I really didn't have much reason to believe that the GW-7's sequencer would be any different than the EXR-3's sequencer,which is to say,you could not control volume and pan AFTER the recording of tracks was concluded.
I called up a Roland rep to confirm this and he said " Well,what do you expect for a keyboard(EXR-3) with this low of a price?" And I answered "Well ,I expect it to have basic editing functions like volume control and pan. My Casio does and I only paid $300 for it."Right after that,I heard a rather pronounced "click",like the phone was slammed down or something.
I don't know,definitely,one of Rolands "lesser lights",and a surefire candidate for the Dale Carnegie Course.

Now if someone can come forth and honestly state that the GW-7 can do 16 honest sequencer tracks with the ability to control each part,pan and volume wise,I'll stand down and *corrected*.

I am well aware of Rolands reputation as per their products so even they should be
concerned that an instrument that claims to be able to do 16 tracks CAN'T do the pan/volume thing.Hopefully,this error has been remedied in the E-09 and the Juno-G.
