so after all these years, BB still inserts dim7 chords when I -only- write dim, presuming them to be the same. They are NOT, anybody who studied tonal harmony properly knows that. Try this progression, a circle of fifths:
Cm, Fm, Bb, Ab, Ddim, G
all sounds well, IF the Ddim is played as a diminished triad, spelled D,F,Ab. Now play Ddim7 (D,F,Ab,Cb) and hear how ugly the Cb sounds. And yeah, in the case of a dim7 chord here, it's called Cb, not B.
Dim7 chords require proper handling, and they often introduce notes that are outside the key. In this case it sounds bad although all the notes are diatonic. But the Cb makes an augmented second with Ab, which is why it sounds really corny.
And yeah, in jazz no one would probably care. But not everybody cares about playing jazz, either. If you stick that chord in a pop song with the Cb, it will stand out like a pickle in your cornflakes. That is, badly. The right place for a dim7 chords in the key of Cmin is Bdim7. Nowhere else, unless you are modulating.
Triads are triads, seventh chords are seventh chords. They are not always interchangeable.

A few years ago, PG Music added dim chords. There is a setting in Display Options that will enter a diminished triad if you type Xdim. By default, BIAB does interpret dim as the diminished seventh chord unless told otherwise. Without changing the display options, it's possible to access the dim triad by using dim5.
I stopped using dim for dim7 about 25 years ago when the keyboard player in my church band complained. Nowadays, I use dim5 for diminished and dim7 or °7 to end the confusion. Broadway show books still use ° which is fine with me.

As a 'less talented' guitarist, I learned to play Bdim as per the attached - but it has an Ab/G# in it i.e. B, D, F, Ab - what is the true name of that? Is that the dim7? Then a few years after, I found out there was a chord called Bm7b5 (B, D, F, A) (attached) which sounds slightly less confrontational. Andrew

Hi Noel! I see that is under 'Display Options' for the chord window, and wondered if it actually makes a difference to the generated chord or purely for display. I selected the setting in Display Options and input the following chords Bdim Bdim7 Bdim Bdim7 and found that it is purely a display - see attached - the G# is present in each bar. Does anyone know a way of forcing BIAB to omit the 7th? Andrew

These are respectively the diminished (sometimes for clarity fully-diminished) and the half-diminished. The former usually indicated by the 'degrees' symbol, the latter by a similar symbol with a diagonal line through or by the m7b5 form. In the former, the 7 is doubly flattened relative the Maj7, in the latter singly flattened. (e.g. A#->A->G#)
For just the triad, people often write the ordinary 'degrees' symbol, which is OK for the triad, but can be misleading if one is using 7ths in voice leading.

As I read the question, I was thinking this person doesn’t know about the checkbox. Noel revealed that solution. I recall it may have been more than a ‘few’ years ago, but the feature was added at our request.
This thread is another good illustration about how the forum sometimes works. There are two approaches one could take. The first is to lecture us about music theory and point out how BIAB doesn’t do something. The second is to go to the main BIAB forum for Windows or for Mac, and ask if there is a way to fix this problem. We are very likely to have seen it or discussed it before. If it’s a missing feature, we suggest a post in the Wishlist forum. If it’s a bug, we can report it the the developers.

I just tried the same experiment and at first got the same result - no difference - but then I selected a Classical style and it obeyed the difference. What style / genre are you using?

Maybe. I’m not ready to draw any conclusions yet, based on that one very limited experiment. I think there are styles that simply don’t play 7ths. Notes Norton would know better. And there are a bunch of options I’ve written about in Tips and Tricks.
And it might be sunspots - coincidence. Or in my case, a dead short between the chair and the keyboard.

This, along with several other issues, is why I prefer MIDI. One note off, move it. BIAB is a complex piece of software that occasionally requires explanation from long-term users. As mentioned in another thread, standard notation is not always "standard". It is highly likely that questions about almost any issue can be solved through a workaround by the many people here who are familiar with the program.
Many users of this software have acquired other software programs to circumvent some of the issues. A considerable number of things can be done in BIAB. One note, even in an audio track, can be changed in pitch if needed.
The inevitable learning curve for this program will likely be frustrating for many people. Things are considerly better now than when we had to use floppy disk to load the program...lol

Not for everyone, but I use Melodyne Studio to edit RealTracks very similarly to MIDI. I only infrequently even try a track regeneration, because "wrong" chords and reharmonzations are so easily addressed with Melodyne.
I'll agree with any argument that Melodyne shouldn't be necessary. But I can't unscramble that egg for me...

Thanks for the image. It helped a lot. I tried the _DAPPER style. After setting the Display Option to show 'dim' as the diminished triad, I received the same result as you. To me, this suggests that: (a) it's style related as Matt suggested; (b) the performer of the Realtrack 1662 did not play a diminished triad and so the 'dim' chord was mapped by PG Music as dim7; (c) PG Music did not map the dim triad separately.
RT 1662 is from set 147 which was released in 2011. I've checked back through the User Manuals and the diminished triad was introduced mid-year in 2012. This information means that when RT 1662 was recorded, the musician involved (Mike LeDonne) would have only been asked to play diminished seventh chords because in 2011, the diminished triad was not part of BIAB's repertoire of chords. Regarding Realtracks that were created after 2012.5, I'm pretty sure that most (if not all) will contain a diminished triad.
How to fix your issue with dim chords...
There is a setting called "Autofix sour notes". If this is activated for RT 1662, and instructed to fix notes according to the chord symbol, then after the track is generated, BIAB will process the track and tune any notes that are not part of the chord so that they become part of the chord.
The lower image below shows where the Autofix Sour Notes option is found. When I used this option, the diminished triads were corrected.
I agree with Matt. Excellent detective work Noel, and perfectly explained. Thank you for that.

As others have said - fantastic research Noel, and thanks for the solution! I have been aware of the 'sour notes' option but have never used it and didn't think of its application in this situation. There's so much flexibility in BIAB! And thanks to Matt's comment as well - apologies I didn't respond sooner, but being in GMT+9:30, it can sometimes take 36 hours before I see other posts - but in this case, it sounds like my tardiness allowed more informed and inquisitive expertise (Noel) to shine.

I've just acquired Melodyne Studio. A video demonstrating how you use it with real tracks would be a great addition as Melodyne has been offered as a $99 upgrade from time to time. I use it (or will) for harmonising my vocals and fixing pitch etc.

Hate to take us off topic, but I am just about to pull the trigger on my Melodyn Editor to Studio Upgrade. This is a big ticket ($299) upgrade. Sure would love to know where you find this for $99? My 30 day free trial is almost over.
By the way, I have moved thorough all the levels of Melodyn over the years. But at this moment Studio, with its multiptrack editing, has want I need.

One of the worst kept secrets is that some resellers do not require previous version verification with upgrades. It depends on the software. Sweetwater will sell you the upgrade. It's been so long since Celemony has had a major version upgrade but I don't remember entering my old license when redeeming my upgrade codes in the past. I think my first version of Melodyne Editor was v.2.

202 New RealTracks Released with Band-in-a-Box 2026!
With Band-in-a-Box® 2026, we've released 202 incredible new RealTracks (in sets 468-488) in a variety of genres—featuring your most requested styles!
Jazz, Funk & World (Sets 468-475):
Our new jazz, funk & blues RealTracks include a groovin’ collection of RealTracks and RealDrums! These include more requested “soul jazz” RealTracks featuring artists Neil Swainson (bass), Charles Treadway (organ), Brent Mason (guitar), and Wes Little (drums). There are new “smooth jazz” styles (4), which include a RealTracks first: muted trumpet, as well as slick new smooth jazz brushes options for drums. 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. There are also new electric blues RealTracks, including electric blues with PG favorite Johnny Hiland (3) and soulful electric slide guitar from Colin Linden (4). If you love funk & gospel, there are great new options this year, including gospel organ (3) from Charles Treadway, as well as new funk, tango, and rock ’n’ roll drums (3) and bass (1). And for big, bold arrangements, we have uptempo soul horns (4) featuring a three-part hip horn section with options for a full mix or stems of each individual horn — plus an accompanying rhythm section (4) of drums, bass, guitar, and electric piano!
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.
The 2026 49-PAK is loaded with other great new add-ons as well. Learn more about the 2026 49-PAK!
