ACID

ACID is a 303 line: one note a step, each with its own octave, and an ACCENT, a SLIDE into the next note or a TIE that holds the one before. It plays on part 3, LINE, so you can make a line, leave it playing and go to RUDIMENT.

Writing a line

Stopped, arm REC: the keys become a 303's pitch mode. Each key you press writes the next step's note and moves on, from step 1, and you hear it. OCT+ and OCT- shift the keyboard for a high or a low note, SEQ puts a rest in the step, and SEQ with a key still down puts a TIE there, so the note before holds on. Tap REC again to finish. The step the next key writes breathes on the white keys.

Stopped and not armed, the white keys are the line's steps. Tap one to turn its step on or off (a new step takes the note you entered last). Hold one to edit that step:

Each note you set this way is heard. The keys of the held step's marks light while it is held. Past 16 steps, the two black keys past C5 page the white keys with nothing held (Step pages).

Playing it

Press PLAY. A key pressed while it plays transposes the whole line from ROOT, as a 303's transpose does: C4 (with ROOT C) puts it back. Hold SEQ while it plays to edit the steps again.

MAIN holds LEN, the line's length (the SEQ page's), ROT, which turns the whole line round a step at a time, notes and marks together, TRN, which moves it along the scale by degrees, and OCT, which moves it by octaves. TRN, OCT and the keys' transposition change what plays, never the notes you wrote. A project keeps the line with its ROT, TRN, OCT and the LINE it was drawn from.

ALGORITHM writes a line for you, LINE 1 to 99, with the same writer as LINES: on the LINE page DENS sets how many steps play and SPAN how many degrees the line uses. DENS and SPAN are shared with LINES. The first edit you make by hand keeps the line as it is (the toast says KEPT), so DENS and SPAN never write over your edits. REC held to its first ring undoes a line written over yours.

FLUX, on the LINE page, moves the line as it plays: each step, with chance FLUX, its note moves a degree or two along the scale or an octave, or goes back to the note you wrote, or its ACCENT or SLIDE flips (one change in eight each), and it stays that way pass after pass. Turn FLUX to 0 to keep the line as it plays now; PLAY from stop starts from the line as written. The steps you wrote never change. With QNT CHORD on SCALE, the line bends to the nearest note of the chord PLAY sounds, and TRN moves it along the chord.

ACID on ANALOG, the first time, plays ANALOG's ACID sound with VCE on LEGATO, so a SLIDE glides into the next note without a new attack; GLIDE on the GLIDE page sets how long it takes.

ACID is not on the default wheel: pick it on the PAIR page (hold HOME, tap GLO, KNOB 2) or give it a black key with the slot picker (The wheel). It plays on part 3, which it shares with LINES, ALIVE, TONNETZ, ENIGMA, S+H and CANON.

Where it comes from

The steps follow the Roland TB-303's: a pitch, an accent and a slide each, written in pitch mode. The line writer is LINES' own, after the TB-3PO idea in Hemisphere (LINES). All of it is written fresh for SQRL-1 (firmware/src/shell.c, databurn, MIT).
