The CS6 is a great sounding machine; however, when in use the arpeggiator hesitates something like a 32nd of a note from note on events. This is definitely a design flaw as EVERY other CS6 user will attest. Please, Yamaha, do not allow this error to ruin an otherwise superb synth. Please do whatever it takes to correct this bug. As it stands, the arpeggiator is quite useless in most realtime applications, and I'm quite amazed that it passed the testing dept.. Keep up the good work..
