Hello!
Last night I rewired my studio a bit in order to answer a question I've long held: would sending digital 8-track (software synths, baby!) out of my sound card, into outboard tube gear and wonky-ass 1980's mixers, then back into the interface add any sort of magic?
Check back later tonight to find out! I'll post up pictures of the signal path, and I'll be uploading two waves to my soundcloud: one of the sound sample mixed in the box, the other of the same sound sample 'farmed out' to outboard equipment.
I've already tried this to a smaller extent: I've been piping Kontakt 808 through the Manley Vari Mu.
It sounds heavenly...people think it's an actual 808!
