A sixteen-step acid-box bassline sequencer that sends MIDI notes with gate, accent and slide per step.

| MIDI | 1 |
Each step carries a note, a gate, an accent and a slide, the pattern language of the acid box. An accented step leaves at velocity 118, which is above the accent threshold in Acid, and a slide step holds its note just past the next note-on, which Acid reads as a legato glide. Eight banks each hold their own pattern; the bank buttons choose which one plays and which one the grid shows. It drives any other MIDI instrument as well, so cord its MIDI outlet to a Sampler or a Rhizome too.
The grid
Drag in the note lane to set a step's pitch, which also gates it; right-click a step to rest it. The A and S rows toggle accent and slide. A slide into the same note ties it instead of striking it again. Right-click the A or S rows for Random, Clear, Nudge, Load riffs and Copy to another bank. Load riffs opens a browser over your Riffs library folder, with the ones you loaded before under Recent and Open a file for anything else. The riff you pick, or a file dropped on the grid, reads MIDI files and acid-box pattern dumps into the bank shown and the ones after it.
Parameters
| Transpose | Shifts the whole pattern in semitones. |
| SwingFollow | Follow makes the pattern take the patch groove from the transport instead of its own Swing knob. |
| Swing | Delays every second sixteenth, up to a triplet feel. Used only while Follow is off. |
| Gate | Length of a non-slide note, as a fraction of the step. |
| Velocity | Velocity of plain, non-accented notes. |
| Bank | Which of the eight patterns plays, A to H. |
| Nudge | Plays the riff that many steps later, or earlier below zero, wrapping around. The pattern itself stays as written, so it moves where a line lands against the kick without redrawing it. |
Recipe
| Acid line | Cord the MIDI outlet to an Acid. Draw a root note on steps 1, 4, 7, 11 and 14, an octave up on 8 and 16, accent steps 1 and 11, slide 7 into 8. Gate 0.5, Swing 0.2 with Follow off. Bring Transpose down by 5 for the breakdown. |
