Sorry, Donny, but have you ever used the Roland Chord Sequencer? It really IS hard to realize how useful it can be until you have used one for a while.....

When we all say 'my style of playing'. despite how different it can be, one thing in common for most arranger players is that we are forced into playing (I don't count hitting the right chord at the right time 'playing' - that's just an input source for the arranger's brain!) with ONE hand! This is SO different from truly playing keyboards.... two-handed arpeggios - forget about it. Two handed funky syncopation licks - forget about it. Extensive use of the bender - forget about it. Etc., etc..

All of these are legitimate techniques that you are expected to do as a keyboard player. But buy an arranger, and you might as well lop off your left arm, for all the PLAYING it's going to do.....

There's a very easy way for you all to check this out.... Use your arranger's sequencer to record just the accompaniment for a favorite tune, for at least a couple of verses and choruses. Now play it back, and play over the top of it using two hands.... either a whole keyboard piano, or a split with a solo sound and a nice comp in the left, whatever you feel like. Unless you have NEVER played anything other than an arranger, you are going to sound better, and re-familiarize yourself with playing techniques you may have forgotten since your left hand got tied down.

Now imagine that you can do this any time you want, and STILL not have to give up the freedom of arranger play and use SMFs....... DON'T let the mechanics of chord triggering make you forget how to play well with BOTH hands..... DEMAND a chord sequencer from your manufacturer, and watch how much better you play and sound.......
