"Vendor Info:
Frequency Central proudly announce the release of the ‘System X Filter’.
It’s a clone of the Roland System 100M VCF, and uses 2 x LM13700. There’s an additional 12dB/oct output which is 180 degrees out of phase with the 24dB/oct output. Mixing the two outputs will give bandpass.
First up, classic 24dB/oct LPF. The two VCOs are my Hearn Morley HMVCO1c, there is a little -1oct subosc added as FM of the VCF towards the end of the clip:
Roland-12 1-24dB-LPF.mp3
Next, the 12dB/oct LPF output, again a touch of subosc FM towards the end:
Roland-12 1-12dB-LPF.mp3
Finally, by mixing both 12dB/oct and 24dB/oct outputs in equal amount we have the bandpass mode:
Roland-12 1-Bandpass.mp3
Module width: 10HP
Module depth: 65mm
Current draw: +10ma/-10ma"
