The Noisemusick app is a collection of three controllable synthesizers that generate interesting chaotic sounds. Have fun creating sonic bedlam, exploring weird soundscapes, or use it to great effect in your live performances and recordings. It's squonky electric fun for the whole family! With Noisemusick you can: * Choose a sound to match your mood: blue, green, or pink * Practice and probe to find interesting interactions of sound * Discover weird oscillations * Use it as a raw input to other filters and effects * Run on an iphone or iPad; it's a Universal app To start making sounds with the Noisemusick app, your body has to complete the circuit between the touch pads. Pressing the pads in different combinations will generate different frequencies and modulations. By lifting a finger or sliding the hold switch you can create rhythmic patterns of noise. Move your fingers to change the resistance between your finger and the pads, which changes the frequency and beating of the tone. On each board the knobs change the quality of the tone in different ways. This is a Universal app from the Fluxama collective in Providence RI.

ButterSynth is a hybrid 6-oscillator wavetable/FM/sample-based AUV3 and standalone synthesizer with a vast sonic range, from gentle pads to screaming leads and basslines. Mix any combination of wavetable, FM, sample and other synthesis engines for one truly massive sound. For the more advanced users, you'll love using ButterSynth's thoughtfully designed interface, incredibly powerful modulation matrix, fully-featured internal FX rack, factory waveform and sample libraries, and almost limitless scope for fun, experimentation and sound design. For less experienced synth programmers, ButterSynth includes a library of hundreds of ready-to-use presets, sparking your creativity to start making music right away. Headline features include - Mix and match any combination of 6 synthesis engines to either emulate your favourite synths of yester-year or build a synth ready for the future. - Dual-wavetable engines also feature 9 phase modes, wave folding, and deep unison controls modelled on vintage hardware synths. - Built-in wavetable editor gives you the ability to tweak, morph, and hand-draw your own custom wavetables, with each wavetable supporting up to 256 frames. - FM engine offers 4 operators with a selection of 12 modulation paths. Each operator can be loaded with any waveform from the factory or user library, and can also self-modulate via the feedback dial. - Sample and Granulator engines both let you load samples (either imported or from the factory library) and control precisely how they are chopped, triggered and layered. Both also feature the same powerful unison modes available in the WT engine. - Highly configurable 32-slot modulation matrix featuring precise mix/max ranges, self-modulation (via the amount target), plus configurable response curves and layer modes. Simply long-tap any parameter to set it as a Mod destination! - Full suite of versatile control sources which includes: 4x MSEG-style looping curve envelopes, 4x LFOs, 4x step sequencers, X/Y pad with motion recording, 8x Macro dials and a powerful arpeggiator inspired by Kirnu Interactive’s Cream. - The EFX rack lets you build your own insert effects chain using any combination of the 16 built-in FX modules. Modules available at launch include delay, reverb, distortion, chorus, OTT compression etc. Note - FX parameters can also be targeted by the mod matrix, unlocking the possibility to program ‘per voice’ modulated effects. - All presets, wavetables, samples and other settings are stored in the Files app, making bulk import/export, backup and community sharing quick and easy. - All of this is housed in an irresistibly designed 4-tab UI that makes synth programming quick and fun.

Verdict
The clearest difference is price: Noisemusick at $0.99 against ButterSynth's $19.99. Noisemusick also leads on update cadence (every 2 weeks vs every 2 months) and review sentiment (79% vs 59%). ButterSynth's advantage is rating (4.0 vs 3.6). On ratings volume, ads, in-app purchases and device support there is nothing between them.
