This app is only available on the App Store for iOS devices.


YUMI:synth is the worlds first realistic sounding bowed string simulator for iOS. All sound generation is completely synthesized, absolutely no samples are used.

You can play two strings at once (at different locations on the scale) and bow manually or automatically. The scale system allows you to quickly define all the playable notes.

Also included are two high quality stereo effect units: ping-pong delay and reverb.

You can easily save/load presets, and backup your presets via iTunes.

To play in Manual mode, touch a string (purple or blue box) while sliding your finger on the bow (yellow box). In Auto mode, the bow slider turns into a slider controlling the volume.

The control under each string allows you to move/zoom your current view of the scale.

What's New in Version 1.1

1) Universal support for iOS 4.0 and greater devices.
2) Improved sound quality.
3) More natural default preset.
4) Removed homepage button on iPad.

Customer Reviews

Brilliant app. Nothing else like it!

At first I had trouble getting a sound out, then I realised you have the option of playing the bow at the right-hand side of the screen while holding the notes down OR set it to 'auto' in the sim tab. Now I'm hooked. A great instrument for the price of a mars bar at the petrol station, seriously- how could anyone give 1 star?!?

Improvements that would be handy would be to make it Audiobus-compatible and / or for there to be a way to record your performance and export it via clipboard.

Great app though. So glad I got it!

Have a little patience an good things will happen

Very original, simple tool, I'm actually a bit staggered at some of the sounds if been getting out of this. Have closer look at this one!
As ever audiobus, IAA, or some contact to the outside world would make this spot on. And all for the price of a packet of biscuits!

Lovely app in need of an update

Everything about this lovely app is worth encouraging the developer to issue an update - starting with Audiobus - please!
