Beast's Chalkboard

A dual channel stepped voltage source and adder in 6 HP: each section adds -2 to +2 volts in 1 V steps (five octaves) to the voltage at its input, at two buffered outputs, with a buffered Thru of the input. Mainly a dual octave switcher for VCOs; also sequence transposition, FM ratios, buffered CV distribution and VCO calibration.

Key features

• Two sections, each a five-position switch from -2 to +2 V (1 V steps)
• Two buffered outputs and a buffered Thru per section
• The top input normalled to the bottom one
• Chaining the top output into the bottom input extends the range to -4 to +4 V (nine octaves)
• With the switches at 0, a 1 to 6 or dual 1 to 3 buffered mult
