The usual way to generate a tonal noise sound is the usage of a noise source
(e.g. A-118 or A-117, I'd prefer the A-117 for industrial sounds) and
process the noise by a band pass or low pass with high resonance. You should
use a filter with good 1V/octave tracking (e.g. the SSM or CEM based filters
of the modular system like A-105, A-106-6, A-107, A-109, A-121, A-122).  You
could also try out to overload/distort the VCF for a more dirty sound. To
obtain a percussive sound the filter output has to be processed by a
(exponential) VCA controlled by an ADSR.
