A Microtonal Guitarist's synth, designed for extreme playability on the iPhone and iPad. It is the successor to Geo Synthesizer and Mugician. It does send a specialized MIDI output (requires a multi-timbral synth that can handle independent channels is all but necessary, such as SampleWiz or ThumbJam in OMNI mode, or Arctic Synth). The internal synth is driven by the actual MIDI output, because external MIDI synths are the main point of this project rather than the internal audio engine. It has a basic looper/delay combination, and the loop can be copied out as a sample to the general pasteboard for apps such as GarageBand.

It is very expressive in terms of per-finger filtering (channel pressure tracks finger-area, CC11 tracks vertical position).

The MIDI code used in this project (formerly called AlephOne) is in this open source project:

This project traces its origins to to Mugician, and Geo Synthesizer (which was released on Wizdom Music with Dream Theater's Jordan Rudess and his developer Kevin Chartier). See the numerous youtube videos and tutorials on how to play those instruments, as those lessons apply.

Very nice advancements! (5 stars)
This app has taken some nice steps forward beyond Geo synth and Mugician. The first is the finger-area sensing which grants a high degree of expressivity in playing. The second is the assignable fret feature; no longer are you restricted to a set of scales, you can now create any scale you would like (including a variety of microtonal options). I have tested this app with Thumbjam and controlling soft synths on my PC and everything has worke

Get this app NOW! (5 stars)
This app is a gift at this price. It is the perfect companion to ThumbJam or any midi controlled program. Users will find similarities to Geo Synth with a few new features and a few left off. The layout uses the entire screen and is optimal for guitarists. To get the most out of your experience try using it with midi. It is well worth your time.

Great (5 stars)
It is wonderfully expressive! It works with Sunrizer! The layouts are easy to change and it just feels good overall. Great price too!
