EXS 24 Logic Sampler Users Group

I downloaded the update to LAP 4.7 today from 4.6.3, when I 
loaded songs previously done in 4.6.3, all my EXS instrument 
tracks played at different tempos, for that matter, it appears to 
have completely wrecked my Unitor MKII, as no midi notes are 
reaching my physical synth modules. 

If I disarm the new midi engine and use the classic, everything is 
back to normal, anyone else fiddling with the upgrade?

It also seems to have crashed a Virtual Dongle EMU I have been 
using, Virtual Dongle EMU 1.3.4.

I am using a G4 Dual 533, with 512mb ram, Unitor MkII is 
connected via a G4port serial connection, and using ADB dongle 
via Griffin Imate. Mac OS 9.1.

Thanks

Wierd, my set up is very similar and nothing seems to have changed?????
