Sound sculpting with Black LP VCF, HP VCF and Filter Coupler
The Black Filter Coupler from Erica Synths' high quality Black series is a satellite module for the Black High Pass VCF and the Black Low Pass VCF. The module is not a standalone filter but an expander for the two mentioned filter modules. It addsBandPass and Band Reject modes to the two filters allowing adjustment and CV modulation of center frequency and bandwidth while still allowing both VCFs to operate independently. The necessary connections between the three modules are done with ribbon cables on the back.
