Sorry my dear Kn-fan.U have been playing Technics boards for last 15 years and u have
a little knowlege about the sequencer.I am
sorry i dont know what models have been with u.

I have kn6500 and it has the best sequencer i have ever had.Regarading the loop
wihch,i think is the most imprtant function
is available in 6500 in all the sections
for example in easy rec mode,in multi and
ofcourse in making your own patterns.

KN6500 is realy made for pro song maker
it gives me a lot of pleasure when i compose
my song and the best editing functions.
Ofcourse the Kn7000 also has the same os.

Do not waste your time go for Technics.
and it will become your better-half,I hope.
