What's New

Version 2.0

This major update of Heavy Brass introduces several new features, most notably:

• Introduces "App States".
• Improved tuning dialog with master tune and factory presets.
• Adds extended features to the virtual on-screen piano keyboard.
• Adds optional MIDI device configuration screen.
• Latency down to 1ms now available.

As well as a number of software corrections, most notably:

• Audio Unit: Addresses audio export ("offline rendering") issue (introduced by iOS 11).¹
• Inter-App Audio / Audiobus: Fixes crash which could happen (with iOS 11) when the app was launched from either Audiobus or as IAA from a third-party DAW app.
• Fixes touch latency of 1s on virtual on-screen piano keyboard (introduced by iOS 11).
• Fixes issue with manual polyphony and latency settings.
• Numerous other minor UI corrections.

Please note that we had to raise the minimum requirement to at least iOS 9.3 due to new software features we use. However the App Store still offers you an older version of Heavy Brass for devices running an older version of iOS.

¹ Requires at least iOS 11.3 and also an update of your DAW app to be resolved. For more details about this issue: https://doc.crudebyte.com/iOS/Technical-Notes/Audio_Unit_Issue_219DE61/

Excellent results...

Hoping for a few more features... would like to control length of swells. Is there a way to do this? Would be great to select which instruments are in combos.

Getting pro sounding results already, tho...



On my iPad 2 the program only runs for a minute then crashes. Can you make one for the iPhone I have a 5s. I can't use this great program and I wanted my money on it!

Developer Response

Please note that the iPad 2 model is not supported by this app. Like the App Store description says: minimum requirement for this app is at least iPad 3 / iPad Air 1 / iPad mini 2. Of course you can request a refund for your purchase.

Good and bad


Good sound, bad interface. Worth $5 though.
