I have a friend with a ZR-76 (Ensoniq). We both feel the sound could be improved with a pre-amp and were wondering what you guys are using. Do you recommend something like a dbx586(?) with tube warmth and digital outputs? (For digital tracking.) Do you use stereo pre-amps and slightly vary the left and right outputs? Or set them the same? In general, it will be applied to the entire (sequenced) mix. Your opinions would be very interesting to us. Thanks very, very much. D.
