I uploaded dj2go3.xlm and dj2go3.js last night. I think we're getting closer to the vinyl feel actually. I think the speed (and subsequent pitch) aspect is almost spot-on for a "vinyl feel." It would be nice if you could get a second opinion though (*cough* *cough* tboy) apart from my own, as it has been a while since I have been behind turn tables. I just wish the response could be a little "tighter" so-to-speak. Sadly I think that's probably an inherent "problem" with the overall interface (and not one that scripting could necessarily fix). Overall I'm very satisfied with this setup.
The enter button still triggers the low pass on deck a... Not that it's a -problem-... I actually am starting to enjoy that feature (I almost wish the back button would also trigger LP on deck b lol). I just wanted to point that out because you mentioned wanting to submit the .xml and .js to mixxx... As a part of their general practice, they won't post it unless it's 100% functional as it should be (in theory anyhow). Speaking of getting things functioning, do you plan to tackle the (+) and (-) pitch buttons on deck a and b eventually?
On a side note, I tested it with 1.10.0 beta last night. Still works great. Though my beta test was brief, everything seems to be stable. I want to test an hour long set on it (while using my VST being controlled by a midi controller) to see if it will crash (like it did with 1.9.2). In regards to 1.10.0, the sound quality is notably improved! Listening to my 24-bit .wav tracks through my Sennheiser HD-280 pro headphones, you can tell a notable difference in sound quality. I look forward to when they release a stable 1.10... Though I am going to set how stable it is and I might use it for my next gig on 12/22; though I wouldn't recommend anyone else doing that necessarily. I will have to do further test to determine if this is possible, but the initial test runs were promising.
Lastly, is there anything else I can do to be of service, aside from testing the scripts? as mentioned I personally really appreciate your efforts. So if there is anything I can do, let me know.
