Here are some things Ive had lying around in various states of finishment.
Polypad a easy to use to use polysynth. The polyphony is a basic first in last out note stealing. It also has a basic FX section to spice up the sound. I made it for making big pad sounds.
Monochord 2 this has been languishing on my hard drive unfinished for about 18 months. Can make some crazy sounds. Similar to original Moncord with an extra Oscilator and some other wacky stuff.
