Proton is Audio Damage's take on the classic Karplus-Strong tuned delay line
physical modelling synthesis. Take a capable "vintage digital" style delay line with
1V/Oct clocking, and add an enveloped noise burst, and you have a plucked string
physical model. We wrap this up in some of our standard Audio Damage aural
hijinks, and Proton is the result.
Starting with the delay line, which is "tuned" via the coarse and fine tune knobs, we
then add a quality low pass filter (modelled on the MS20's LPF) and damping
circuits. We hit this with a noise burst from an analog random number generator
that passes through two more filters and an envelope with decay to produce the
plucked sound. A "CHOKE" input empties the delay line, for extra dynamic control.
Since Karplus-Strong synthesis lacks bottom in general, we have a "SUB" control
that adds a sine at the fundamental frequency to produce gut-churning low end in
the bass register. The result is a physical model synth that is capable of both
delicate harp-like plucks and monster face-melting basslines.
