crazy modular drummers

[Haible_Juergen#Tel2743]

Hi!

This might not be new to You, but I had a lot of fun with it.
The idea is controlling a nearly self-oscillating filter by both a
sequencer and a sample&hold, clocked from the same
LFO. In details:

I used my SSM2040 filter module to produce percussion
sounds, like it was described many times before: The gate
output of the sequencer is fed into the filter's signal input
to make the filter ring and exponentially decay. At the same
time the sequencer's CV out controls the filter cutoff frequency.
All in all You get the impression of tuned percussion, like a
band of african drummers who use tuned/tunable drums
(is that "talking drum" or something similar?).
Now I am adding the S&H voltage, giving the whole thing a slightly
random structure: no stroke is exactly the same as in the
previous bar. Increasing the S&H amount drives Your
"virtual negroes" crazy - it's like they are falling in trance and
create unpredictable pitches - You can blend this up to full
"classic" S&H effects, but IMO it's the slow transition from
the tribal drums to the insane s&h effect that makes the whole
thing interesting.
