UD,
You mentioned that you hardly used the arranger and your laptop is playing all the sequences .
How do you compare midi sequence playback on any of the keyboards you have played vs. the sound card on the computer?
Doesn't the sound card dictate the playback or does hooking the lap top up to the KN7000 make a difference ?
You could make audio recordings of your sequences and put the on the SD card , is that something to think about ? Dan O'
