In order of ascending Annoyance: The Alesis 3630 "Compressor". I use the term loosely. The MAudio Delta 44 I/O. As others have mentioned, it was a formidable looking ribbon cable and patch box and that was about it. If I could only have found a girl who was impressed by such things... I would have sold it to her. Cakewalk "Guitar Studio" This early software DAW was marketed to guitarists as a sort of "Cakewalk Lite" product. I foolishly bought it for sale discount, and found out it had latency that can only be termed "glacial". I kept foolishly hoping Cakewalks famous "Great product support" would kick in and there would be a wonderful update. Never. Not one. Not for as long as I kept that damn thing around did they ever produce so much as a minor patch. I never bought another Cakewalk product, on principle. Behringer "Feedback Destroyer". This was a sort of automatic EQ that would supposedly sense and cut frequencies that were causing feedback. Since I was playing a lot of single shows without a soundman in a particularly bad room (300 capacity, shaped like a large horn with very low ceilings and lots of hard reflection, oh dear) it sounded like an idea worth trying. It wasn't. This piece of complete trash was intended more for live performance than studio work, but it certainly was useless for either. In it's "automatic" mode, it needed to be reset every few minutes or it would select and cut frequencies with mad abandon until it just sounded like you were fading away. Well, enough about that. The lights were sort of pretty though. Korg D888 an 8 track hard disk amateur-grade DAW. It really would have been pretty good if not for the pres, which were From Hell. They were either off or full on, clipping hard. If you fiddled with them enough you could get them in a sweet spot from which you could use an attached mixer to bring your signal into somewhere near the level you wanted. Maybe. And of course add to the noise floor while you do it. Junk. Bottom line: you get what you pay for, sometimes. These were the products that taught me what I should have already known: never be afraid to pay extra for a good pro quality tool.
