Doug Curtis is dead.  Ron's dead.  These chips were designed by the
old guard, and they're heading to retirement, and universities aren't
teaching the old analogue chip design ways anymore (everyone wants to
design high speed digital silicon or GHz RF).
Uli isn't interested in development, only copying (too costly).  Mary
at CEM is just selling her husband's legacy.  Not sure about Alfa.
SSI is the one place where I hold out hope since they brought together
the old guys and some cash.
But building synths is a tiny market, really tiny.

Yes that is a draft/preliminary version.  I believe they will be
releasing an updated version once the chips are ready to ship later
this month.
