Here’s an experimental patch to try out the new Dual Plague Bearer module.\u00a0 I patched the triangle waves from two MOTM-300 VCOs into each of the two P.B. inputs.\u00a0 The WoggleBug Smooth output provides FM for the first VCO, and the Stepped output for the second VCO.\u00a0 The WoggleBug clock output drives the MOTM-730 divider that in turn gates four MOTM-800 Envelope Generators.\u00a0 These modulate the Plague Bearer Hi and Lo CV inputs.\u00a0 (The Mattson Distributor was perfect to use as attenuators on the four CV inputs.)\u00a0 I derived two common gates using the CGS digital logic XOR function and used those to trigger two Oakley ADSR\/VCAs for overall amplitude control.<\/p>\n

The key to this patch is running the VCO’s initially at sub-audio rates.\u00a0 At sub audio, the signal excites the P.B. to produce chirpy\u00a0 sound.<\/p>\n\n\n
