Create Unique Sounds

Sample editor in Jasuto on iPad

Jasuto allows you to visually construct your own synths/effects and use them to make sequences all on your device!

Includes a fully-featured sampler (now in stereo) to record/resample/edit as well as 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.

For a Quick Start Guide, further details on creating scenes and all of the astounding capabilities of Jasuto, check out the revised Manual (for version 1.6).

Connect And Be Inspired

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 demo scenes and samples. Each of the modules, scenes and samples have been hand-optimized for your device's CPU, allowing you to create extremely complex and unique scenes.

Group and connect nodes together to compose sequnces or samples. Then use solo and unsolo to create original tracks.

Connect Jasuto with Midi devices to use the new Midi-In & Out node with tempo sync.

Hi-Fi Audio Listening Quality

Jasuto with Hi-Fi enabled

High Fidelity is a new feature that was added in Jasuto 1.5.

With Hi-Fi activated you can listen to your scenes, patches and music creations in studio quality.

All samples, scenes and nodes have been updated to studio quality as well.

You can easily switch between Lo-Fi and Hi-Fi without leaving the app.

Latency is an Android only Menu item that controls the DSP buffer size. Smaller latencies decrease the time it takes hear the sound after interacting with the screen, but increases the CPU usage.

Frequently Asked Questions

Since Jasuto v1.5 update, we have removed the download files from the site.

With all the buggy issues in the past versions using the FTP, we have done away with that starting with Jasuto v1.5. You can now share your samples to SoundCloud or sync any of your samples/scenes with Dropbox. Please see the manual for setting those up in the app.
No need to fret, any scenes/patches/samples you created in previous versions of Jasuto Pro and added to the Scenes/Samples folders (NOT in the Community section) will still be there when you upgrade to version 1.6. If you have Jasuto classic (v1.3.0) and want to save those scenes before switching over to the new Jasuto, you will need to save them to your computer first and then after setting up Dropbox, sync them.
