Welcome, Tom.
I'm not sure what you mean by "crooked", but you don't really need a map for EZD.
Especially if you are playing its own patterns. You can use one of the GM maps if you want to.
Did you insert EZD as a soft synth in your project?
Is the output of your MIDI track set to EZDrummer?
My guess is that the MIDI track output may be set to the MS Wavetable Synth, which will sound noticeably different.
