Found out today that Roland has discontinued GR 33 even though it was introduced after GR 20. Maybe the decision of the marketing department in their firm.
There's a new "VG-99" as well but don't know what exactly it is.
Had another query. I heard that it does not matter what the tuning is on your guitar - the synth can track notes properly and sounds alright even if the actual tuning is way off. By corollary, does it mean that one can put high E string instead of all 6 strings? I know it might be a stupid question - but if such a thing is possible then playing becomes easier and tracking faster because the same number of cycles can be tracked in lesser time.
(Hope my queries are not excruciatingly boring!)
Cheers
