as history already tells us, there are thousands and thousands of synths still in use based on CEM ICs; when the market gets thirsty enough to justify the massive expense of another run, it will happen and dead synths will be resurrected for a nominal price. last i heard, OnChip (owner of the CEM designs) requires a minimum order of 10,000-to-25,000 chips. ever wonder where all of those CEMs in every DSI Evolver came from? sweet, sweet money! of course, all of these chips pop up from time to time, and i think synthtech.com has many.Dirk wrote:All chips have a limmited lifespan of about 30 years, so in about 10 years from now all CEM and SSM synths will breakdown.xpander wrote:higher-end synths based on Curtis Electromusic CEM chips will be more future-proof than ones based on custom ICs; you can be pretty sure sooner or later someone will have popular CEM chips fabricated once enough synths are dead until replaced- esp 3340, 3374, etc- the common ones. i assume older synths based on discrete components and common ICs will be much more service-able even if an exact component goes out of production.
i definitely agree that buying one of the high-quality analogs on the market today is a great way to postpone your worries for a couple decades.
knowing what's under the hood and keeping backups of rare parts for the inevitable rainy day is a great idea, too.
Discreate synths will outlive the chip synths.
my point to the thread is that the common CEM chip-based synths are going to be safe in the long run due to a large enough demand (read: money) for periodic manufacture. similarly, synths based on less popular proprietary ICs are at high risk for becoming obsolete unless a small group of users are willing to split the cost of a huge order.
