Read full description

It was never so easy to create beautiful sounds and driving loops. The unique dynamic wavetable synthesis allows you to explore an unprecedented wide range of sonic territory. From acid loops, crystal clear percussions, realistic human choirs to complex musical soundscapes nothing seems impossible with only a handful parameters to tweak. The new spectral noise generator adds a new dimension to the already huge sound universe of Addictive Synth. This generator is the first of its kind and allows for extraordinarily detailed control over the dynamic spectrum of the noisy part of sounds. Despite its complexity it's pretty easy to use and integrates naturally into the sound design philosophy of Addictive Synth. Together with the intelligent randomizer for both sounds and arpeggios you will loose any sense of time and space while exploring unknown sonic territories. Right from the beginning you'll understand why it's named Addictive. ***Best iPad Apps of the Week*** AppAdvice.com "Addictive Synth fixes your craving for a massively customizable synthesizer experience on the iPad." - AppAdvice.com "App Of The Week" at iDesignSound.com Features: Dynamic wavetable synthesizer • Six dynamic wavetable oscillators per voice, up to 48 total. • Continuous morphing between two oscillator sets. • Realtime editing of up to 128 partials (overtones). • Realtime editing of filter structure to create arbitrary body resonances. • Extensive modulation possibilities using up to 4 LFOs and 4 Envelopes. • Control matrix allows real time control of five parameters using the X/Y touch pad, the modulation wheel and the tilt sensors of the iPad.  • Monophonic or polyphonic with 8 voices. • 128 factory presets, unlimited user presets can be shared.  • Up to three effects concurrently usable selected from: equalizer, phaser, flanger, chorus and stereo/cross delay.

What the reviews say: "A must-have drum synth for electronic music lovers on iOS" - Keyboard Mag "All of this comes together in a vision that’s really playable [...] this is another excellent choice for the iPad." - CreateDigitalMusic "Small, compact and easy to use, Ruismaker is both inexpensive and a perfectly credible choice if you are after solid drum synth sounds." - MusicAppBlog -- Ruismaker is a unique drumsynth plugin (i.e. it does not use samples), which is coupled with a creative Euclidean sequencer when run in standalone mode. The plugin is fully AUv3 (Audio Unit) compatible: - Seamless integration with Garageband and other AU hosts - Audio Unit Instrument: making music on iOS doesn't get more convenient - Supports Multi-Output AUv3 in AUM and ApeMatrix! - Each sound is modeled using authentic analog and FM algorithms; - Comes with dozens of unique customizable models - Does not use any samples; all sounds are synthesized in realtime, on the fly - Emulates analog components, introducing subtle, natural fluctuations in the sound - Light on the CPU, so you can run lots of Ruismakers simultaneously - Fully automatable parameters (requires host support) and MIDI CC controllable - Has its own preset manager The standalone sequencer is refreshingly different: - Program patterns using Euclidean algorithms - Powerful random feature and mutation probability settings per channel - Syncs with Ableton Link or MIDI Clock - Exports WAV and MIDI - Compatible with Audiobus 3 (including MIDI IN/OUT mode) - CoreMIDI In and Out - AU MIDI output for the on-screen pads User manual available on Ruismaker.com

Verdict

The call

The clearest difference is rating: Ruismaker at 4.8 against Addictive Synth's 4.5. Ruismaker also leads on update cadence (every 5 weeks vs every 4 months) and price ($4.99 vs $6.99). Addictive Synth's advantage is iOS requirement (6.0 vs 11.0). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.
