Disables effectors
Effectors init order should be distortion->chorus->flanger->gargle->(loops)
Should work quite reliably for any version of IIDX27-31
Leaving out IIDX25-26 until I make sure patch doesn't cause video playback to break
distortion: E8 4A A2 00 00 90
chorus: E8 9A 99 00 00 90
flanger: E8 CA 89 00 00 90
gargle: E8 AA 82 00 00 90
