Featured in the US Appstore! Here's what the reviews say: "Perfect for on the move acid sessions, the Trouble Maker app faithfully recreates the sound of the original TB-303" - DJ Mag "Troublemaker is absolutely no trouble at all to heartily recommend" - SoundOnSound "If you want to make the bassline from Josh Wink’s ‘Higher State of Consciousness’ on the bus, this is the app for the job" - Factmag.com "Top-notch stuff from a developer that just keeps getting better" - Musicappblog.com "This app has been consuming all of my time this week! Love it!" - Discchord.com 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 square wave with its oddball shape and shifting pulse width. 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: - 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 ruismaker.com - 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 ;-)}

An amazing emulation of the classic 303. The standalone editor for creating bass lines is great and the best implementation I've seen so far, even though it's quite a hassle finding the right notes. What's truly missing is a midi learn function to assign knobs freely to the parameters. In my opinion a 303 emulation needs nothing more than being able to tweak the sound by physical knobs. Somehow the developers either forgot about that or the function is somewhere hidden where no one finds it...

This app is great.. especially in duo instances. Brams work is the best ;) Awesome Job on this one man.

Pero... por qué no 5 estrellas? Es un poco desconcertante tener la Freq y la Reso en el orden inverso al que todos estamos acostumbrados. A la larga, me resulta indiferente, porque me gusta el Controller, para agarrar con los dedos los botones físicos y lo configuro a la usanza. Maravillosos add ons en formas de onda y fx que convierten esta App en una auténtica bestia.

The app is broken for me. I can only see the sequencer - the whole top section is missing. No sound is coming out. Also it doesn’t show up as plugin in AUM. It’s practically unusable and this is unacceptable for a 10 euros app. Please fix it or I’m gonna ask for a refund.

Wie kann man das, was aus dieser App raus kommt, mit dem Sound einer 303 vergleichen??? Wer zu Glücklichen gehört, die den Rebirth RB-338 kennen, wissen das es geht. Wie auch immer, dachte dann nehm ich die App halt als Sequenzer, aber Midi-out funzt auch net. Alles in allem, eine doppelte Enttäuschung.

I have tried many TB-303 copycats, both hardware and software, and nothing comes as close as this. Burbles and warbles like the real thing. Dynamic sound, lots of control, and the sequencer is dead easy to use as well if you want to work in- box.

I’m a big fan of everything I’ve tried from Bram Bos. This is just a great Acid bass synth with a fun sequencer that doesn’t settle for just being a straight TB-303 knockoff. More waveforms and onboard effects make it really versatile. It’s easy to get great sounds from it. Running it as an AU plugin makes it easy to automate knob tweaking using the Rozeta LFO plugin. I’d love the ability to save/load presets from files/iCloud while running as a plugin.
