Version 2.0 adds a built-in 303 Devil Fish bassline, so patterns play with or without a TD-3. Switch patterns from MIDI and start from a 64-pattern factory bank.

TDminator is a pattern editor and 303 bassline for the Behringer TD-3, every color variant (TD-3-BK, RD, SR, AM, BU, WH…) and the TD-3-MO. Program patterns on a piano-roll grid, generate 303-style acid lines with one tap and send them to the hardware. With no TD-3 connected, the built-in 303 Devil Fish bassline plays them.

Patterns can be edited while they play: notes, accents and slides change on the next pass.

303 DEVIL FISH BASSLINE (NEW IN 2.0)
• Built-in Devil Fish voice, modeled on the TD-3-MO, with its own hardware-style panel
• Cutoff, Resonance, Envelope, Decay, Accent, Tune, Wave and Volume, plus the Devil Fish extras: Accent Decay, Normal Decay, Soft Attack, Slide Time, Filter FM, Filter Tracking, Sweep Speed, Sub Osc, Overdrive and Muffler
• 13 programs, with values shown on a red dot-matrix display
• 303 half-step gate with slides held into the next note
• Monitor menu: play the internal bassline, the TD-3, both, or mute

PIANO-ROLL PATTERN GRID
• Single-octave grid with a piano-key pitch column and octave rows, so the whole pattern fits on screen
• Note names (C3, G3…) on every note, with accents and slides shown in their own colors
• Accent and Slide rows aligned with the 16 steps
• Numbered step header with 4-step group dividers and a playhead that follows the sequencer
• Ties are kept on load and Send, and the sequencer holds tied steps
• On iPhone, a 303 / SEQ button switches between the bassline panel and the grid

KEYBOARD ENTRY
• Tracker-style note entry on two rows of a computer keyboard
• Arrows move the cursor and shift pitch, Shift+Up/Down transposes the whole pattern
• Accent and slide keys advance the cursor as you type

TRANSPORT & CONTROLS
• Play, Tap tempo, BPM and Steps: tap, drag or scroll to set values
• Step count snaps to 2/4/6/8/12/16
• Group (I/II/III/IV) and Section (A/B) selectors
• RANDOM generates scale-locked acid lines with octave jumps, accents and glides

MIDI PATTERN SWITCHING (NEW IN 2.0)
• Program Change 0-63 selects one of the 64 slots, numbered like the TD-3
• Notes from C1 upward on MIDI channel 16 also select slots, so a DAW clip can trigger patterns
• While playing, the switch waits for the current pattern to finish

FACTORY BANK (NEW IN 2.0)
• 64 acid patterns ready to play out of the box
• Browse imported banks without a TD-3 connected

WORKS WITH YOUR TD-3
• Full TD-3 MIDI SysEx control for every TD-3 color edition and the TD-3-MO, which share the same pattern protocol
• Connects as soon as a TD-3 appears and goes offline when it is unplugged
• Backup (device to file) and Send (file to device), so nothing is overwritten without asking

IMPORT & EXPORT
• Synthtribe .sqs bank import and export
• MIDI (.mid) export of one pattern or the whole bank, one file per pattern
