Modartt probably have it on their tudo list, but we need to wait, as they have a long list.

I believe soon or later a beutiful harp add-on will come.

By the way I have a suggestion for a add-on, a very simple, with not many strings:

Ok, it's kind funny... a single string instrument.  Even more weird if we think it do not have properly musical notes, but some weird noises. It's quite a chalenge to imagine how a digital instrument could emulate something like this.

Now i am asking again for a beautiful chromatic 48 strings harp add-on, with metallic strings on the last octave (from G), for Pianoteq, because there is not really beautiful harp emulated in VSTi.
after, there will be presets for some celtic ones, lyres, and so on.

Best
