Nava Hi-hat and Ride problem

Postby zener » Aug 12th, '19, 19:36

Hi all,
my nava has a problem with the closed hi-hat and ride sounds.(I don't remember if this also affects the open hi-hat it probably does)
When the unit turns on and I start a pattern these two sounds have a bit of delay to reach full volume (like someone slowly rises a mixer fader).
After they reach their full volume they behave as they should.

The two sounds seem unrelated circuit-wise so I can't think of a direct connection but I haven't properly looked at the schematics yet..
Since the build is relatively new (about a year or so) I wouldn't suspect any of the capacitors either.
Although a capacitor problem was my first thought since they can exhibit similar behavior.
Still, the capacitors that are there are almost new so too early for them to fail I guess.
Another thing that crossed my mind is some kind of logic chip issue but I think these things are mostly working or not so I would suspect something analog to be the culprit here..

Anyone has any ideas what might be at fault?!
One thing I thought about trying first is replacing the 5218 chips of the failing sounds with the ones of a good sound but of course I'm open to suggestions.
Thanks:)

Did you solve the problem with hi-hat and ride?

I have almost exactly the same trouble with mine Nava 909.
Everything worked perfectly the first six months, but then the crash stopped working, before the hihat and ride and got wierd, just like you described.

Totally forgot about this thread.
The problem in my case was a bad 74hc595 register in the accent circuit.
Replacing it fixed the issue.
I've also gone further and installed the mux boards which address the accent issue.
