Hello,

About to finish a fully working NAVA!
Last instrument with a problem is the RIMSHOT : No sound on output (main & dedicated)
After some tests, it seems that there's no signal (on scope) on J4 (on the main board).

i've measured all the different labeled points of the instrument on the PCB (see below).
I also have some signal on the rimshot volume pot (pins 2 & 3).

Here are the other measurements of the Rimshot voice :

TRIG point


ACC point


ENV point


F1 point


F2 point


F3 point


What should be the next thing to check ??

Thanks !

After debugging the issue with the schematics, i've found that there were not continuity between C122 and NON_INV_INPUT2 of IC50 (see below)
By looking more precisely to the joints of IC50, i found that one of the pin was not soldered...

so I've soldered the missing joint, and got now a fully working NAVA !!
