[sdiy] How DCOs work

[Adam Inglis]

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

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