The SIM-SQUEEZE is a synthesiser (no samples) which aims to simulate a range of bellows-driven free reed instruments. The Big Daddy of these is of course the accordion but more simple instruments can be simulated by using fewer registers etc.
The zip includes 3 plugins; 32 and 64 bit and a 32 bit one for XP users. You also get a User guide and Background info. If you get a copy of FlowStone you can open the schematic (.fsm) file and see how it works and use whatever you want for your own projects.
Now give me a big Squeeze!
