[ACCOLADES] - Featured in Apple's staff favorites! - Reviewed in Computer Music magazine and received a 9/10! [DESCRIPTION] Jasuto is the worlds first (and most powerful) modular synthesizer for the iDevices. Jasuto allows you to visually construct your own synths/effects, and use them to make sequences all on your device! With the addition of a fully-featured sampler you can now record/resample/edit, and even create entirely new samples by drawing right in the app. Jasuto uses the relative position of nodes and their connections to control the sound. So the scene not only represents the synthesis structure, but also a custom multi-touch control surface. Motion can be recorded per node giving you rich, flexible automation. Connections can be created automatically by simply dragging nodes around, or manually. Each wire can be double-tapped to allow even more control of each connection. Jasuto comes installed with 75+ modules as well as 200+ pre-loaded scenes and samples. Each of the modules have been hand-optimized for your device's CPU, allowing you to create extremely complex scenes. [NOTABLE FEATURES] - Anti-aliased oscillators with hard-sync, FM, PWM, PM - Analog style filters (ap, lp, hp, bp, ladder emulation) - Signal control (compressor, limiter, gate, follower) - Zoomable sampler editor with several loop modes (normal, 1 shot, ping, granular) - ADSR envelope editor - Multipage/octave sequencer - Tape style analog delay - Reverb, phaser, several waveshapers - Resample/record the current playback - Audio copy via the pasteboard - Incoming OSC and MIDI for notes and CC's - Audiobus support (input, effect & output source) - Completely compatible with iOS7 - Updated UI graphics - Universal device and Retina support - A shiny new manual - Added background audio support - Low latency audio (256 samples) - Sample sharing through SoundCloud - Dropbox syncing of samples/scenes - High Fidelity (Hi-Fi) Audio [WEBSITE] http://www.jasuto.com

Please note: this is an AUv3 plugin that can be used with compatible host Apps. TimeVerb-X is a new plugin from GSi that combines GSi's “classic” Type4 spring reverb, first released in 2008, and a new algorithmic digital reverb. The “Type4” spring reverb emulation was originally inspired by an Accutronics reverb tank type 4, like those used in classic Hammond organs of the A100 series, also used in many famous electric guitar amplifiers. The digital reverb, instead, was first developed for the GSi Gemini sound module, but was also included in some Crumar hardware instruments. Both effects have been slightly expanded and further improved for the release of TimeVerb-X, as the spring reverb now features a self-oscillating feedback decay adjustment and a stereo width knob, and the digital reverb includes the early reflections section that was missing in the original project. Both reverbs put together make up a great sound when working in parallel, and create some interesting atmospheres when working in series. TimeVerb-X main features: - Spring reverb "Type 4" with feedback and stereo operation - Digital reverb with pre-delay, early reflections and room size adjustment - Built-in programmer with unlimited number of Programs (comes with 16 factory Programs) - Integrated user's manual - Comes with AUv3 extension

Verdict
The clearest difference is price: Jasuto at $4.99 against TimeVerb's $14.99. Jasuto also leads on update cadence (every 3 months vs every 17 months) and ratings volume (38 vs 4). TimeVerb's advantage is rating (5.0 vs 4.1) and review sentiment (100% vs 80%). On ads, in-app purchases, monetization model and device support there is nothing between them.
