you could check the chapter `units of amplitude' [1] in
`the theory and technique of electronic music' by miller puckette.

but to the current system: what does it mean, if you increase the volume
from 20% to 40% to 60%? i must admit, i have no idea. of course, i can
check the phonon sources, but the value itself doesn't tell me
_anything_ about the actual amplitudes. the db scale is well defined and
 reducing the volume by 10dB in one program sounds the same as in
another program or on the amplifier of your speakers.

but may i just suggest, you try my patch and test the scaling yourself?

best, tim
