In addition to Chysn's suggestion, you might also want to calibrate your pitch/mod wheels. Here's the procedure:
Wheel Calibration Routine:
1. Turn the mod wheel all the way off (down) and also hold the pitch wheel in the down/off position. While holding the wheels, press and hold the Compare switch and press the Arpeggiator switch while holding.
2. Return the pitch wheel to center, press and hold the Compare switch and press Osc switch while holding.
3. Move the Mod wheel all the way on (up) and while also holding the pitch wheel all the way up/on position, hold the Compare switch and press the Sequencer switch while holding.
