Juno 60/106 DCO differences

Post by nSCOURGE » Sun Jan 18, 2009 10:56 am

Too much OT c**p, and NAMM traffic going on at Harmony, so I firgured I might get an answer here...

How would any of you in the position to know, subjectively characterize the DCO differences between the JUNO 60 and the 106(given that they use different chips)?

Would the same patches sound nigh on identical(except for subtle differences in the characteristic tone of their respective instrument - punch, warmth, etc.)?

Thanks.

So let's start by getting a couple of things on the board out front. The VCO, VCF, and VCA circuits are nearly identical.

I used to have a Juno 106, and have played many Juno 60s. The differences in sound are subtle. The infamous filter in the 106, the 80017 chip, is actually the VCF and VCA chips of the 60 combined in one chip. DCOs on both are identical.

What about the envelopes? Aren't the 106s software generated whilst the 6/60s are hardware?

Correct. The Juno 6/60 uses the IR3R01 envelope generator, which is the same thing used in the Jupiter-8. The 106, like nearly all the rest of the Jupiter/Juno/JX line, uses software envelopes.
Switches, knobs, buttons, LEDs, LCD screens, monitors, keys, mice, jacks, sockets. Now two joysticks!

Cheers - I wasn't completely sure. :)

And the arpeggiator vs. portamento? There are certainly a few key differences.

That is an excellent analysis. Puts paid to a lot of conjecture that's been posted over the years.

Interesting about the Bass Boost being a Sallen-Key design. That's what the Korg35 filters on the MS10/MS20 are. Don't several Roland synths have this? MKS-80 comes to mind. Alpha Junos, may as well.
I am no longer in pursuit of vintage synths. The generally absurd inflation from demand versus practical use and maintenance costs is no longer viable. The internet has suffocated and vanquished yet another wonderful hobby. Too bad.
