almost

would be my go to synth without a doubt, but it's visually too cluttered and tight. would be a different story w a mouse on a computer. that aside it sounds incredible.

Love this Karplus app.

Does more than just string sounds.
Great presets, and lots of tools for making your own patches.
Shines in AUV, as well as standalone.
Glad I got this one :-)

Incredible Sounds from a Small App

Most apps that provide these types of sounds use samples and tend to be very large (hundreds of MB). This app models the instruments providing much more flexibility and a very small size. I still have to try it with an MPE keyboard.

I got on sound

I downloaded the app and got no sound. I trying different settings but nothing came out. Looked the the user manual and got nothing.
