The star of today's PotD is Doepfer's A-143-1 Complex Envelope Generator. Supporting roles played by a Sequentix P3, Kenton Pro 2000, 4 VCOs and Cwejman's VCA-4MX.
I've used the A-143-1 to create a ripple effect. Each 'note on' triggers a succession of four envelopes which are patched to the four inputs of the VCA-4MX. By changing the Threshold level, the timing of the ripple is affected. This effect can be further pronounced by changing the A/D times of the envelopes.
The P3 generates a four note sequence which is transposed using an accumulator in bi-polar mode. The Kenton is set to polyphonic mode, so that each new note is sent to the next VCO in the chain, adding a slight 'analogue shift register' feel to the patch.
