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.

Great app but it needs CC mapping

Really nice app but I am surprised you don’t have any provision to map CC controls with it. I play a windsynth controller and this is a must need for the synths I use. I am aware I can probably map parameters in AUM and use Loopback to get the audio into Logic but that introduces more latency. Hope you can add CC mapping to this app and Copperhead (also a great synth)
