Are you seriously comparing a stereo mp3 player which has midi implementation to the LP-16 multitrack player and not latest your device cost twice?
I don’t think it is fair to compare a completely different device just because it fits better to your needs.
I’m really sorry to hear that the LP-16 does not fits to your needs however there are at least couple of thousand other user who is happy with the device.
As I am the only one who is handle support requests I’m wondering who told you that the device supports midi clock? Do you still have this email?
