Trombone Champ News

v1.12 is now live, with smoother track scrolling!

Great news! Trombone Champ now uses different math to scroll the tracks during gameplay, which should lead to significantly smoother movement for most users. Apologies for not doing this sooner... This is really something we should have explored further before launching the game 35 years ago...

Previously, the game would read the "timestamp" of the song every single frame and move the track accordingly. In theory, this should work perfectly, but in practice it sometimes lead to jerky movement, most likely due to the game's framerate not perfectly syncing up with the elapsed time of the audio.

Now, the game moves the track at a smooth, constant rate, based on elapsed time since the last frame (delta time). Additionally, to make sure the track doesn't gradually de-sync for any reason, the game checks the audio timestamp each measure and re-syncs the track if it's more than 4 pixels off. In our experience, this smooth scrolling is much more precise than anticipated. It works really well and almost never needs to re-sync at all!

On the primary PC where we develop and test the game, scrolling feels significantly smoother. It's a very noticeable difference!

However, on the Macbook Pro we use for Mac testing, the game already scrolled extremely smoothly. We're not really sure why this is the case, but you may not notice a big difference if you're playing on a newer Mac laptop at 120fps. If you're playing on an older Mac at 60fps, you will probably feel the difference.

Please note: This new smooth scrolling is now the default. If, for some reason, you prefer the old scrolling, you can select it in the Settings menu, under "Gameplay."



Smooth scrolling is the biggest improvement in this update, but there's additional stuff:
  • You can now disable the song previews that play in the Track Select screen by using the option in Settings if they annoy you for some reason.
  • Visual appearance of settings has been cleaned up.
  • Chosen character, trombone, and sound pack is now more visible in Character Select.
  • Sound effects when unpausing are dramatically improved.
  • Restarting a track is slightly faster.
  • Control Testing Zone easier to find, looks slightly better, and displays current control choices.
  • When paused, the player model no longer rotates in the background.
  • Various code adjustments to catch potential bugs with custom tracks.
  • BUGFIX: If your master volume is below 100, the game should no longer get quieter during gameplay / music sequences.


We hope this new scrolling makes the game more enjoyable for everyone! It really does change the feel of gameplay.

Stay tuned for more updates, and thank you for your patience!

Mods & Game Updates

Hello! Often, when we release Trombone Champ updates that add new functionality, we receive a bunch of technical support emails about the game not loading songs, displaying a black screen, etc. 99% of the time, these issues are caused by having old versions of mods that need to be updated.

Thankfully, we've been working closely with the modding community to make sure that mod updates are available when Trombone Champ updates go live. And recently, modders have started recommending user-friendly mod managers, which make it much easier to install mods and receive critical updates for them.

We sometimes say "update your mods" when we push updates, but thought it might be a good idea to talk about mods in more detail!


[h3]Mods & Trombone Champ Compatibility[/h3]

Let's start with the basics: talking about how Trombone Champ's mods work. In short, they work by injecting code into the game's scripts, and sometimes replacing blocks of code in the game's scripts. Generally, the oldest mods for Trombone Champ would replace very large chunks of the game's code, while newer mods replace less code. Because of this, newer mods are less likely to cause game-breaking issues than older mods.

Because of how Trombone Champ mods work, any change to the base game - even very, very small ones - can result in the game locking up or crashing if mods are running.

On the dev side, we do all we can to prevent this from happening: to give a specific example, we've adjusted where we sometimes add new code in the Gameplay scene in order to lessen mod conflicts. Code that we would have normally added to one function might get dropped into another, if we know that the first function is heavily modified by mods.

Even with these precautions, any new elements or functionality—for example, in the newest update, the little "Max" star that now appears next to your combo multiplier when you reach 10x, the timer that appears when you unpause the game, etc—can sometimes require mods to be updated. It doesn't matter how small the change is: even a single new line of code can cause the game to lock up if, by chance, a mod references or changes the block of code where that line appears.

"Well," you may ask, "why didn't you include some sort of mod browser in the base game, that would allow the base game to support mods in a way that doesn't affect the standard code?" If we had any idea the game would be actually become popular, we would have! The game's success took us by surprise, to say the least... and by the time we started to think seriously about stuff like building out a level editor and allowing users to create and load custom tracks, the amazing community surrounding the game had already created thousands of tracks with technical capabilities far beyond what we'd ever imagined...


[h3]Working with the Modding Community[/h3]

For quite a while, we've been working closely with the modding community: we try our best to share Trombone Champ updates with mod makers a week or more in advance, so the modders can test the game's updates and see if any changes in the base game require their mods to be updated.

Because of this, modders usually have mod updates ready as soon as the updates go live. For example, when we updated the game from v1.10 to v1.11, modders knew exactly when we would push the update to Steam (3:00pm EST) and had their mod updates ready minutes later! Amazing!

However, having mod updates available is only one piece of the puzzle; users need to actually get the updated mods! Luckily, the mod users now have a nice solution in the form of mod managers.


[h3]Using Mod Managers[/h3]

It's a pain having to update mods by hand, so most of the modding community highly recommends using a third party mod manager application to download, use, and update mods. There are lots of benefits to using a mod manager application rather than installing them manually:

  • Mod updates get pushed automatically, so you should never need to worry about mods breaking when the game gets updated.
  • You can easily see which mods are installed, which are available, and add/remove them with just a click.
  • It's safer: you don't need to worry about breaking the game by installing mods wrong, or downloading malicious content by accident.
To get started using a mod manager, we generally recommend following the instructions provided by the modding community. You can find an in-depth guide at trombone.wiki. Please note that these third party tools, custom maps, and the documentation surrounding them, are all created and managed by the community.

If you have any questions surrounding modding, there's an active Trombone Champ Modding Discord server, which you can find here. Again, please note that this is completely community-created and managed.

We've made a lot of changes to Trombone Champ since launch, and we plan to make a lot more. Some of the updates we'd like to eventually make will introduce much bigger changes to the Track Select screen, Gameplay screen, and more. So, the sooner you move your mods over to some sort of mod manager that makes them easier to update, the easier things will be in the future as the game continues to evolve!


[h3]Running Previous Versions of the Game[/h3]

If you have some custom mods that you absolutely need for some reason, and these mods break the game after an update, you can also choose to use an older version of Trombone Champ. This is not recommended unless absolutely necessary, as you'll miss out on the quality of life features, newest tracks, and bugfixes we're constantly patching into the game.

However, should the need arise: you can right click Trombone Champ in Steam, choose Properties, click Betas, and then choose the "previous_version" option in the dropdown. After clicking OK, Steam will redownload the previous version of the game. We generally update the previous_version branch after every large, significant update.

Make sure to check in on whatever issues you're having and opt back into the main branch as soon as fixes are available!


[h3]Deleting Old Mods[/h3]

If you have old mods installed, and want to move to using a mod manager, we recommend making sure you've deleted old versions of mods first.

Please note that, if you want to delete mods, uninstalling and reinstalling Trombone Champ through Steam probably won't do the trick. This is because Steam only manages files that are shipped with the base game, and doesn't touch files that have been added to a game's install folder. So, if you uninstall a game through Steam, all of the old mod files will probably still remain in the install folder.

If you want to completely clean an old Trombone Champ install, we recommend right clicking the game in Steam, clicking "Properties," and clicking "Browse Local Files" to see the folder where the game is installed. Uninstall the game through Steam, and then check the folder to see if anything is left over. You should be able to safely delete any files and/or subfolders left in the install folder. If you have a lot of custom tracks that you'd like to keep, make sure to copy those out of the Trombone Champ install folder before deleting everything!

Also, please note that your save files and settings are kept in a separate folder, so you don't need to worry about losing your progress when you uninstall the game or delete stuff in the install folder.


[h3]In Conclusion[/h3]

Thanks for supporting Trombone Champ and reading this whole post! Wow, this was a long one! In summary:

  • If you installed mods in the past and your game is busted, you almost definitely need to update your mods
  • If you're not using a mod manager, we recommend trying one out, as it will make things easier as the game continues to be updated.
  • We try our best to update the game in a method that doesn't break critical mods, but large updates will probably break some mods anyways.

We'd also like to thank the modding community for their amazing work. We never expected the game to have such a robust modding scene, and it's been amazing seeing the stuff everyone's been creating!

Happy tooting!

Update v1.11 is live!

Update v1.11 just went live, which adds a lot of features that probably should have been in the game since launch!

This update adds some new elements to the gameplay scene, so if you're using very old mods, you will probably need to update those. Or, you can right-click Trombone Champ in Steam, click "Betas," and choose the "previous_version" branch, which will opt you into an older version of Trombone Champ.

Here's a rundown of what's new, with context:
  • Two new tracks: "Washington Post March" and "When the Saints Go Marching In!" "When the Saints Go Marching In" is the first track to have a dedicated solo improvisation section. Future tracks may include these as well! You can play whatever you want during those sections and it will not affect your score.

  • You can now pause and unpause during gameplay. Please note that, if you're playing a custom track with a complex background, unpausing may break or de-sync them until those mods get updated.

  • Tracks now play previews in the "Track Select" screen. This will likely only work with tracks from the base game for the moment, as each track has a custom sound file.

    This should have been in the game since launch, but it was slightly trickier than it seems. We couldn't simply play the backing track, since that usually doesn't feature the melody... for example: "Taps" would just be total silence. Additionally, if we loaded the backing tracks as you scrolled, that potentially lead to lots and lots of loading, especially if you scroll quickly down the list.

  • Note statuses ("Perfecto," "Nice," "OK," etc) are more attractive + informative during gameplay. When you reach 10x, you now see a little "Max" star, rather than having the word "Max" in giant ugly text. Additionally, the game now tells you when you miss a "gap" between notes. Previously, missing a gap would cause you to lose your combo, but the game didn't communicate this in any way. Functionally, nothing should have changed, except you can now see the status.

  • You can now "engoldenate" cards after beating the game. If you have ten copies of a card, you can convert the card into a golden card. We have more plans for this in the future, but for the moment it gives seasoned players another goal to work towards...

  • Trombone Champ now saves your character, trombone, vibe, and soundpack choices. Additionally, if you mute the menu music using the button in the corner, that should be saved as well.

  • The volume faders in Settings screen now work more naturally. Previously, audio would be effectively muted at the halfway point - now when the sliders are at 50%, the sound should be at roughly 50%. Please note that the game may initially sound louder or quieter than you're used to when you launch this update!

  • Various buttons now have more visible selected states.

  • The title screen looks better, and the sound effect that plays when exiting the title screen is less grating.

  • Fixed an issue where hovering over cards could cause small visual problems in "fast buy" mode.

  • The card graphics have been optimized and the scene may load faster.

  • In the card scene, you can now cancel when turding multiple duplicates.


Overall, pausing and the track previews are the most obvious changes here, but we're happy to see the game gradually feel more & more polished.

On another note: these new tracks apparently bring the base game's track total to 48. When the game launched, we had around 25, so this is a pretty significant jump We have a great idea of something special to do for track #50!

We have a lot more stuff planned - we're working on more updates, fixes, and some secret stuff we're excited to announce later this year. Thank you for your continued patience!

Trombone Champ gets truly nasty, adds the hellish Flight of the Bumblebee




Trombone Champ, the fast-paced rhythm music game filled with nasty toots, just got even nastier by adding Flight of the Bumblebee to its roster of hits. That means as of today's update 2022's best comedy game is even funnier, because the famously difficult piece of music is absolute hell to play on a mouse-controlled trombone...
