(1) In Sequencer mode, the sounds are plunky and thin. All the preset sounds are shallow and heavily trimmed in SEQ. They sound lifeless, especially the pianos and winds. Why are all the effects stripped away in SEQ? Is this normal? Can I somehow access and work with the preset Program sounds (effects included) from SEQ?
(2) I can effectively alter the EQ, Trim, and RealTime controls in SEQ, but I cannot utilize the IFX or MFX controls. I can access the IFX Setup page and manually apply effects, but it makes no difference in the sound. Same with MFX. TFX is the only FX that works. Why don't these controls work in SEQ? How can I use them? Is there a hidden switch inhibiting them from working?
(3) KARMA does not work in SEQ. If I press the KARMA switch, the pads will utilize KARMA, but all sound disappears from the keys. Why is this happening? How can I use KARMA normally in SEQ mode?
I am not even close to being familiar with many of the technical functions on the M3 thus far, so if you have instructions or advice I would really appreciate hearing them in language a simple musician can understand.

I'm getting very lost in SEQ, which isn't good. I need and would appreciate as much help as possible.
