Trackmo '91 Features
A 4-track Amiga tracker that runs as an instrument plugin (VST3 and AU), in time with your DAW.
The Amiga sound
- ProTracker 2.3D's own replayer, ported from pt2-clone. Every register write was checked against pt2-clone's.
- Four Paula voices with band-limited output, through the A500, A1200 or RAW output stage and the LED filter, on a PAL or NTSC clock.
- PAULA 14-BIT switch: the noise floor drops from about 50 dB to about 86 dB below full scale.
- Stereo: the Amiga's hard left-right-right-left, or PC-style 50 % width.
In your DAW
- SONG sync locks the song to your timeline, so locating, looping and offline bouncing all give the same result.
- PATTERN sync launches patterns from MIDI notes (C3 = pattern 00). The next pattern takes over when the current one ends.
- Four stereo outputs. Each track can feed any of them.
- MIDI out per track: the notes, plus pitch bend that follows slides, vibrato and arpeggio. Tracker patterns can play your other synths.
- MIDI in: play live and record straight into the patterns, snapped to rows (QUANT) or with the original timing kept (TICK), and optionally with velocity.
- Everything saves with your project.
Tracking
- A ProTracker-style editor on a real Amiga screen. It works from the keyboard and has four colour themes.
- Copy and paste blocks to and from OpenMPT, Schism Tracker and Furnace.
- Opens MOD, XM, S3M and IT. Songs with more than four channels go through a channel picker. Samples are retuned so every note stays in tune.
- Exports a plain .mod. PT-SAFE tells you whether a real Amiga will play it unchanged.
Samples and breaks
- Import WAV, AIFF or FLAC at the note you choose. FIT re-imports a file that was too long, at the note that keeps all of it.
- Beat slicer: AUTO-SLICE finds the hits, MAP TO KEYS plays them from your keyboard, and WRITE TO PATTERN stamps the break into a track. Also GATE, ALIGN 9xx and SLICE TO SAMPLES.
- Sample editing: loop points with drag handles, crop, cut, reverse and fades.
The Amiga synth
- AHX / HivelyTracker instruments in any slot. They match HivelyTracker frame for frame. Loads .ins, .ahx and .hvl files.
- An instrument editor for the envelope, filter and pulse-width sweeps, vibrato and the performance list.
Beyond AHX (new in 0.8.1)
- A resonant filter that can follow the envelope, velocity, an LFO or the mod wheel.
- An LFO on the filter, pulse width or wavetable.
- A fixed 50–200 Hz clock, so instruments keep their speed at any tempo.
- Wavetables from any WAV file.
- 40 factory presets: basses, leads, pads, keys, stabs and drums.
- RENDER TO SAMPLE turns any instrument into a plain sample. Exported .mods carry it that way.
Shout Outs
- pt2-clone by Olav Sørensen (8bitbubsy)
- ProTracker 2.3D by Lars Hamre with Mushroom Studios/Noxious.
- HivelyTracker by Pete Gordon for the basis of the synth engine.
- Antti S. Lankila, whose measured A500/A1200 filter values drive FILTER = MEASURED (the default), via OpenMPT/libopenmpt.
- OpenMPT / libopenmpt for MOD format details, the clipboard format (read from its source), and the reference we test against.
