Curtis Analogue Synthesis Chips

CEM = Curtis Electromusic Specialities - s special analogue small scale chip. by Doug Curtis (died 1/2007)

after the death of DC there are a number of clones available by ALFA and Behringer/Music Tribe under the brand of "Cool Audio". There is also: "Sound Semiconductor" OnChip - is the last one remaining after SSM/Curtis as the old one - strangly. atm it is easy to pick up one of the first 3 right now - ALFA has them for about 7€ per item which makes it totally possibly to make analog (poly)synths again in 2018 and later.

where to get CEMs

- Dave Smith has a special amount of CEMs for the Evolver series (new ones) but its unique and a special deal... so he will not sell them
