Thru-Zero Quadrature VCO/VCF (QVCO)

Thru-Zero Quadrature VCO/VCF (QVCO)

2007-03-19 by Wim

Hello,

Is there any news on the development of the Thru-Zero Quadrature VCO 
already? It still looks like an interesting addition, certainly with 
the option to link it to the A-126.

Kind regards
Bill

Thank you Dieter, the A-100 rules!

We are still working on the Thru-Zero Quadrature VCO but it will be not
ready for the Frankfurt Musikmesse. In Frankfurt we will only show the
Quadrature LFO/VCO without the Thru-Zero option. But the suggested quad VCA
(four VCAs) module will be ready and can be connected interally with a
ribbon cable to the Quadrature LFO/VCO.

We will also show the quad VCF/VCA/Panning module A-135-2, the crossfader
module A-138d, the mix expander A-138x, the tapped BBD module A-188-2, the
scope module A-192-2, the SEM filter A-106-5, the A-100 CV/Gate keyboard,
the "A-100 beauty cases", some new DIY devices for self-building of A-100
frames (e.g. several DIY power supplies with different power, special
mounting rails with threads) and some new OEM modules (e.g. an USB board
with 64 inputs for switches or potentiometers, and a low-cost "wheel
electronic" especially for modulation wheels, joysticks or breath
controllers).

I hope we will be able to show also the dynamic VCO A-111-1 and the
universal AD/DA module. These modules are still at the customs (back from
NAMM) but we hope that we can release them in time. The dual SCF and the PTV
module will be not ready for Frankfurt. The designs are a bit more complex
than we expected.

Best wishes

the last thing I want to do is to complacate things even more, but as 
the scf is still being developed: maybe the owners of the a-188-2 
would be interested in a steeper slope than 36 db (i would :-)

greetings, Anton
