Is it normal that there's a 0.5 sec delay latency when you press play (both spacebar or screen button) after loading a SEQ file, with only 1 MIDI and 5 audio tracks ? This from any bar on the scenario, not only the intro ...
I have no such problems with BIAB 713, and the 'same' MGU file ...
Doesn't happen here, but I don't use mgu files in RB, I always save as a seq file right away. I'll see if I can find one to test with. I do notice your ASIO is running at 2.9 ms .. pretty small buffer. Mine is usually 5.8 ms
Found mgu sample files .. still can't replicate the issue

Hi Rharv, you mean pre load track buffer? mine is 2000 ms. The other 2.9 is from my RME UFX, and has no problems with BIAB or any other audio nor video software ... Also it seems non-changeable; RME is famous for their trickery LoL.
Yeah, I see all that from your picture. I just can't say I see the half second delay when clicking play.
As a test, play the file and mute/unmute a track. Does it have the same delay? Even this seems instantaneous here, but thought it might be something you could check that may give more clues. How about slider movements, do they have a delay? Have you tried the old 'turn it off and turn it back on' for the machine?
I do not work here, but the benefits are still awesome Make your sound your own!
Muting etc, all the same. Slider OK. My PC is tuned to the hilt, Windows 10 LTSB without all that MS c-o-c-k & Bull. Sonnet USB card with four controllers, one for Audio only. It has to do with RB IMO. Some setting maybe. I'll look into it later. as i decided to continue the RB project once again in Cubase instead.
ADDED: Tested Realband 2019 v5 and 2020 v1 ...same thing.
Are you aware RealBand or PowerTracks Pro does not start playback until all tracks are completely built while Band-in-a-Box builds a few bars of each track, begins playback and continues to build tracks as a background task until all tracks are built?
This difference in the way each program builds tracks make it appear that Band-in-a-Box builds tracks much quicker than RealBand or PowerTracks Pro.
Is it possible the how programs build tracks difference is what you are experiencing?
Nope, always, tracks generated, SEQ loaded, and BIAB works OK. As said above, it must be some Realband setting, and it's just with play. Yesterday i tried RB 2019 v5, and 2020 v1; same thing.
What MIDI synth(s) get loaded? Is it possible a synth or MIDI driver is causing this? Maybe something weird like RB is suddenly using MIDI mapper or something .. just off the top of my head. Not likely, but I can't think of much else looking at your specs and your post/image.
I do not work here, but the benefits are still awesome Make your sound your own!
Without, with Coyote wavetable and Halion Sonic SE no differences. No Midi mappers ... Maybe something to do with Midiclock etc, you made me think LoL.
ADDED: been experimenting with various settings ... same delay. Reset factory defaults. NADA.
Note: BIAB and all other video or audio runs fine, no irritant playback start delays.

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!
