Rob Hordijk Phaser Filter

Contact Rob directly for details about his designs: rhordijk@xs4all.nl.

Rob also has his own subforum at the Electro-Music forum site: http://electro-music.com/forum/index.php?f=185

Most of Rob's module designs use SSM quad VCA chips, possibly the Analog Devices SSM2164 (?)

HRM VCO The HRM VCO module can morph from waveform to another because it builds up the harmonic content from a sine and cosine waveform. You can morph with CV from sine to triangle.

Dual Phaser  Price: 385 Euro. The phaser module can do waveshaping and ring-modulation, and can also act as a VCF. It can perform spread-modulation. It is an OTA phaser (8 pole and 2 in a module.) When nothing patched into phaser 2 the second phaser goes parallel to phaser 1 with the input inverted. With the same settings, you get almost full cancellation from the output.

Active Matrix Price: alittle under 500 Euro. The Active Matrix module is buffered and works similar to the EMS Synthi. It comes with mono plugs and some have built-in resistors for -6db or -12db signal reduction. Every point is an insert, and with an insert cable, you can patch whatever you like into that point.
