Buzzer 2 doesn't sound much diferent than busser 1, but the interface is MUCH nicer. MUCH MUCH MUCH MUCH nicer.

Great littele analog module. I wish there were a vst version.

Excelent for Garage Band users wanting a more retro 80's(ish) sound.

No it doesn't have "presets" but the "new" button is really cool as it randomly assigns parameters greating a new "random" instrument. If you like it, tweak it & save it.

Nice module. Thanks a bunch.

Well, Buzzer has build-in presets but GarageBand 1.0 just does not show them. Update to GarageBand 1.1 to see the build-in presets.

This is a great little virtual analog synth. Very efficient, nice interface, and a friendly developer. It doesn't come with many presets, but you can easily make your own. If you have an Audio Unit-compatible sequencer, you've got no excuse to miss this gem!
