the chorus with a melodic hook on top of A02's groove
  • A04 is a stripped break with fills
  • All 4 patterns share Part 1 (same machines, same FX, same scenes)
  • I chained A01 → A02 → A03 → A02 → A03 → A04 manually using [PTN] + [TRIG]
  • I saved the Project

Key Takeaways

  • Copy a pattern: [FUNC] + [RECORD]. Paste: [FUNC] + [STOP]. Standard OT clipboard verbs work everywhere
  • Pattern chaining: [PTN] + [TRIG N] queues pattern N to play at the next pattern boundary. Tightly synced section transitions
  • One Part across many Patterns = consistent sound, varied arrangement. The sound design stays put while the song shape develops
  • Volume changes per section belong in scenes (XVOL/XLEV) or per-step LEV p-locks — not in the Part itself, since the Part is shared
  • Section structure A01 → A02 → A03 → A02 → A03 → A04 is the bones of a typical pop arrangement (intro/verse/chorus/verse/chorus/break) — yours to refine

Next Session Preview

Next: multiple Parts for radical transitions. You've used one Part across four patterns — now we use Part 1 for verses (A01-A04) and Part 2 for choruses (A05-A08). Same triggers, different timbres, dramatic section contrast. Plus scene-driven transitions between Parts. A complete song in a single Bank.
