• We now make sure that a block cannot be dragged outside the main window
• Added ability to separately control where to look for VST3 plugins

Fixes

New plugin

• Eight track audio file player – capable of loading/ playing up to 8 audio files either one at a time or simultaneously. Supports AIF, WAV and MP3 formats. Suitable as both a backing track player and for looping short samples, switching seamlessly from one to another while running. Up to eight audio output channels are available.

  (By customer request) MIDI program changes can now be sent out from a MIDI In block using a widget. This allows you to send program changes directly to plugins. Note that using this mechanism prevents Patch Persist from working and can result in stuck notes depending on the plugin implementation. This feature is not recommended for normal use and not officially supported.

Enhancements

• The plugin editors for the Audio Input and Output blocks have an improved UI to better handle interfaces with large number of I/O channels.
• Added ability to start Gig Performer with the argument “-nosave” such that Gig Performer will never ask to save the gig changes on exit. This is intended for users running headless machines.
