Scott, I like a lot of the things the PSR2100 has and does, along with a few things I don't like...Can you edit a GM drumkit on the Tyros[user], or edit a user drumkit and remap it to a GM location for SMF playback? Tell me the reasons I should get a Tyros? I know you said it has 4 playback markers as does the DisCover5 in SMF play..Does the Tyros read a SMF and show chords in the display automatically as the DisCover 5 does? I know the 2100 can but you have to enter the chords..I do like the harmonizer on the 2100[it seems to be better than the2000], is the Tyros better? Is the keyboard[Tyros]key feel like the Pro[DX7 type]? Does after touch work well and assignable to many applications? Can a volume pedal controll expression to any assignable part, or does it only work globally? Give me your top ten best and worst things about the Tyros..Since I have not checked out a Tyros yet, I would value your comments....Anyone else too..
