TDminator TD-3 AUv3 Synth

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

AUv3 + STANDALONE
Run TDminator standalone or as an Audio Unit v3 in AUM, GarageBand, Cubasis, Logic and other AUv3 hosts. Load it as an instrument to hear the 303 Devil Fish bassline, or as a MIDI effect to drive the TD-3 or another synth. Tempo and transport follow the host, and the editor resizes to fit iPhone, iPad and Mac.
