The Harvestman English Tear model HM2401

A collection of analog processing circuits to adapt your modular's voltages to vintage Hz/Volt instruments such as the Korg MS-20. Two attenuating/offsetting voltage processors condition the voltages before they go to log/expo amplifiers, freely converting between the Hz/Volt and Volt/Octave tuning standards. A 2-channel trigger converter facility is also available. All circuits in this module are completely patchable free from the preset normalling.

• 2x Voltage processors (attenuate, offset, mixer on channel A)
• Log and Expo amplifiers (converting expo control voltage to linear and vice versa)
• Trigger converter (changes v-trig to S-trig and vice versa)
• 10-turn trimmers on the back for fine calibration of tuning circuits
