than AD633 but it has four multipliers in package! Thanks for the hint,
somehow I missed that chip. Not that I will use from now on, but that
inspires to make things like Chebyshev polynominals generators, or
analog IIR filters (who would want that anyway), modulation arrays. But
still it's a lot of bux.



Hi!

A lot of the multiplierchips out there are very expensive, but on the
other hand you often doesn't need that many multipliers in a synth...so
just order a few samples of MLT04 and experiment away!

btw, I recently discovered about ten XR2208 (operational multiplier,
high frequency buffer amplifier and OP) in some old discarded phase
meters for audio...could be useful someday..
