Renoise has been updated to v1.5.2.

Changes:

• Changed MIDI Program Change behaviour: When modifying parameters of a MIDI instrument, Renoise will no longer resend program changes to all the other MIDI instruments, but only to the altered one.
• OS X: Improved VST window handling: VST editor windows should now require less CPU.
• Various drawing / resize incompatibilities were fixed.

Fixes:

• Windows: Fixed possible random crashes when deleting a VST or native DSP device by clicking on the small "X" button in the DSP device.
• OS X: Fixed start-up problems, if Renoise was installed on a case sensitive file system.
• OS X: Fixed broken Apple menu in OSX 10.4.3 and higher.
• Fixed wrong import of 32 bit float AIFC and 24 bit files.
• Fixed broken Impulse Tracker import - songs with compressed samples should load correctly now.
• Fixed initialization problems with the Korg-M1 VSTi.
• Fixed distorted Audio output with the Nomad Phaser VST.
• Fixed incorrectly bypassed *VSTiAutomationDevices: Parameter changes were sent to the VSTi even when the device was Bypassed.
