ThumbJam 2.5 brings Link and so much more

This is just a huge update for ThumbJam, which was already amazing and is now better than ever!

New Features:

  • Added Ableton Link support, along with time stretchable loops, so tempo can be changed at any time now
  • Added new arpeggiator feature, with multiple patterns and options. Playable on screen or via MIDI input.
  • Support for Audiobus Remote triggers, and updated Audiobus SDK
  • Now optimized for iPhone 6/6+ and iPad Pro, with slide-over and split view support on recent iPads
  • Added 3D Touch support on iPhone 6S/6S+ options for velocity, volume, and filter cutoff controls
  • Added static MIDI CC input bindings for many controls (see users guide in app for details)
  • Added touch velocity UI control separate from volume, useful for velocity layered patches
  • Added max pan width control and added random pan control option
  • Relocated split popup button for iPhone
  • Can now send midi volume for x-axis volume mode
  • Make x-axis velocity use more of the space, no more half width. (Can revert to old way in options)
  • Added support for importing Scala or SXML files inside a ZIP archive
  • Now changing presets from the main menu will override any multi-splits (preventing confusion). Changing instruments within a specific split can still be done from the splits panel.
