MultitrackStudio for iPad 2.1 arrives

Here's what's new in MultitrackStudio for iPad 2.1:

• Now includes 64 bits version (better performance).
• On 64 bits iPads the Guitar Amp effect uses 4x oversampling instead of 2x (better sound).
• Semi-transparent 'Rewind' / 'To last start' hints appear on touching transport counter box.
• Onscreen MIDI keyboard is a bit smaller (except for Guitar and Drums layouts).
• Height of full-size tracks is now automatically adjusted when MIDI keyboard appears or hides again.
• Audiobus now works with 32 bits values instead of 16 bits.
• Uses Audiobus 2.1.6 SDK.
• Some graphics and user interface improvements.
• Punch-in recording: transport now automatically starts at least one bar before punch-in point (2 seconds if editor timescale isn't set to bars).
• Improved MIDI recording compatibility (recording MIDI data from certain apps didn't work).
• Fixed: error message could appear after purchasing Pro Extension.
• Fixed: issue with sending volume controllers (#7) to External MIDI Instruments
