Some of the new features:

• nearly alias-free analog oscillators
• pulse width control on the square oscillator
• all the filters have been re-written and have been fattened up quite a bit
• several wave-shapers
• ADSR envelope editor
• note on/off for sustained notes
• multi-page/octave sequencer
• you can now draw notes/modulation in the sequencer
• recording into the sequencer via the midi keys
• sample recording/re-sampling
• full featured sampler
• and manymore…

Jasuto is still under pretty heavy development, so it will be improving/changing quite often. Feedback will certainly have an influence over the development direction.

Jasuto is the first truly modular synthesizer for the iPhone and is basically the 2nd coming of my previous modular synth experiment known asMode

There are several main design goals that I wanted to achieve with this.

The first goal was to make synth building fun and easy all while adding some unpredictability to the process. I’ve come up with some amazing sounds almost by accident in a lot cases that I would have never even thought of doing in a conventional synth.

The 2nd was to blur the line between patch and synth, so creating a synth should be no different (or any more difficult) than creating a patch.

The 3rd was to unify control and audio rate signals allowing everything to be a modulation or be modulated.

And finally I wanted to make sure that it was simple and efficient to add motion to a sound. So every node on the screen can record its own motion.  E.g. if you wanted to create a simple LFO for a chorus effect just attach a constant to the delays time port, click the record button and wiggle away.  After you are done recording hit stop and it will auto-magically blend the loop points for you. All motion including the step sequencer are syncable via triggers, more on this in the “Basics” section.

And that’s really what this is all about, it lets you explore soundscapes and make synths without even knowing it.
