Subject:[sdiy] How DCOs work

 I found this video interesting. It explains how DCOs work and the
differences between the DCOs found in the Juno 60, 106, Akai AX 80 and
the Kawaii SX240...

He shows how some DCOs are “more analogue” than others, due to the
implementation of the master clock.
He then goes through the schematics of said synths highlighting the
relevant circuits.
At 29:00 he asserts that an inverted sawtooth sounds better in the
bass end than a regular sawtooth - I’ve never heard that before.

Tom of course has a great page on the Juno DCOs

I guess the most recent application of this technology is the Deep
Mind 12

AI

p.s.  he also has a great video on repair/modding an Akai AX 60 - it
looks simply stunning with red LED faders!
