So in two measures I want to go from X BPM to Y BPM between every verse ending up much quicker then I started the song. How do I do that over two measures gradually? Thanks everybody.
An extra tip; in RB it is done using the Fill feature (which fills the Tempo Map window with data adjusting from Point A to Point B) .. not sure where this feature is located in BiaB ..
I do not work here, but the benefits are still awesome Make your sound your own!
While you can use F5 to change tempo in BIAB by a specific bpm plus or minus, or indicate a % change, it is implemented measure by measure, not gradually within the measure.

In addition to what Matt mentioned, it's often been requested that BiaB allows gradual change in tempo, rather than at the bar-by-bar coarseness currently offered. This would be especially useful in introducing rallentando at the end of a song.

I know where I want the change to be.... start...in process...and at the new tempo.
Most of the changes happen over no more than 2 bars. Each bar has 4 beats.
SO..... I go in and ADD 2 measures where I want the change. I then go in and change the two measures and the 2 new ones to 2 beats. Song tempo might be 120. So the first measure is 110, the next 100, the next 90, and the final one is 80, or a hold.... depending if I want to stop of keep going. Normally I'm using it to stop so the last one is a hold.
You can speed up by doing it backwards of the process above.
Add to a plug in on an extra midi track you're not using, For example the "Soloist" track.
Set midiOUT to say "01: Internal MIDI"
Turn on the Conductor, "Enable control by Midi keyboard" Set the MIDI in of Band in the Box to "01: Internal MIDI" Yes, the same as Midi out from the soloist track.
Notes you add to Soloist track will control the Conductor.
Add some C4 notes to the soloist track over the measures you want to increase tempo.
Each time a C4 plays the tempo will increase by 1
This a very interesting way to add a "control" track to BAIB. Pick "Show MIDI notes" in the Conductor to see all the options.
This is a really old thread, but has some valuable info. Has anything since this thread been implemented that allows for gradual tempo changes, versus bar-by-bar?

I'm not aware of a gradual tempo change feature. I still believe it is only bar-by-bar.

I could see something like that or Raintalk's solution working for MIDI, but don't think it would work for RealTracks. I assume there's a fair amount of "magic" in the time stretching required for RealTracks to continue to sound good, and don't know that BiaB is wired for that to happen in real time.

I agree changing tempo in MIDI is seamless but I also believe it could be implemented somewhat in RealTracks. They are already designed to stretch using the Elastique Pro algorithm. The trick is not to go too far from the base tempo at which they are recorded, or you start hearing artifacts. Plus or minus 5% is safe. Speeding up by as much as 10% often works fine. I often do this for endings and I use an audio editing program. Styles are different; you just have to try it to see if it works with the style you have.
This is certainly a good item for the Wishlist.

I agree, but I presume RealTrack processing and time compression/expansion is mostly an offline process for rendering, regardless of the perceived speed from a fast machine. Just can't picture the solutions involving controlling the MIDI clock or BPM setting in real time (MIDI sync) would yield good results. But DSP and audio processing isn't my area of expertise. Hope that makes sense.

I realize that, but I don't think it's driven by the BPM counter or MIDI clock that drives realtime playback. Again making assumptions based on experience with realtime graphics rendering and a few other software engineering things, so they could have some special sauce working that I'm not aware of.

I see the MIDI clock as the greater problem here. BIAB does not sync to a time clock. I’ve taken rendered tracks to a studio only to find they are ever so slightly off from the tempo I thought they were.

I always assume rendering and playback are two separate "problem spaces". It doesn't take much processing power to play back and mix 8 tracks of prerendered audio, for example. But playback has to take place in real time regardless of the processors involved, otherwise reality is suspended. I think I've read that BiaB may render RealTracks into memory buffers in chunks, so playback can start before the whole song is rendered. And I think BiaB provides the same audio quality from a rendered RealTrack song regardless of CPU speed. DAWs provide options for freezing virtual instrument tracks so that a slower computer can still play back a high quality result, regardless of whether that computer can drive all the virtual tracks in real time.

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):

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.

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.
