A performance editor and programmer for the Behringer TD-3, covering every color variant (TD-3-BK, RD, SR, AM, BU, WH…) plus the TD-3-MO. Program patterns on a fast piano-roll grid, generate 303-style acid lines in a tap, and send them straight to the hardware, or run the built-in sequencer with no device connected. Editing works while the pattern plays, so notes, accents and slides can be changed as it runs.
Single-octave piano-roll grid with piano-key pitch column and octave-selector rows, so the whole pattern stays on screen with no scrolling.
Note-name labels (C3, G3…) on every active note, with darkened sharp-note rows for easy tracking.
Per-step Accent and Slide rows, column-aligned with the 16 steps.
Numbered step header with brighter downbeats, 4-step group dividers and a red-glow playhead that lights every step as it plays.
Keyboard entry
Tracker-style two-row computer keyboard note entry (ZXCV and QWER rows), with , and . to shift the base octave across the three octave rows.
Left/Right move the cursor, Up/Down shift the note, Shift+Up/Down transposes the whole pattern. 1 toggles accent and the key left of Z toggles slide, both advancing the cursor as you type.
Transport
Play, Tap tempo, BPM and Steps, which you can click, drag or scroll to set. Step count snaps to 2/4/6/8/12/16.
Monitor button to audition notes, plus Group (I/II/III/IV) and Section (A/B) selectors.
Acid generator
RANDOM generates scale-locked 303-style acid lines with acid scales, octave hops, groove density, beat accents and glides.
TD-3 hardware
Full TD-3 MIDI SysEx control that works with every TD-3 color edition and the TD-3-MO, which share the same pattern protocol.
Auto-reconnect: connects the moment a TD-3 appears and goes offline when unplugged, with live MIDI port detection.
Explicit Backup (device to file) and Send (file to device), with a software fallback sequencer when no hardware is connected.
Studio
Synthtribe .sqs bank import and export, plus MIDI (.mid) export for a single pattern or the whole bank as one file per pattern.
AUv3 plugin and standalone app for AUM, GarageBand, Cubasis, Logic and any AUv3 host, with host tempo and transport sync.
Fully resizable editor that scales to fit iPhone, iPad and Mac.
