Hey Tony,

I use the T4 in multi finger mode. here you can make 1, 2 3, 4, note chords. Roland uses a slightly different chord recognition system in their "easy" or "intellegent" mode. This is not a problem when using the accordion because it makes 3 and 4 note chords. The difficulty occurs only when playing the BK-7m from the T4.

I'm not a pianist so when playing chords on the keyboard I take the easy way out.

About the thru box, I thought it sounded like it should work, but wanted to hear someone else's view. Thanks for your response.
