Introducing Troublemaker: this is not a 303

The legendary TB-303 has magical properties; it is filled to the brim with analog shimmer. Its output jack is a gateway to a parallel universe and when you twiddle the filter knobs an army of highly trained pixies chisel the square waves from freshly harvested unicorn souls. So if you want a TB-303, you should buy a TB-303. But if you're after *that sound* Troublemaker will give you everything you need in spades.

Troublemaker sports a carefully crafted diode filter emulation and among the available oscillators are the typical raspy, nasal sawtooth and rubbery squarewave with its oddball shape and shifting pulsewidth.

It also has the wow.

Troublemaker is fully Audio Unit (AUv3) compatible, so you can go wild running multiple instances in your favorite DAWs.

It also has:
- Ableton Link synchronization,
- MIDI CC controllers for all knobs (predefined),
- Core Midi, Virtual Midi, Bluetooth Midi input,
- MIDI Clock Sync, MIDI Start / Stop support
- Realtime Mutation Probability Engine
- Standalone sequencer supports 1-64 steps
- Audiobus 3 support (audio + MIDI)
- Exports MID and WAV files from the standalone sequencer
- User manual and MIDI charts on
- Comes with an extra AUv3 plugin version of a modded Troublemaker unit

And unlike the TB-303, it can actually sound like a bass guitar ;-)

What’s New

Version 1.7

Now includes a used, lightly modded, heavily battered Troublemaker unit that has seen better days. Sounds like its circuits are 30 years old and some components have been bypassed or tinkered with. But, hey, you got it for free so who cares? Look for it in your AUv3 plugin folder.

keekoon ,


Encore une magnifique application avec un séquencer malin et efficace. Remplace largement ma 303 qui a finie a la poubelle.

Ps : si nous pouvions utiliser le génial séquencer dans cubase par exemple, j ajoute une etoile

analogSystem ,

Please s'il vous plait

S'il vous plait, faites qu'il soit possible lorsqu'on l'utilise dans un daw comme beatmaker 3, d'avoir la possibilité que le séquenceur interne soit AUSSI disponible, car dans beatmaker 3 il n'est possible de l'utiliser "uniquement" avec le keyboard.

Please, make the possibility to use it with the internal sequencer in daws like beatmaker 3... not only the keyboard... please

Sinon le top du top sur ipad, le son est vraiment bon!

Émulation sympathique

Mais : pas de mémoires et le Bluetooth mode fait crasher l’application
