This appears as an place where the new Playable RealTracks/RealDrums is ideally suited for. I've never used the RealDrums Playable Tracks but it's a straightforward process and as a transition, should fit unnoticeable in the mix. I do work with Playable RealTracks quite a bit and I think the concept is a powerful tool.

Because of the Midi component and ease of editing Midi, you may be able to locate a nice transition and copy it from an existing Midi file song and avoid having to do very much editing.

Here's what BIAB Chat says about Playable RealDrums:

"## Playable RealDrums in Band-in-a-Box 2026
**Yes—Band-in-a-Box 2026 includes “Playable” content that applies to RealDrums parts via Playable RealTracks Hi‑Q sounds.** In **Chapter 3**, Band-in-a-Box 2026 includes **Playable RealTracks Set 5**, described as “over 50 new ‘Playable RealTracks’ Hi‑Q sounds… which match many of our RealTracks so you can easily switch from **RealTracks and RealDrums parts to MIDI notes** while maintaining the instrument sound.”

In practice, this means you can take parts that would normally be audio-based (including RealDrums parts) and convert/perform them as **MIDI notes** while keeping a matching, realistic sound.

## Related 2026 drum feature (separate from “Playable”)
Also in **Chapter 3**, 2026 includes **two new “RealDrums Stems” sets**, which “allow you to access the individual wave files from each different mic used to record many of our RealDrums.” This is about deeper audio access/mixing control, not MIDI-playability."
