Can't record bass guitar in GarageBand after OS upgrade

Hello!!.

I've recorded a lot of tracks before using the same setup (GarageBand + Scarlett 2i2 + external headphones), then all of a sudden after macOS and GarageBand update, it stops recording my instrument with bass sound, for example a TUBA. If I'm playing a saxophone it works propertly, but bass sound did not record.. I've googled and tried various solutions, but nothing has worked so far. I can see that the Scarlett is reacting to my play, so it's unlikely to be a hardware issue. My input device is set to Scarlett Solo and output to external headphones, but of course, I've tried adjusting these settings without any luck. Any ideas?
