Further information from nonlinearcircuits:

This module is loosely based on the Karplus Strong algorithm. You may

get it to make some plucked string sounds or you might just get lost in

a rubbery glitch mess. Most likely, Messrs. Karplus and Strong would

drag me out into the carpark for a kicking if they heard this module……or

even saw the name.

This is not a press-a-button-and-sound-cool module, it takes tweaking.

To get started, it needs a trigger or gate on the EG Trig input.

Make sure Noise Level is turned up, Noise Colour goes from white to pink

noise. This pot is disabled if an external noise/sound seed is used.

The Attack and Decay pots need to be set, Attack can stay at 0 for more

of an impact, Decay should be above zero to get some sound into the loop.

In a proper K-S system, the envelope is very short so just a portion of

the sound wave is obtained. In this module the envelope can be held open

for a few seconds. The EG can be easily modded to keep the envelope very

short but it is more fun to have the option for longer envelopes.

Next turn up the Feedback and Rate pots, probably somewhere around the

area shown in the pic above. After this, adjust Cutoff until you can

hear something. Once you have a sound you can start sculpting it and

adding CV to get things moving around.

Both the Q and Feedback pots will make the module self-oscillate when

turned up high. Getting the sounds you want often comes down to a

delicate balancing act between these two pots.

The VCO / BBD clock should range from approx. 100Hz to 300kHz. This is

above and below the normal operating range of the BBD chips. It is fun

to use the lower frequencies to get some lovely DelayNoMore type effects,

tho the Cutoff pot will have to be tweaked to reduce the clock noise.

The VCO is approx. 1V/oct but has no temperature compensation.

The module can be fitted with a V3207 1024 stage BBD OR a V3205 4096

stage BBD. Only install one or the other, not both. Initially I liked

both versions, but feel the V3205 sounds better with slow clocking

glitchy stuff, so prob that will be the one I keep in the rack.
