User reviews

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.

Being Honest

There’s no sound to this on this plugin

MPE and normal Midi support a bit incomplete…

I do get very nice sounds out of this synth, also the models are fine. But a synth, be it anlog or modeled or digital can only live up to its potential if I can control it with my controller. Not only the MPE implementation, also a dumb keyboard has more to deliver than an on switch.
I would expect that the damping of my model is changing when I release a key. That doesn’t happen. It is like the sustain is always on. Why limit modulation to cc1 and cc2 and remap aftertouch and cc74 to those? And they don’t seem to be per voice either. They also can only modulate a single parameter…
The articulation selection could be a menu to set multiple controller sources: cc74, aftertouch, Release velocity, and more…
If all this would be implemented I would happily give the full 5 star rating… Though it is incomplete I will give it not 3 but 4 stars for its nice sound and general idea. Look at is as an expression of trust…
And as extra wish, let it be opened in MacOS as well, that would be great…
