Bonjour Bastien,

The accent is a part of the volume envelope of the sounds, at the
service manual in page 10 you will find a section marked as "Env Gen". A
little to the left   and above there is a section "Accent CV". You can
see that the accent voltage is fed to all the instruments from one bus.
I think that those two instruments would not work at all, if traces on
the pcb would be broken.

So maybe you are falling over a usage error. Are you aware that there
are two "snares" and snare 2 with accent has quite the same level as
snare 1 without accent

See owners manual, page 10 ff
