StormDJ is a DJ program for fast Amigas: two decks, a mixer with a three-
band EQ per deck, a crossfader and a headphone output to pre-listen to
the next track. It plays MP3, AAC (also HE-AAC, .m4a), Ogg Vorbis, FLAC,
WAV, AIFF and 8SVX files and tracker modules (Protracker, OctaMED,
Oktalyzer, XM, S3M, IT and many more).
This is a beta release: StormDJ has been tested on only a few Amigas
and emulators so far. Please report problems to hakke@gmx.de, with your
CPU, OS and MUI versions and sound hardware.
Features
--------
- Two decks: play, cue, restart, position bar, pitch (+-8, 16 or 50%)
with a Reset that can glide back over a few seconds.
- Sync: one click matches a deck's tempo to the other (also at half or
double tempo). Beat Sync also lines up the beats, within a few ms.
- Tempo analysis in the background, BPM ranges for fast music, a 2x
button for a halved BPM, Tap.
- Nudge and Hold, like a hand on the record: 4% slower or faster, or
stopped, while a button or function key is held (F1-F5 for deck A,
F6-F10 for deck B, like the buttons of a hardware player).
- Turntable effects: Brake, Backspin and Slow start, timed in beats or
seconds.
- Keylock: change the tempo, keep the pitch (modules change their tempo,
other formats are time-stretched).
- Stereo width per deck; Amiga modules start narrower (adjustable).
- Mixer: three-band EQ per deck with kill switches, channel faders with
level meters (adjustable fall, peak marks), master and headphone level
with meters, cue/master blend, crossfader.
- Headphones: pre-listen on a second output (AHI unit or Paula), or
split one output into master left and cue right. On a PiStorm the
Pi's audio jack can be that AHI unit, with Emu68PWM from Aminet
(driver/audio/Emu68PWM.lha).
- Record the mix into a WAV file, buffered against slow disks.
- Long DJ mixes play straight from disk: MP3 and AAC files larger than
a size you choose are not loaded into memory.
- File browser (a page of the MUI window, or part of the own screen) with
Find as you type, file sizes and a BPM column: tempos found are
remembered; MP3s also show their ID3 BPM tag. Workbench icons dropped
on a deck in the MUI window load there.
- Titles from MP3 ID3 tags and .m4a iTunes tags ("Artist - Title").
- Two GUIs: a resizable MUI window, or StormDJ's own 8-color PAL/NTSC
screen with plain gadgets (no MUI needed), optionally in overscan,
with color presets including Dark and Night (red or green) for the
stage.
- Shell mode for playing without a GUI.
- One program for the 68040, 68060, 68080 and PiStorm/Emu68; needs
neither 68040.library nor 68060.library.
- Languages: English built in; Czech, Danish, Dutch, Finnish, French,
German, Hungarian, Italian, Norwegian, Polish, Portuguese, Slovak,
Spanish, Swedish and Turkish included; more as plain text files (a
template comes with it).
- A full AmigaGuide manual (HELP key, at the chapter under the pointer);
the own screen shows it with a built-in viewer.
Requirements
------------
- A 68040, 68060 or 68080 with FPU, or a PiStorm with Emu68.
- AmigaOS 3.1 or newer (the own screen: 3.0 or newer).
- MUI 3.8 or newer, or Zune68, for the MUI window.
- AHI for sound cards; Paula also works directly.
- A few MB of free memory. MP3 and AAC files up to 16MB (adjustable)
are loaded into it, larger ones are read from disk as they play.
Installation
------------
Copy the StormDJ drawer wherever you like and double-click StormDJ. See
StormDJ.guide.
The drawer also holds StormDJ.adf, a bootable floppy image that starts
StormDJ alone, on its own screen with Paula sound, from Kickstart 3.0 or
newer. Its Install-Extras script adds your CPU library, AHI with your
drivers and a mouse driver from your own system. It carries TinySetPatch
(BSD 2-Clause license, Copyright (c) 2025, TinySetPatch Contributors; see
the guide).
