Curtis Electromusic (CEM)

This is not an official site for Curtis electromusic, I have only scanned parts of their info papers for fun. If somebody is offended by this (Curtis ?) please let me know and I'll remove everything.

In fact these pages are somewhat obsolete, more info about Curtis is available at The synthtech page Check it out!!!

These chips were used in classic analogue synthesizers, for example in the Oberheim Matrix 12 / expander. The linearity and temperature stability were excellent. The chips are no longer manufactured, but some distributors still have most of them in stock (but for how long?). Onchip systems (the major distributor) have stated that they will manufacure more chips when they have preorders for at least 25000 pieces.

One of these distributors is OnChip systems:
