Harrison has said that build 1610 has introduced some bugs with track ordering and most people should use 1508 for now. Are the people here that are having issues using the interim release 1508 or the 3.0 release? I have noticed a huge improvement with 1508.

i'm waiting for controller support to be re-enabled...

Did my first real mix with MB3 yesterday (interim version 3.0.1610 ). 
 
This project was made up of 9 drum tracks, one bass, three guitars, a strings track and a Vox track. And one MIDI track using Ivory.
 
I just used MB FXs with the exception of Relab's LX-480 for vox and snare.
 
I had one anomaly. At one point I closed & saved the project and I got a "Mixbus stopped working" message. After clearing that message by closing the program, my changes were there after the next open of the project.
 
 

1508 on my Win laptop and it has managed to squeak out 30 tracks of audio and plugs w out and problems …
I'm staying put there for now until Harrison has a Win update that is cleared and good to go all across the board as opposed to 1608 …specific fixes w a warning not to go there unless you need the fixes in the update … 
 
1608 on my i Mac …works like a charm over there ….older machine , lighter spec , less ram ….chugs along much better than I had expected ….1608 definitely fixed a few issues for me in that OS 
fwiw….my setup would be classified as hobbyist right now so I may not of pushed in areas a working studio or user may have pushed ….
Over all I'm very pleased w MB 3 and I look forward to them sorting out a few of the left over  kinks some folks are having ..

They are working quick and making good progress. I couldn't ask for more than that.

Started happening more frequently (like 4 out of 5 times).
 
I think this might be related to changing the Group view as Ben said that 1610 introduced a problem with what now seems like groups/tracks.
 

Could be. I haven't used it at all so I haven't reverted back to 1508. A newer version is probably right around the corner...I'll wait.

Where do you guys download the program from. I bought v1 ages ago but can't find a user area.

Thanks for this.  I am waiting for the official (non-beta) release; I am letting you guys be the testers.  I may yet give in and try out the interim release given the positive results some of you are having.  Do hope that the bugs are getting fixed and that an official release is coming; yet, I would rather them get it fixed than be premature with a faulty release.

There is an "Interim Release" subforum on the Harrison Mixbus Forum; however, you have to be a registered forum user to view the Interim Release area.
