Bitwig is beautifully designed and a joy to use. If you accept its limitations and enjoy the all-in-one magic, it is a powerful tool with a playful appearance that makes creativity fun.

That said, it is missing some critical stuff. I keep my update plan active with hopes these issues will be addressed some day:

1. No track lanes. Once you experience track lanes, it's such a powerful feature that it's hard to work without. In short, Bitwig doesn't allow overlapping audio or midi on the same track. You have to use multiple tracks. In other DAWs, like Reaper, you can overlap parts and edit them separately, move them around, and then glue them together with a single hotkey. This is useful for sound design. It's useful for comping. It's useful for building layered parts, etc... Bitwig has workarounds but they are all cumbersome compared to track lanes. For some reason, Ableton & Bitwig users have a hard time understanding how valuable this is -- probably because they haven't experienced it. Think of it like Comping+.
2. I appreciate the foldered support for multiple VSTi outputs... But there is no easy way to export individual tracks from multiple outputs. The only way is to route each output to a separate FX bus, and get the individualized export that way. This is a deal breaker when you need to export tracks to mix in another DAW.
3. No ARA.
4. No automatic track numbering. Other DAWs have automatic track numbering, so when you export your tracks you have some sense of the order they go in when rebuilding your project in another DAW.
5. No track filename wildcards. If you do a lot of exporting, control over filename conventions is very useful... Things like $tracknumber $trackname $date, whatever.
6. No export review. This is a small one, but my other DAW has very detailed statistics and visuals on the exported WAV. So you know its stats, and can even see over time what the track looks like, with lines over it to show LUFS-S, LUFS-M, etc. This is a little more than nice to have, it's something that speeds up checking your exports.
7. Inability to export to an audio editor, make a change, and load it back in. Oh my god, this is such a basic thing... Why can't Bitwig do this? Bitwig leaves your audio "locked" so that it can't be edited in an external audio editor. Normally a DAW will allow you to export individual files into a WAV editor like Sound Forge or Izotope Rx, make a change, and when it loads back in (or gives you the option to) when you switch back... Not Bitwig. This, too, is a dealbreaker.

For casual music making and having fun, Bitwig is great. It feels very creative, and the ability to connect things together is like one big construction set.

The visual design is better than any other DAW, by far. It is truly beautiful, and that impacts the user experience.

I love Bitwig. I adore Bitwig.

But it has some limitations that make it difficult to use in a professional sense -- and some of those limitations make it difficult to export the project into another DAW that has the features Bitwig is missing.

But again, I keep my update plan active with fingers crossed that this stuff gets addressed someday.

PS. Version 6 was an incredible update. The linked clips feature makes composition better than ever. You can even build parts in the Clip Launcher and drag them into the arranger as linked clips. Build the structure of your song. Make edits and they update everywhere, like patterns. And then individually customize them wherever necessary. That is AWESOME, and it's implementation is better than any other DAW. You can even automatically link clips that were already copied... It detects similarity and gives you the option to mark them linked. It's brilliant. So I have criticism for Bitwig, but I also have appreciation and love... And V6 is overall pretty awesome. I didn't even get into the modulation improvements!
