I’m fine with the level, I keep the main volume and VCA ENV at 0dB 95% of the time. No noise issues. They already made it louder in a previous firmware update. I’m worried if they make it louder it could affect the internal gain staging and lead to easier internal clipping etc.
It might be a bit lower than some other modern synths, but I’m used to dealing with real instrument level stuff like guitars, basses, and Rhodes so it’s really not a problem here. I give it some gain with a TG2 pre/DI to get it to around -18 dBfs average levels for recording.
