Thanks to everybody for their help here (my first post). I should have explained that I like to play blues, jazz and rock using a Roland FP4 and playing left hand bass and right hand piano.
I want to add another keyboard on top that will give me great guitar sounds, then I can use a pedal to pitchbend.
Being disabled, I am unable to carry equipment and rely on others, so the less weight the better. Also, I had a PSR S900 but couldn't see the screen so sold it on. Looks like a Tyros could do it for me then?
Any future comments will be greatly appreciated. Thank you.
