I haven’t tried the HL in bass mode on guitar, but it’s worth a shot. I noticed in the suite software that guitar mode has the same setup parameters as bass mode, so I don’t know if there’s something else going on behind the scenes or if the modes are simply labels that make it easier to identify what settings are for what instrument, when you load saves.
I relate to what your saying, as easy as the software suite is to use, it would be nice to be able to rip off the bass board and put directly on the guitar board, without the software in between. I’ll give it a whirl, on my next go around. FWIW I have all three settings set to fixed attack with adjustable release. I’ve been meaning try the factory default mode on guitar. I’ll report back on this.
