Sorry to hear that
Would you be so kind as to report it here http://forum.cakewalk.com/Problem-Reports-f77.aspx
 
I have just tested Korg M1, Arturia's Wurlizter V, ASS Lounge Lizard session and True Piano's and the sustain off my M-Audio Keystation Pro 88 works as expected.  Set to a none specific midi omni input.

What Keyboard are you using?

I'm working through my instruments...so far (even in JP) IRIS2 is the crankiest. The sustain pedal isn't working for anything though.
 
The keys are an AKAI MPK88.
 
I've opened a ticket, but I'll drop something in the forums as you suggest.

Some VST3s (example: AIR Loom) had a significant input echo delay

 
This fix in Kingston appears to have corrected the WSOD I experienced with the Virus TI control VST3 plugin.  The VST2 version seemed to be okay regardless, but the VST3 tanked old projects in a few seconds flat!
 
Thanks Cakers!

The verbose installers are still a PITA (very confusing) but at least they work I suppose:

Thanks.

Siento que está teniendo tantos problemas con Kingston. Se ha trabajado muy bien para mí hasta ahora. Espero que encuentre una solución para ella en breve.

Nice to see that the instructional videos in the CCC are now available for 64bit Windows.

 As for the problems themselves: The only change to the system in question was Kingston. Symptoms: no sustain pedal on any instrument (verified it works with stand-alone plugins and two other DAWs), and IRIS2 just outputs hissing on the left channel and bit-crunched noise in the left channel.
 
Rolling back to Jamaica Plain solves the issues with noise and plugin instability (since IRIS2 has a 100% failure to load rate for me in Kingston), but the sustain pedal is still MIA. Weirdly, my Imagine-Line plugs (notably Harmor) appear more stable.
 

I had the sustain pedal issue and bitcrush noise on some plugins (Addictive Drums 2 namely) when I tried out the update yesterday for a few minutes, but oddly enough while my sustain pedal wasn't working, the pedal I had set to output sostenuto was acting like a sustain pedal while using Lounge Lizard EP-4. Not sure if it's only on that plugin though, since I didn't have a chance to check and test out other vsts before heading to bed.

I don't mind that Kingston is being weird since JP works great on both of my awful systems, but it was nice being able to see how fast Kingston loads things up.

Has anyone tried Sylenth1 with this yet? I get incredibly loud white noise in the left channel and heavily distorted playback in the right channel. I tried other VSTs, and those work fine. Very frustrating and unfortunate as I use Sylenth pretty regularly.

I'm having exactly the same issue with Synthogy's Ivory 2. Guess I'll have to roll back to JP as well.
UPDATE: Rolling back to JP solved the issue.

I just did a quick test of recording midi and it recorded the pedal correct for me.
 
If it is not recording sustain pedal at all check in the preferences under midi playback and recording to make sure that the to record controller is turned on.
 
I have not had time to check all my synths yet so I may still find issues.
