IC Circuits

[Gandal]

Hi Guys
Sombady can say to me what about IC circuit VCO/VCF/VCA there is inside Microbrute?
Who produced it?
Curtis or another brand?
Thanks Grazie

Nobody know what about IC there is inside Microbrute?

I don't know if any specific ICs are used in there.

But if you really want to know, you can always ask the designer Yves Usson, he certainly knows.

You can find him on http://hackabrute.yusynth.net

On that site there are no schematics yet of the microbrute, but there are for the minibrute. As the microbrute is a scaled down version of the minibrute, I assume the electronics are not that different. So you can have a look at the minibrute schematics to see what is used.

Hope that helps,
Albert

Just noticed that the schematics of the microbrute are now on his site too.

The VCO, VCF, and VCA don't use ICs*. They're made from discrete components and they're designed by Yves Usson, except for the VCF, which is based on the filter in the Steiner-Parker Synthacon.

*There probably are a few ICs there, such as op-amps, but no oscillator, VCA or filter ICs.
