[lively-kernel] More Sounds!

[Alan Kay]

Hi Dan

Unusual amplitudes. Notes seem to get louder going lower in pitch -- or by voice -- this could possibly be helped a bit by the volume control on each voice that we used to have in the Squeak player.

Also, some "interesting" background artifacts in the sound -- aliasing from no low pass filter?


Cheers,

Alan
