Yet More Problems with the X1

So now, when i drop a sample into one of the sample slots, it plays in the sample slot but with no bass. It's like the filter is on it but it isn't.

Problems so far -

1. Sometimes my first X1 controls 2 decks at once!

2. Can't get the 'Addon Mapping from NI' to recognise itself for controlling decks C & D!

3. Orange 'midi light' is on and not Blue, Yet the midi light flashes when i press any button or knob so i know they're both working.

This has become an absolute joke. I've spent days trying to sort this out now. All i want is 2 X1's to control 4 decks in TSP2. 1 for decks A & B and 1 for decks C & D (sample decks).
