This patch is based on the basic Karplus-Strong example in the Doepfer A-188-1 hardware manual (https://doepfer.de/a100_man/A1881_man.pdf). I highly recommend checking out the original Doepfer hardware manuals if you are using the Softube versions.

The only changes are using the A-118 Noise source instread of the A-117 DNG, and the addition of a reverb effect.

A non-Western scale seems to be produced (a 17 note scale?), so notes on the keyboard have to be carefully chosen for something more Western.

The option of putting a VCF in the BBD feedback easily goes into self oscillation unless the noise/VCA/ADSR is replaced by say a trigger pulse instead.
