X0X EXTENDED EDITION · LOCAL CONTROLS REVIEW

Copy a groove. Build a bridge.

New local candidate: block durations now reach 32 bars, and 303 A/B can use Scale adherence. Review and validation are local; no device has been flashed.

These captures come from the candidate's actual firmware UI running in the host simulator. They are not photographs of an installed build. Nothing on this page flashes or changes your FM-1.

Groove A → independent four-bar bridge → Groove B

SONG menu with DUP AS VARIATION highlighted — **1. Choose the source block**Open SONG with HOME twice. Use the BLOCK selector to choose the source row. Press SELECT to open its controls list and choose **DUP AS VARIATION**.

Duplicate block confirmation with SEL YES and HOME NO — **2. Confirm an independent copy**SEL confirms; HOME cancels. The copy gets independent patterns and recorded knob movements and is inserted immediately after the source. Later rows move down.

Inserted second block with pattern P3 on all five parts and BARS x4 — **3. Set the bridge length**The new row is selected. On the second SONG page, set **BARS x4**. This example shows P1 → P3 → P2: the P3 copy is now a separate variation.

Third SONG page showing arrangement enabled and length three — **4. Check the arrangement**The new third SONG page exposes **ARRANGEMENT**, degree metadata and active length. BARS is the selected block's duration; LENGTH is the number of active blocks.

EDIT BLOCK NOTES selected in the SONG menu — **5. Edit the copy's notes**This action selects the block's assigned patterns and returns to HOME. Choose a part and edit its steps.

Playing first block and a Q marker at the queued third block — **6. Queue a live change**The play arrow marks the current block. Q marks the requested destination. The jump occurs at the next musical bar.

Long sections: 1–32 bars per block

Actual firmware SONG page with BARS x32 — **BARS x32**With ARRANGEMENT ON, choose a block, turn SELECT to its second page, and set BARS with KNOB4. Duration follows the musical four-quarter bar clock, independently of lane lengths.

Native menu with 303A ADHERE set to SCALE — **303A / 303B ADHERE**Open the SONG controls list and scroll below the block actions to choose OFF, ROOT, CHORD or SCALE independently for each 303.

Native controls list showing KEY and SCALE — **Choose KEY and SCALE**Use SELECT to highlight the field and ALGORITHM to change it. These are the shared harmony key and scale; a generator's separate scale setting does not enable adherence.

A 16-step kick and a 5-step snare at straight sixteenths align again after 80 steps, or five bars. A four-bar block still ends after four bars; it does not wait for every lane to align. Unchanged instrument pattern numbers continue their phase across block boundaries. A changed instrument pattern number restarts that instrument's lanes. A long block repeats the stored patterns; it does not add 32 bars of unique note storage.

Scale-safe transposition

SCALE applies semitone transposition first, then selects the nearest note allowed by the shared key and scale and the instrument's existing note bounds. Equal distances choose the lower note. In C Ionian/major, C + 1 semitone resolves to C; C + 2 to D; C + 3 to D. This is semitone transpose with a final scale correction, not a new scale-degree transpose knob.

Scale adherence works with degree NONE and with ARRANGEMENT OFF. It covers sequenced notes and transposition, keyboard preview and incoming MIDI notes. OFF retains chromatic note output. ROOT and CHORD retain their existing chord-follow behavior when arrangement and chord degree are active. Stored source notes, generator settings, rhythm, accent and slide settings stay unchanged; slides retain their intentional continuous pitch movement between legal note targets. A range containing no legal note produces silence rather than an illegal pitch.

Existing projects retain their previous 1–8 bar durations. Projects using 9–32 bars or Scale mode require this candidate or a compatible newer version; older firmware rejects those settings. Keep a pre-change project backup for rollback. The packed model size and permanent RAM buffers remain unchanged.

Existing coarse MIDI CC mappings are preserved: the duration CC still selects 1–8 bars and the follow-mode CC still selects OFF/ROOT/CHORD. Use native/browser controls or the existing exact-value MIDI transactions for 9–32 bars and SCALE.

Remove a block, keep its patterns

Visible Undo: in the SONG controls list, scroll below 303B ADHERE to UNDO and press SEL. It uses the same history as HOME + REC; it undoes the latest recorded edit, not necessarily a deletion. Structural Undo requires stopped playback. HOME + PLAY remains Redo.

Stop playback. Open SONG with HOME twice, choose a row with the BLOCK selector, press SELECT and choose DELETE BLOCK. Confirm with SEL or cancel with HOME. Later rows close the gap; the nearest remaining row becomes selected.

Native SONG menu with DELETE BLOCK selected — **Delete the selected arrangement row**This action removes its place in the arrangement, including its duration, mute and degree assignments.

Delete confirmation says KEEP PATTERNS AND SOUNDS — **Confirm or cancel**All underlying patterns, sound and strip settings, presets and recorded automation remain available. Shared references keep working.

Arrangement after deleting its middle block — **Later rows close the gap**Prepared inactive rows shift too, so saved preparation is retained.

Undo restores the deleted middle block — **Undo with HOME + REC**Redo with HOME + PLAY. Structural Undo/Redo require stopped transport and use the existing bounded history.

SONG controls list with UNDO selected — **Visible UNDO menu item**Select UNDO and press SEL. The original shortcut remains available. Both restore the same complete history entry.

Arrangement after removing its final row — **An empty arrangement stays stopped**Deleting the final row leaves zero active blocks. PLAY and MIDI Start/Continue cannot accidentally play retained patterns while ARRANGEMENT is ON. Undo restores the row.

Review next: copy sequence data at the right scope

Proposed controls, not implemented in this deletion increment: sound presets remain shared. Per-block sound-preset snapshots are deferred in favor of the sequence editing you requested.

Scope	Proposed operation
One drum sound, such as the 909 snare	Copy its sequence lane and paste to the same sound in another sequence, leaving every other drum unchanged. Offer randomisation for that selected sound only.
One instrument pattern	Copy the entire 909 or 808 kit pattern, a 303 line or the BREAK sequence.
Whole block sequence	Copy all five instrument patterns together. DUP AS VARIATION already provides an independent new variation after the selected block.
Paste destination	Choose a new independent sequence or replace an existing sequence. Replacement must show the destination and warn about other blocks sharing it, with confirmation and Undo.

Lane copying should carry that sound's notes and supported timing and probability data. Kit-wide accent and swing must be handled explicitly so pasting one snare cannot silently change the kick or hats. Randomising one lane should keep its sound settings and every other lane intact. The exact randomisation choices remain for controls review.

Make the bridge musical

Choose EDIT BLOCK NOTES from the SONG list. It selects that block's assigned part patterns and returns to HOME. Choose 909, 808, 303A, 303B or BREAK and edit its sequence using the existing part controls. The duplicated patterns preserve the original groove's notes. Reassigning a part to an existing shared pattern deliberately links its notes again.

For example, alter the copy's snare and hat steps into a fill, or change its part mutes. In arrangement mode, the first five black keys on SONG toggle the selected block's five part mutes. Pattern assignments are available on the SONG knobs.

When ARRANGEMENT is ON, playback follows it even while you edit a part. To audition patterns outside the arrangement, stop and switch ARRANGEMENT OFF.

Section and button quick reference

Section / function	Controls	When
Open SONG	HOME twice from the main part view	Navigation
Select block	SONG: BLOCK selector	Chooses editing/start row
Copy independent variation	SELECT list → DUP AS VARIATION → SEL; SEL confirms, HOME cancels	Stopped; free pattern/motion capacity required
Change block duration	Second SONG page: KNOB4 BARS	ARRANGEMENT ON; 1–32 musical bars
Edit copied notes	SELECT list → EDIT BLOCK NOTES → SEL; choose instrument at HOME	Sound settings remain shared
Delete block	SELECT list → DELETE BLOCK → SEL; SEL confirms, HOME cancels	Stopped; patterns and sounds retained
Undo latest edit	SONG SELECT list → UNDO → SEL, or hold HOME and press REC	Structural history requires stopped playback
Redo	Hold HOME and press PLAY	Structural history requires stopped playback
Queue block	SELECT list → QUEUE BLOCK → SEL	Playing: next musical bar; stopped: choose starting row
Block part mutes	First five black keys on SONG	ARRANGEMENT ON

Control	Behavior
PLAY from SONG	Starts from the selected row and follows the arrangement. The arrangement wraps to its beginning after its last active block.
QUEUE BLOCK while stopped	Selects the starting block.
QUEUE BLOCK while playing	Jumps at the next musical bar, even if the current block has more bars remaining. A Q marks the queued row.
Duplicate / structural Undo / structural Redo	Require stopped transport. A pending Start or Continue also counts as busy.

What this increment preserves

The source block, its source patterns, timings, BREAK steps and recorded knob movements.
Later active rows and prepared inactive rows, including their chord-degree metadata.
One-step Undo/Redo of the complete copy. A rejected operation leaves the project and history unchanged.
The existing project format and audio processing.

Limits to review: Duration is 1–32 bars per row in arrangement mode. Blocks do not contain independent sound/strip/FX presets. The copy needs a default, unreferenced pattern bank and enough motion capacity; quiet prepared patterns are protected. Arbitrary reordering, section names, automatic bridge generation, FX ramps, individual-lane paste/randomisation and replace-existing-sequence controls are outside this increment. Physical Reason synchronization, listening and hardware timing remain to be tested after review and a separately approved flash.

This candidate is based on released 0.1.5-beta1. The separate autosave candidate has not been combined into it. Check the new test receipt for final validation; the prior deletion receipt remains preserved.
