Yamaha GX1 Bandpass Filter/Resonator
By Old Crow Modular
This board is for the Yamaha GX1 bandpass filter/resonator as used in the GX1 voice. Originally this filter had a fixed Q of 5 and was used to select harmonics from the ramp waveform that could be mixed into the patch. The NE11000TH filter preserves the exact topology of the 1974 Yamaha original but brings the filter to the eurorack modular user requiring only 4HP of panel space. This includes a variable Q control, 1V/Octave CV response, an FM input with panel control. Customers who purchase bare boards will receive a pdf document via email that includes the bill of materials and parts placement diagrams as well as operation notes. Builder may use either a 2x5 power header or a 2x8 power header.
The optional front panel is designed for 9mm pot bushings and Cui MJ-3536 right-angle 3.5mm jacks.
