Well I finally got my ESI upgrade. It took a long time but I got it for free from EMU. Only because I have the ESI 4000. Contact the service department and be persistant. They get piles of mail every day and don't read most of it. Don't expect immediate results either. BTW the upgrade works fantastic and so does Recycle 1.7. The ESI 4000 Combined with Recycle, Wavelab 3, ACID PRO 2, Cakewalk Pro 9 and a mass of plug-ins enables me to make the tracks that I was just dreaming about years ago. My music has come alive with SCSI and a sampler!
