MOTM

Because of past talk about the Moog String filter and related stuff and Juergen Haible building a string filter, I figured I'd post an ad to an unknown string filter that I cut out of an ancient Contemporary Keyboard issue decades ago. According to somebody on I think the Virus list from a few years ago, only one was ever made and he ended up with it. Unfortunately he wasn't using it for its intended purposes but as a distortion unit he said. What a wasteful use of an interesting piece of gear. So here is probably the only time you'll ever see a picture of one in your life:

Each filter has a 3 position switch under it, not sure what they do. I can only make out two of the knob labels, which looks like MODE on the 2nd knob, and RESONANCE SHIFT on the 4th.

Hi Ken and list,

the picture is too small to really tell anything, but my guess is that
the Faders (obviously) give individual attenuation for each band, and the
3-position switches either

(a) make a hard panning of each channel to left / center / right

or

(b) switch each band on (in phase)/ off / on (phase inversion).

That's the two things I'd consider interesting, at least.

Formula Sound is an existing company in the UK that makes mostly
high-end DJ mixers. Might be the same company:

The font used for the filter company name looks very similar to this
company. Might be worth an e-mail.
