MA35 VCF/A

Internally-coupled VCF and VCA based on the Korg MS-10. The VCF uses the Korg-35 filter architecture with discrete transistors (LP/HP switchable via toggle or CV); the VCA uses the MS-10 single-transistor design for characteristic color. Includes a two-channel audio input mixer.338

Capabilities 2

Vcfvcf: Korg-35 filter architecture using discrete transistors, switchable between Lowpass and Highpass via toggle switch or mode CV jack.338
Voltage-Controlled Amplifiervca: MS-10 single-transistor VCA design, internally coupled to the VCF, adding distinct color to the sound.338

Name	Signal	Voltage	Description
Inputs (1)
mode	mixed	—	CV input that switches the VCF between Lowpass and Highpass modes.338

Parameters 2

Name	Type	Range	Behavior
Input Gain	knob	—	Controls input level for the two-channel audio mixer. Modular-level signals begin to overdrive the input past approximately 12 o'clock; below that gives a smooth, liquid sound; above gives fuzzy overdrive character.338
Mode Switch	switch	—	Toggles the VCF between Lowpass and Highpass modes. Can also be switched via the mode CV jack.338
