I had the same result (doubled notes) when using the default midi input ("all inputs omni", I think). If I change that to the actual midi keyboard input I use, I only get single notes. Something being echoed? I haven't found out. There's a CAL script, undupe.cal, that will easily fix already recorded doubles.

As well as Wavelab, the time stretching/shrinking in Izotope RX is pretty good. Uses the Radius algorithm, FWIW.

I run both those plugins on a Win7 machine with no problems, albeit with 32 GB of RAM. Don't think the OS is your problem. They do seem to be greedy, so maybe more RAM is worth trying? But a single instance on a track vs. a single instance on a bus wouldn't make any difference to the resources needed, would it? Multiple track instances, yes.

Thanks for your reply. I found some information here: http://www.cakewalk.com/Documentation?product=Cakewalk&language=3&help=Introduction.30.html#1538285 about installing. To be clear: I need to use Bandlab Assistant, find the setup file, then move it to the DAW? I can't download the setup file directly? Cheers.

Thank you for enabling offline authorization. As my DAW computer is permanently offline, what is the process for downloading and installing this version? Can I directly download the installer on an internet-connected PC? Thanks.

Wow, this is an long standing issue, and surprising it hasn't been addressed since 2015! http://forum.cakewalk.com/Sonar-IpswichLexington-Users-Remove-DC-Offset-During-Record-Heads-Up-m3337455.aspx

What are you using for live input? It's plugged into the MIDI input on the UMC404 (not directly connected via USB)?

I use Voxengo Sound Delay, a free plugin, for this type of thing, e.g. aligning a mic'ed bass guitar with the simultaneously recorded DI track. https://www.voxengo.com/product/sounddelay/ Should work for your chorus effect?

OK, what is your "goto DAW", if not Cakewalk?

In the View menu, open the Markers view. Highlight the marker you want to delete, hit the delete key. There may be other ways...?

We're talking CD-Text which some standalone players will display. I think most computer media players do show it. https://en.wikipedia.org/wiki/Cd_text What program are you using to burn CDs?
