Pass Slots

Pass Slots

A pass is one run of Loop 1, from its start to its wrap. Because Loop 2 is drawn at random, every pass sounds a little different. When one sounded good, you can keep that exact pass in a slot and bring it back later, without any randomness, by mouse or by MIDI note.

A pass slot is not a recording of audio. It stores which Loop-2 region (or silence) entered at which point of the pass, including the random choices as they were made, and the plugin replays that through its normal playback.

The pad bar: PLAY, SAVE and LEARN on the left, CLEAR ALL on the right, eight pads below

The pad bar

Control Meaning
PLAY Turns the chain on: all filled slots in order 1 to 8, empty ones skipped, repeating. Lit green while a slot or the chain plays; click it then to return to random playing.
SAVE Stores the last finished pass in the lowest free slot.
LEARN Learn mode for MIDI notes (see below).
CLEAR ALL Clears every slot. Cannot be undone.
Pads 1–8 Click a filled pad to repeat its pass. An empty pad does nothing.
x on a filled pad Clears that slot.

Workflow

  1. Let the plugin play randomly (Autoplay or MIDI mode) and listen.
  2. When a pass sounded good, click SAVE (it may already be the next pass that is playing; SAVE always takes the last finished one).
  3. Collect up to eight passes this way.
  4. Click a pad to repeat that pass, or PLAY to run through all of them in a chain.
  5. Click PLAY again to go back to random playing.
  6. Save the preset: the slots are part of it.

The last finished pass

The plugin always keeps the last finished pass: the most recent pass that ran completely while playing randomly. A stop, a transport jump or a MIDI gate-off in the middle makes a pass incomplete. SAVE is disabled when there is no finished pass, when that pass is already saved, when all 8 slots are full and while a replay is on. Only passes finished after the last preset or project load can be saved. Replayed passes are never recorded.

Replay timing

  • Every switch (pad, PLAY, back to random) takes effect at the next pass start, so a replay always begins at the start of Loop 1. Until then random playing goes on.
  • Pass starts lie on the song timeline: song position 0, then every Loop-1 length. A host loop that does not start on such a cycle start never completes a pass (nothing can be saved), and replay only (re)starts at cycle starts.
  • A transport jump or stop during a replay leaves Loop 2 silent until the next pass start; if PLAY was turned off meanwhile, random playing takes over at once.
  • Clearing the slot that is playing lets the current pass finish; then the plugin goes back to random playing (or, in the chain, to the next filled slot).

Plays what still fits

A slot stores only which Loop-2 region (or silence) entered when, as a fraction of the pass, and its mode (GATE or ONE). No audio, no effects, no mix, no REV: those come from the current settings. So after a tempo, bars or boundary change, the entries play at the same point of the pass, and an entry whose Loop-2 region no longer exists (or whose loop is gone) is skipped.

MIDI learn

The pad bar in Learn mode, a pad waiting for a note and other targets showing their notes

The 8 pads, SAVE and PLAY can each be bound to a MIDI note.

  1. Click LEARN. The strip says Learn: click a target.
  2. Click a pad, SAVE or PLAY. It shows ... and the strip says, for example, Waiting for note: slot 8.
  3. Play a note. It is bound to that target. Any note on any channel counts; velocity and length are ignored.
  4. Click LEARN again to leave Learn mode (a waiting learn is cancelled).

In Learn mode the pads show their note in a small label bottom-right, SAVE and PLAY show it as their text, and the pads' x is inactive. Clicking a waiting target again only cancels the wait (its note stays). Right-click a pad, SAVE or PLAY in Learn mode to remove its note. A note is bound to one target only: learning it again moves it. The tooltips name the bound note at any time.

A bound note acts like a click: a slot note repeats that slot (ignored while it is empty), the PLAY note turns the chain on (only while a slot is filled) or any replay off, the SAVE note saves. Bound notes also act while the host bypasses the plugin.

Learned notes describe your controller, so they are stored per plugin instance with the project, not in presets or banks. In MIDI mode a learned note no longer opens the gate; every other note still does.

Where slots are stored

The 8 slots are part of the preset: saving a preset stores them, loading one replaces them and turns replay off. The project stores them too. See Presets and Banks.
