I want to make tempo changes where the whole recording gradually slows down or speeds up (rallentando, accelerando etc...) mostly as an ending but sometimes in the middle of a song before returning to the original tempo (a tempo).
Is this possible? I know I can change the tempo bar by bar in bar settings but can it be done as a gradual continuous change?
You can introduce Rall. but not little-by-little, instead, only one bar at a time.
As you are aware, proper Rallentando provides a gradual decrease in speed.
BiaB changes the tempo at each bar. Rallentando has been requested many times.
Press function key F5 at the required bar and set the required value:

The % Change in BIAB is normally enough for me, but when it isn't, I do the editing in a DAW or sound editor program that supports pitch and time shifts.

Hi, slowing down using F5 and a negative % works but I found on playback in BIAB it sometimes stops for short periods in playback. It is fine once rendered. I also found it a bit complicated but ok once used to it.
At the risk of sounding like an advertising guy my preferred method is to pull the files into Reaper. Set the playrate option to change playrate whilst holding key then add an automation lane to alter playrate. Then simply drag the rate and slope shape to what you want. Very simple and extremely efficient.

If one wanted a smoother slowing down in 4/4 time, it would be possible to create 2/4 bars in place of the 4/4 bars (nothing else needs to change) and then use bar settings across the bars.

Depending on the style the 2/4 measures can be a problem by starting the style at the beginning of the measure every 2 beats. I find it works OK in some styles but not others.
The best solution to me is exporting to a DAW and using the rit or rall function there.
IMO BiaB is an excellent auto-accompaniment app, the absolute best available. However exporting the BiaB project into a DAW can take the very good results from BiaB and make them even better.
Power Tracks Pro Audio, Cakewalk/Sonar, Cubase and so on can help enhance your project.
I think every computer musician should have 3 apps, BiaB, a DAW, and a full-fledged notation program.

Insights and incites by Notes
I agree 100%.
Life is short so make sure you spend as much time as possible on the Internet arguing with strangers.
64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
When I come up to the ending, I will generally do a slow down to a hold in 2 measures. I add a few measures. And make them all 2 beat measures. I found that if I try to slow down on a 4 beat measure, the speed drop is noticeable in that it's abrupt and not smooth. So if the song is at 120bpm, the first 2 beat measure drops to 110, then the next 2 beat drops to 100 followed by drops to 88 then 75... and finally a hold with fade to silence.
The drops can be non-linear as a slow down tends to increase in slowness.... This tends to give me a very smooth deceleration.
This is just one song where I have used this very method to slow the song to a hold ending
edit: remember that when you edit the bar settings, everything that follows will have the same new settings. So, you will need to add or use following measures to pick back up and go back to a 4 beat bar....
Also..... I ALWAYS compose my songs in Band In A Box ( BB for short ). That's where I set the tempo, key, formulate the intro, structure of verses, choruses, and all the other goodies. I do my slow downs in there too. Then..... I save and close the project in BB and reopen it in Real Band (RB). RB gives me all the tracks rendered to audio. AND.... I can add other instrument real tracks that may not be in the original BB style. Such as steel guitar in the LA Hard Rock style. I then export my audio tracks to Sonar which is my DAW of choice and continue to add vocal and live instrument tracks and do the mixing. All of the RB tracks will follow the template you build in BB including the pauses and slow downs.
Hope this is helpful.

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.

Blues lovers will be thrilled—there are more “classic acoustic blues” styles, including guitar (5), bass (4), and drums (10) with blues master Colin Linden, featuring understated and tasty background acoustic soloing, plus brushes drums and acoustic bass.

Rock & Pop (Sets 476–482):
Our new rock & pop RealTracks bring a powerful mix of requested favorites, fresh genres, and modern chart-inspired styles! We have more of our popular “Producer Layered Acoustic Guitars (15)” featuring Band-in-a-Box favorite Brent Mason. 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. And we’ve added lots of new modern pop styles (16) — the kinds of sounds you’re hearing on the radio today, featuring exciting new drums, synths, and cutting-edge RealTracks arrangements.
Country, & Americana (Sets 483–488):
Our new country & Americana RealTracks deliver a rich collection of acoustic, electric, and roots-inspired styles! We have new country pop (9) with legendary guitarist Brent Mason. There is also a potpourri (14) of bouzouki, guitars, banjo, and more, perfect for adding texture and character to contemporary acoustic arrangements. We’ve added funky country guitar (5) with PG favorite Brent Mason, along with classic pedal steel styles (5) featuring steel great Doug Jernigan. 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.
And, if you are looking for more, the 2026 49-PAK (for $49) includes an impressive collection of 20 bonus RealTracks, featuring exciting and inspiring additions to add to your RealTracks library. 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! There are also new indie-folk styles with guitar, bass, 6-string bass used as a high-chording instrument, acoustic guitar, and banjo. Plus, dedicated "cymbal fills" RealDrums provide an added layer that work very well with low-key folky styles with other percussion.
