Question for guitar synth users: Why guitar synth over having an actual synth keyboard to the side?
I've tried a guitar synth once, don't remember which Boss model, it's been many years now so probably not the latest. For me the big problem was adapting to play it like the instrument in use. Guitar -> sax sounds is pretty straightforward, but e.g guitar -> keyboard type instruments was more difficult. It felt a bit weird to play guitar like that.
For me it's just easier to use an actual keyboard for that stuff, plus not worrying about any of the guitar synth quirks like tracking etc.
