PolyHarp is a virtual musical instrument and a thought experiment. It's a testbed for harmonic theory as well as a great multi touch simulator of the good old "idiot zither" you have in the attic.

PolyHarp is a virtual musical instrument and a thought experiment.

It takes the basic idea of a chorded zither and extends it to large numbers of chord choices, made out of any kinds of intervals, multi-string courses, fretting,  and massive polyphony. It's a testbed for harmonic theory as well as a great multi touch simulation of the good old "idiot zither" you have in the attic. PolyHarp can translate many of these innovations to MIDI and is a powerful MIDI controller.

PolyHarp comes with a large number of presets, exploring many variants on stringed instruments, but its real power is its ability to build strange new chords, layouts, and controls into otherwise impossible instruments.

PolyHarp supports Audiobus 3, including saving setups, and IAA.

Version 1.0.17 release notes

Fixed some things that mostly annoyed me, having to do with using MIDI CC01 as a modulator destination, which was actually sending CC00.

Droneo is a synthesizer which drones with various timbres and precise intonations that blur the distinction between tones, timbres and chords. Its drone is great for meditation, centering, and calming,  walking and biking, but also can be set up for discordant noise and insect-like buzzing and chirping.
