Moebius Lab is a multimorphic sound processor which contains a synth, a varispeed stereo sample player, 9 time domain effects, 6 spectral effects, 7 slots for external audio application, and nearly 200 LFOs that can modulate each parameter. You can move the effects along two chains, and get endless combinations of incredible sounds. ALL the App parameters can be modulated with dedicates LFO (one independent LFO for each parameter!). To get you started, you have more than 200 ready-mades presets. Each effect has an in-line help with an explanation of the parameters. The screen is divided into 3 horizontal areas: the top one contains the sound source (Sample player/External Input/Internal Synth), the middle one contains the Time Domain Effects Chain with four slots for external apps, the bottom one contains the Spectral Effects Chain. The two effect chains are connected in a sort of Moebius Ring: you can route the signal from the Time Domain Chain to the Spectral Chain and vice versa. You can even add up to 7 IAA effects and/or instruments, the number of possibilities is huge! *** LIST OF EFFECTS (NODES) *** - EXCITER The Exciter Node distorts the signal below (Saturation) or above (Excitation) a given frequency. - RINGER A ring modulator with distortion and feedback. - KLAMPER Clamps the signal with some special features. - SWARMER A “superchorus”, excellent to create super fat synth sounds (and more). It is composed by a chain of modulated delay lines. - FILTER The Filter node has two configurations: Dub: dual low-pass high-pass state variable filter with resonance and overlap factor. Morph: a triple low-pass/band-pass/high-pass state variable filter with resonance and continuous morphing between the filter types. - SPLITDEL A dual band delay with feedback. - REDUKTOR This node can be used to decimate and do other “bad things” to your signal. - SHIFTER A dual band frequency shifter. - REVERSO Plays the signal in reverse at regular rate. - BRICKWALL A spectral brickwall filter. - GRIP This node samples and holds spectral components of the incoming signal, based on their amplitude. - BLUR A (noisy) “spectral reverb”. The duration of the spectral components is prolonged (blurred). - DEGRADER A spectral decimator. - FLUTTER Flutter is a sort of animated brickwall. Two spectral sinusoidal LFOs define the frequency boundaries. The spectral components which are inside or outside (depending on the Spectral Balance) these boundaries are suppressed. - PLATEVERB As the name suggests this is a classic Plate Reverb. - DYNAMICS PROCESSOR You can change the output sound using a compressor and expander effect. This is used to either reduce or expand the dynamic range of an audio signal. THE SYNTH The internal synth contains two band limited oscillators, a complex oscillator, a ladder filter, an envelope generator and a sub-bass oscillator. Other Features: - Audiobus and Inter-App Audio support (sender and FX) - Built-In​ Stereo Sampler with varispeed - Control Manager LFO for Parameters - Midibus, Virtual Midi and Network: 14 bit NRPN controllers - File Manager, sharing common audio files via iTunes, Dropbox and AudioCopy - Snapshots Presets Morphing Pad

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 ;-)
