ahh, why does cubase need to go and not support AUs. as for the reaplugs, that was my first port of call for getting an IR loader for OS X. alas, the plugins are windows only. i didn't actually try to download the binary for OS X, but i'll give that a try. when i'm not running windows (trust me to be running windows when someone maybe finds exactly what i've been looking for, for ages..)
thanks,
