Joining Thumbjam, Sonosaurus' DrumJam has been updated to support Audiobus! iPhone 5 screens are also now supported in the new version.
What's new in 1.1:
Introducing Audiobus support: Now you can play audio from DrumJam directly into other Audiobus-compatible apps! See http://audiob.us for more information.
- Optimized for iPhone 5 and new iPod touch
- Korg WIST (wireless sync-start) support
- Fixed MIDI sync drift issues
Some DrumJam issues with connecting to Audiobus have been mentioned in the comments for Thumbjam, but Sonosaurus has been quick to respond and are investigating it now. These issues might be isolated to iPad 2s running iOS 6.0.1.
Long-suffering Reaktor users will be impressed with this, if you haven't yet played with the 5.8 update. He just moves his hand and a whole big list of controls gets instantly populated; for easy drag-and-drop assignment. Perhaps even more impressive is that this works in Ableton Live now!
Konkreet Performer is still on sale, so if you use Reaktor you should really consider grabbing this!
