Session 26: Pickup Machine Mastery — Loop, Overdub, Multiply

Objective: Go deep with Pickup machines. Master/Slave relationship: first loop sets length, subsequent Pickups sync to it. Multi-track live looping. Multiply (double the loop length and add new material). End with a 4-track layered loop performance from one external instrument.

Warm-Up (3 min)

You first met Pickup machines in Session 09. Session 25 introduced Track Recorders for capturing audio into the slot list. This session is the deep dive on Pickups specifically: layered looping, Master/Slave sync, and the Multiply gesture that doubles loop length on the fly. Press [PLAY] on a saved pattern. Imagine: 4 separate Pickup loops layering up, all synced, all overdubbing — a full performance from a single instrument input.

Setup

Start from a clean project (or an empty bank in your LAB project). Connect your external instrument (synth, guitar, mic, phone) to Input A/B on the rear panel.

Verify input levels: press [MIX] and check GAIN A/B is showing healthy signal without clipping. Press [NO] to close.

Set up the four Pickup tracks now:

• Track 5: Pickup (will be a Slave for textures)
• Track 6: Pickup (will be a Slave for bass)
• Track 7: Pickup (will be a Slave for melody)
• Track 8: Pickup (will be the Master — sets loop length)

For each: [TRACK N] → [FUNC] + [SRC] → set MACH = PICKUP, INAB = ON. [NO] to close.

Exercises

Exercise 1: Master Loop — Set the Length (5 min)

The first Pickup recording defines the Master loop length. This is the most important moment of a live looping session — get it right.

1. Set BPM to a comfortable tempo: [TEMPO] + Level knob. Try 90 BPM
2. Press [PLAY] to start the sequencer (silence — nothing programmed)
3. Decide your loop length. 8 bars is a good default for live performance (long enough to sit on, short enough to overdub responsively)
4. Record the Master: press [TRACK 8] + [REC1]. The TRACK 8 LED shows recording status
5. Play your foundational material on the external instrument for exactly 8 bars (count carefully — listen to a metronome via headphone CUE if you need it). Try a chord progression or rhythmic figure
6. After 8 bars, press [TRACK 8] + [REC1] again to stop. The loop immediately starts playing back. You should hear your 8-bar foundation looping
7. The Master's length is now locked. All other Pickup machines (Tracks 5-7) will sync to this 8-bar boundary

Exercise 2: Slave Pickup — Auto-Synced (5 min)

Slaves automatically match the Master's length.

1. With the Master loop playing on Track 8, set up Track 7 as a Slave Pickup
2. Press [TRACK 7] + [REC1] to start recording on Track 7
3. Play complementary material on your instrument — a counter-melody, a bass line, a different rhythm
4. Don't watch the clock. The Slave automatically stops recording when it hits the Master's loop boundary (8 bars). It then immediately starts playing back synced to the Master
5. Listen — Track 8 (Master) and Track 7 (Slave) loop together, perfectly in sync
6. Repeat for Track 6 (bass): [TRACK 6] + [REC1] to record. Play bass material for the 8 bars. Stops automatically. Plays synced
7. Repeat for Track 5 (texture): high pads, ambient drones, glitch sounds — anything you want as the textural layer
8. Result: 4 synced layers, all from the same single instrument input, all looping together

Exercise 3: Overdub on the Master (4 min)

Add layers to the existing Master loop. Overdubs are additive — they mix on top, no per-layer undo.

1. With all 4 Pickup tracks playing, focus on Track 8 (Master) — it currently has your foundational material from Exercise 1
2. Press [TRACK 8] + [REC1] to start overdubbing. The track LED indicates overdub mode (different from initial-record indicator)
3. Play additional material on the same external instrument — counter-rhythms, accents, additional notes
4. Each pass through the loop adds whatever you play on top of what's already there
5. Press [TRACK 8] + [REC1] again to stop overdubbing
6. The Master now has the original + your overdub mixed together. Listen
7. Important: there is no "undo last overdub" gesture. Each overdub commits permanently. This forces you to play with intention — a creative constraint, not a bug
8. To clear and start fresh: [FUNC] + [PLAY] on the Pickup track clears the buffer (firmware-dependent gesture; some require a different chord — check your manual)

Exercise 4: Multiply — Double the Loop Length (4 min)

Multiply lets you grow a loop by adding a section that's twice as long.

1. With your 8-bar Master loop playing, press [FUNC] + [UP] on Track 8 (or check your firmware for the exact Multiply gesture — sometimes it's a dedicated PICKUP MENU option)
2. The loop length doubles to 16 bars. The first 8 bars play back (your existing recording), and the next 8 bars are silence ready for overdubbing
3. Press [TRACK 8] + [REC1] to overdub during those new 8 bars. Play new material — a B-section, a verse counterpart to the original "chorus", etc.
4. Stop overdubbing at the 16-bar boundary
5. Now your Master is 16 bars long: bars 1-8 = original material, bars 9-16 = the new B-section
6. Slave Pickups (Tracks 5-7) remain at 8 bars — they loop twice under the Master's single 16-bar cycle. This polymeter creates a song-like build naturally
7. Use case: live looping into verse/chorus structure. Master holds a 16-bar A+B section, Slaves hold an 8-bar groove that repeats throughout

Exercise 5: Performance Move — Mute, Reverse, Stop (3 min)

Use the Pickup tracks as performance instruments after they're recorded.

1. Mute a Pickup mid-loop: [FUNC] + [TRACK 6] (mute Track 6, the bass). The bass drops out. [FUNC] + [TRACK 6] again to bring it back
2. Reverse a Pickup playback: [FUNC] + [TRACK 7] holds, then... actually the reverse gesture is firmware-dependent — try [FUNC] + [TRACK] on the playing track (per Session 09's exploration). The loop plays backwards
3. Stop a single Pickup without stopping the sequencer: [TRACK 5] + [STOP]. Track 5 stops; others continue
4. Restart it: [TRACK 5] + [PLAY]. Resumes from the loop start
5. Use scenes for live filtering (Session 19): build Scene B with closed filters and lo-fi on all Pickup tracks, slide the crossfader to morph the entire 4-loop performance through processing in real-time

Exercise 6: Save the Loops as Samples (1 min)

Pickup buffers are volatile. To preserve them across sessions, you need to capture them.

1. While a Pickup loop is playing, set up a Track Recorder (Session 25) with SRC = the pickup track number. Place a one-shot recorder trig
2. The captured Pickup loop is now in the Flex sample slot list — survives Project save/reload
3. Without this step, Pickup recordings are gone when you switch projects

Output Checklist

• I set Track 8 as Master Pickup and recorded an 8-bar foundational loop
• I set Tracks 5-7 as Slave Pickups, each auto-synced to the Master length
• I overdubbed at least one layer on the Master
• I used Multiply to double the Master loop length and added new material in the second half
• I performed mute/unmute and reverse gestures on the running loops
• I have a 4-track synced layered loop performance running

Key Takeaways

• Master sets the length, Slaves sync. The first Pickup recording defines the loop boundary; all subsequent Pickups conform
• Overdub is additive — no per-layer undo. Play with intention. Clear with [FUNC] + [PLAY] on the track if you need to start over
• Multiply doubles the length of the Master loop and creates space for new material in the new half. Slaves continue at the original length, creating natural polymeter
• Pickup loops are volatile — they live in record buffers, not in the slot list. Capture them via Track Recorder to preserve across sessions
• Pickup tracks behave like normal tracks once recorded — mutes, FX, scenes, reverse all work on them

Next Session Preview

Next: live resampling. Pickups capture external audio. Track Recorders can capture the OT's own output (MAIN). Set the recorder source to MAIN, place a recorder trig, and you've sampled your own performance. Slice it, p-lock it, mangle it — the OT eating its own tail.
