Hi Guilherme,
triggering tabwrite~ with bonk~ may help you get rid of silence _before_ the
after the note I'm not sure...
Personally I would just leave that.
What's the reason you want to remove the silence ?
You could also detect silence on the sound itself with an envelope
off the top of my head: [abs~]--[lop~ 100]--[expr~
$v1<0.05]--[unsig~]--[change]--[tgl] or something similar ?
