TDminator TD
Read full descriptionHide full description
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.

2099 Techno writes complete tracks. Press generate and you get 76 bars with an intro, builds, two main sections, a breakdown and an outro, played by a virtual-analog engine and a 909-style drum machine. Bass, acid, stabs, pad, a lead line and the kit, through a dub delay, chorus and reverb. Nothing is sampled. Every note is made on the fly and no two tracks come out the same. The music comes from chaos maths. Three Lorenz attractors shape the melody, the rhythm and the mood. Three separate logistic maps run underneath the drums, the bass and the acid line, so they wander independently: turn the logistic control down and the hats and perc repeat every bar, turn it up and they never do. Chaos on its own is noise, so a small model filters it. It gets rewarded for consonant intervals and rehearses two hundred notes over the changes before it writes anything. The CHAOS / TASTE slider decides how much say each one gets. Eight styles, and they are properly different. Detroit rolls an off-beat bass under syncopated stabs. Dub Techno holds one chord for four bars and lets the delay do the work. Acid runs a 303 line with slides and accents. Hard pushes past 140 with a Reese bass and the drive up. Minimal takes most of it away. Every track is built from its seed. Write the seed down and you can have that exact track again, note for note, whenever you want it. You can play over it, too. The pads are the notes of the track's key rather than a piano keyboard, so nothing you touch is wrong, and the sixteen-step lane runs in time with the track and follows your host. Both play any part you like: bass, acid, stabs, pad or lead, through that part's sound and out on its MIDI channel. Choose which sections the lane plays in - just the breakdown, say - and preview it on its own without starting the track. Turn on RADIO and it keeps playing, picking a new key, mode, style, sound kit and tempo for each track. You also get: • 8 styles, 6 dark modes, 12 keys, tempo and density • Two-oscillator analog voice with sub, noise, resonant filter and glide • 22 presets and 9 sound kits, from Warehouse to Game Boy, plus random patch • Six-part mixer, dub delay, chorus, plate reverb and a global sweep filter • A PLAY panel: pads in the track's own key, and a 16-step lane with accent and slide, running in time with the track and only in the sections you pick • MIDI in, so your keyboard plays whichever part you have selected • MIDI export: six tracks, one per part • Live spectrum, waveform and a view of the chaos engine at work Two Audio Units, an instrument and a MIDI processor. Each part sends on its own MIDI channel, drums on 10, so one instance can drive six instruments. The MIDI version passes your keyboard through instead of swallowing it. Both follow your host's tempo and transport. One install registers both. The app is free and nothing in it is held back. Using the Audio Units inside other apps is a one-time purchase, and each AUv3 session plays for two minutes first so you can try them properly.

Verdict
