MOTM-480 Resonant Filters

MOTM 480 Resonant Filters mod panelQuantity: 1
Modifications:
Housed in a custom 3U panel that provides 2 mixed, pot-attenuated inputs for each VCF and all six outputs. Voltage control inputs are separated as well. Built with a panel designed from this Front Panel Express file.

The MOTM-480 CS-80 Resonant Filter consists of two identical state-variable Voltage Controlled Filters. Each filter features:

1V/Octave frequency control input
FM input with reversible attenuator
VC resonance input
High pass, band pass, and low pass outputs

In conjunction with Larry Hendry, I designed a 3U-wide panel with complete features for both filters, so that they can be used independently. Each filter has a two-input mixer and simultaneous high pass, band pass and low pass outputs. Each filter has its own three VC inputs. Four buffer circuits are needed for the four new outputs, and these buffers were built on a MUUB-4 board (see parts list). Visit the PROJECT PAGE.
