This Teisco is the bigger brother of the Kawai S100. It seems to be designed for the hard of hearing: everything you do will light up a led somewhere on the panel. The fact that it looks like a veritable Christmas Tree in the dark, actually covers a very nice interior! The moog-type filter is constructed so it does not lose low frequency when the resonance is turned up. The filter is perhaps not so strong and natural as a moog filter and working with this machine I often feel just like that: working with a machine, because that is what it sounds like to me. Of course for very many applications this is not a bad thing! And I must say I have enjoyed (and am still) using this synth.
Comments About the Sounds:
The filter bank offers great opportunities. The low pass VCF of this synth is really nice, retaining low when resonance is turned up.
