Every time I try the ACW I seem to get a problem. it's operation really needs to be simplified.
Here's what I suggest. ... user presses a button that says I want to add tracks to an imported song In my case songs I've done in commercial Studios. .... ACW then analyzes the song.. and then does its thing .... after analysis the user then can add real tracks which sync up to the imported old song. .... optionally the ACW will split the old song into stems for remixing
Sorry but I just spent too many hours trying to do this ie using realtrax syncd up to an old imported song. Which I'm sure a lot of people would like to do

BIAB & RB2026 Win.(Audiophile), Windows 10 Pro & Windows 11, Cakewalk Bandlab, Izotope Prod.Bundle, Roland RD-1000, Synthogy Ivory, Session Keys Grand S & Electric R, Kontakt, Focusrite 18i20, KetronSD2, NS40M, Pioneer Active Monitors.
No. JAOM suggests four elements to process. BIAB does all four without any bugs, missing components, or steps to sync imported audio with BIAB generated tracks. Posted in the BIAB for Windows rather than the Wishlist thread, these suggestions seem to be more from frustration, which is certainly reasonable, with OM spending hours without success.
There's nothing needing simplification in the Stem Splitter process. The process was updated in 2026 and now has little popup explanations throughout. It is a straightforward process.
Looking specifically to what OM was attempting; songs he's done in commercial Studios and splitting them out to stems and syncing them to RealTracks, I think he may have better and faster success doing this in RealBand. RB has an easy and manual click track feature that should work on his commercially created songs, recorded with or without a click track. It's simpler and more intuitive than using the BIAB ACW. The RB ACW may be more familiar and simple than the BIAB ACW if he decides it's necessary to use it. RB has the same stem splitter program and all of BIAB's RealTracks are accessible.
It would also be helpful to him and the forum in general, to post the how, why and what processes and techniques he spent hours on so many eyes can analyze and help streamline the process in a discussion in this thread.
I find the ACW won't even generate an accurate chord sheet. Whereas other software does with some minor changes. Try importing a song with chords in open special and you'll see what I mean.
If I'm confused I'm sure new users are very very confused. I think what is desperately needed is for PG to produce a detailed video showing how to add new tracks to Old Masters That are imported.
In summary the whole shebang needs simplifying. NoteI i have no complaints about the stem split functions great stuff.
I would like to suggest some additions to the stem splitter dialogue identifying the file to be split Maybe additional buttons for creation of chord sheet and also equalize tempo.
I won't even get into in the ACW setting bar lines I've wasted more than a few hours on that.
Maybe I'm just dumb lol.

I can't comment on if you are dumb or not, but, I certainly agree with you that "... we have a problem". Unfortuantely, there is nothing new in what you are reporting. It has been raised to the highest levels, but few are willing to accept that fact.
Soooo is there software out there that will Allow updating of Old Masters with new tracks synchronized.
I tried again today and bb would not even create the chords from imported audio propaplly ...sigh. Other software will however. It's all too convoluted and complex..

Dan. Soooo is there software out there that will Allow updating of Old Masters with new tracks synchronized. Om
...that word "synchronized" is key!
Yes! Start with SMP - it will identify all the chords in your "old master". Along with the key, timing and tempo. It will create a Tempo map which will come in handy when you want to insert midi tracks. It will then separate out the individual instruments as audio tracks (stems). It will create midi block chords as a separate track. Afer you have all this content, copy and paste it all to your DAW. That was the easy part. Once you are in your DAW now the fun begins - production and mixing.
It looks like Dan has got you sorted with software that will accomplish what you want to do with your old master files. That's a good solution.
< Try importing a song with chords in open special and you'll see what I mean.> I did take time to do this and found nothing surprising. I was able to replicate your project and used the Open Special with an original song I recorded in a commercial studio in 1975 with a live band and recorded without a click track.
From the time I opened BIAB, imported the file, ran the ACW, analyzed the Chords, used the ACW to create a tempo map, Found a suitable Style and everything was complete and accurately synced in just a bit over six minutes. That's not a reflection of my skill but is a clear indication there's no issues with the ACW working correctly.
I've attached a screenshot showing how just ensuring the first four bars were precisely aligned and placed manually, allowed the ACW to set fairly accurate bar lines for the remainder of the song using the Auto Marking button and only a few adjustments throughout the remainder were necessary to create a good tempo map.
< "I find the ACW won't even generate an accurate chord sheet." coupled with "I won't even get into in the ACW setting bar lines I've wasted more than a few hours on that." > Accurate chord detection and analysis results depend very much on precise and correctly setting the bar lines.
Hopefully Dan's suggestions will get you quick results with your project.
Unfortunately I don't have time to look at these problems further due to upcoming medical appointments.
I really think someone or PG needs to do video on YouTube showing step by step how to do this.. ie adding PG content to an existing master recorded in a studio. What is smp ??
the very best to both of you

This tutorial will give you all the basic information for analyzing and chord detection any audio file. This will work with your master files just fine. It's separate from breaking your song into stems but it's an important step to become proficient in the total process. Note how he precisely and accurately adjusts and sets the first few bars of the song before selecting the auto marking. His method is an important step to making the process simple and faster.
.... perspective from a novice ... occasional BIAB user. Every year .... the new BIAB is here, with 200 plus realtacks or styles. Well whoop - tee - doo. .... and give the “more styles and realtracks " a break.
well, back to the ACW topic... I would Ike to see an updated ACW video overview/tutorial incorporating the latest upgrades and GUI improvements...
btw, every year, I look forward to all the new "realtracks" and "styles"... Thanks PGM ♫
ACW has been out for eight years. IMHO, it hasn't seen much improvement. Like all good software demos, they pick a song that works good with its current capability.
I did a deep dive on it this year, again just like I do every year, to see if it's improved. It essentially does two functions so we probably should talk at that level.
1) Tempo Mapping: - In the demo they just drop in a song and get a simple dialog and it drops it in per the physical size of the file. This is actually the best approach. You can also do it via the import process and it starts you up with a more complex window asking for locations in beats etc. That just tends to confuse people. - In the end you identify beat one and that starts the clock.
- The first problem I ran into was it assumes that you have downbeats on every bar. This may not be the case as the first song I was testing had chords that played for two bars. This throws the tempo mapping off from then on it gets a lttle awkward to try to fix it. - It does try to calculate a constant beat based on your first 2 to 3 manually marked downbeats. It appears to do this with pure math looking for an average. Often this results in all the automatic down beats being slightly off and the majority of them have to be manually set. (As a side note Z Plane the software it's using to detect tempo has the ability to analyze every transient pattern and do a more accurate tempo map automatically) PGM should adopt that new technology. - It also assumes that you're using the workflow of the demo: Tempo, Chords, Style. If you're already have a song laid out with a style and chords trying to bring in other tracks (like vocals) and get them to sync is nearly impossible and not recommended for the light hearted.
2) Chord Recognition: - Chord recognition is 100% dependent on how accurate your downbeats are. - For basic cowboy chords it does a decent job. When the product originally came out eight years ago there was two flavors of it and one of them had more control over the kind of chords it should be looking for and some basic rhythms of the chords. There is an area called settings I think But as buggy as it resets every time you open it up and doesn't seem to make much of a difference. This is another area of improvement.
It is usable with a lot of trial and error and a lot of patience, but in my opinion the whole workflow and accuracy needs to be improved since it's been around for eight years and the Z plane libraries have gotten better.
Studio One (latest version), Win 11 23H2 , i9 -10940X 3.3 GHz, 32GB Mem, a 4K 40" monitor, PreSonus Studio Live III Console as interface/controller. secondarily test on Reaper, Cakewalk, and S1 on Surface Pro 3 Win 10 (latest versions).
Jeff, thanks for this information... seems to me that PGM and their users would greatly benefit from more attention paid to this potentially very profitable feature...
It's a slow and frustrating process but it's not A.I. and, given that tempo and feel change often in most recording that aren't locked to a click or MIDI etc it's an acceptably tedious process. I use it when I have to - stuff from the 80s mostly when I had a drum machine with wandering speed/tempo - I've had success with it but had to "do the work". Chord recognition - well it depends on the clarity and accuracy of the chords played. Sometimes just using a split bass track is a good starting point for me.

I agree with Ray I find it all a very tedious process.

I don't know if this will help or just add more noise to the discussion.
I had a hard time figuring out how to effectively use ACW. Eventually I got to this point.
1. Be sure the project is set to 120 BPM regardless of the tempo of the song. 2. add your lines manually and use the equalize tempo assuming you know the actual tempo of the original song... or just guess.
Once I started with those 2 things, everything else kinda fell right into place. It's not very common now that I get myself painted into the proverbial corner and have to start over.
You can find my music at: www.herbhartley.com Add nothing that adds nothing to the music. You can make excuses or you can make progress but not both.
The magic you are looking for is in the work you are avoiding.
"Om": I would like to try an experiment with the ACW to try to become more proficient with it. I've watched the PG Music instruction videos over the years, but have not taken the time to dig into making it work. I've also seen user feedback about it. "Om" - do you have an example MP3/WAV file that I could use as a starting point, to see how far I make it? If so, I'll give it a try and post my results to the forum.
Just a thought...

OM has indicated he would be out of touch for a couple days. I am sure he will offer up a file when he is back. But keep in mind he has a OMT (old master tape) he needs help with. Don't ask me how I know. Fact is I made the bold claim that this file could not be treated as needed in BIAB with the ACW. Again, don't ask me how I know. I hope he gets back soon so he can take you up on your generous offer. I have no objections to being proven wrong - it would not be the first time. There was one prior time back in the 90s.

We’ve continued our much-requested disco styles (10), and added new Celtic guitar (5) with a more basic, accessible approach than our previous Drop-D or DADGAD offerings. There are also highly requested yacht rock styles (17), inspired by the smooth, polished soft-rock sound of the late ’70s and early ’80s — laid-back grooves, silky electric pianos, warm textures, elegant harmonic movement, and pristine production aesthetics. Fans of heavier styles will love our new glam metal (13), capturing the flashy, high-energy sound of ’80s arena-ready guitar rock. We also have a set of rootsy modern-folk rock (18), with a warm, organic sound combining contemporary folk textures and driving acoustic strumming.

There are more country songwriter styles (8) that provide intimate, rootsy foundations for storytelling and modern Americana writing. Finally, we have “background soloing” acoustic guitar (12) with Brent Mason — simpler, but still very tasty acoustic lines designed to sit beautifully behind vocals or act as a subtle standalone solo part.

You'll get new country-rhythm guitar styles from PG Music favorites Johnny Hiland and Brent Mason, along with modern-pop grooves that capture today’s radio-ready sound!
