I tried almost all riffers in the market, and it seems to me that only a few can be useful to create guitar arpeggios/riffs in the rock, jazz, blues area:
ChordPotion is the N. 1 to me, but I suspect I can do the same with Scaler and this trick
Riffer is the N. 2, but using it to build convincing guitar arpeggios/riffs is hard
I also tried Cthulhu, Midi Madness 3, Phrasebox, but I find their patterns too much āmechanicalā
most plugins I tried seemed to be more suitable for EDM, trap and similar plagues
BTW, if developers were able to make videos with different styles, not āEDM, trap and similar plaguesā as usually happens, it could be great for us old dinos
