X1 d killed the ability to fastbounce timecode/tempo based plugins. (antares, melodyne, waves, gtr rig, etc. X1 d crashes WAY more than 8.53. Simple things like deleting a midi clip with a midi fX on it will fatally crash sonar. Same for dragging midi fx to/from bins/clips. Transient detection with clips is NOT consistant. Plus Audio snap has horrible 99.9db noises on all audio tracks enabled with 'clip follows project tempo' after you've changed your tempo and click around the timeline. I was told in a an email to 'stay tuned an update is in the works' but now Cake has pulled the 'Bait and Switch' trying to say that the customer service rep was reffering to melodyne having an update in the works. Funny thing is, CLEARLY he was NOT speaking of a melodyne update as he even stated that there were issues with Melodyne memory leak but noted that WASN'T the problem I was having. My problem was the X1 D patch killing the fastbouncing of ALL timecode based plugins. Cake needs to fix X1. Or, All of us Cake users need to stand up and agree to NOT upgrade. I don't appreciate being lied to. Even the phone support team (which SucKs and know very little of the product, features, how to use them, or what works and doesn't, or how to work around what isn't currently working) indicated that they were fully aware of the problems and assured me they were working on them. Apparently Cake was working on the fixes just NOT for X1. 2 years after release and X1 still can't hold up. Hasn't been updated, has been left UNABLE to fastbounce timecode plugins. Very Crippling. Doesn't leave a good taste in my mouth NOR the confidence in Cakewalk to want to continue finacially supporting a company that SCREWS there customers KNOWINGLY. When was about to come out, my confidence in Sonar was high and I whooped out the debit card without hesitation. Still Pro channel problems, audio quantize didn't work till X1 C. and then the X1 D disaster. In fact I have the $99 waiting for Cake (If they SHOW a little customer support and company responsibility by updating X1 with a MUCH needed patch) and quite frankly I need the Tax right off. I imagine others having the money and wondering IF they should invest in an un-supporting company. It makes better business sense to support what you put out. Then, customers will give you their FULL financial support.
