Unable to use import or drag & drop in Cubase LE4 with EZ Drummer, I found a “work around” that works for me.
While playing a drum track in Toontrack Solo I patched the headphone jack on my studio monitors to inputs 1 & 2 of my Alesis Multimix 8 USB
mixer which I then “recorded” in Cubase LE4, leaving me with 2 nice drum tracks.
I would imagine this would work for any mixer used with Cubase LE4. Make sure of course you unplug your mixer from your studio monitors
while you do this to eliminate feedback, I monitored the process with headphones out of the mixer.
