GSequencer 0.8.x goals

Advanced Gtk+ Sequencer 0.8.0 has just been released. There is not intended to do much during this minor release. Except the considered essential built-in ags-envelope recall.

So there is much time to extend the existing unit tests. And for sure the missing functional test of AgsAutomationWindow.

Advanced Gtk+ Sequencer v0.8.0 - release notes

General improvements to AgsMidiBuilder has been done during this release. As well extended the user interface to do:

  • implemented export to Standard MIDI File
  • implemented import of Standard MIDI File


Performance issues has been detected related to CPU expensive GUI thread poll. Now, a call to nanosleep() has been added resulting in less CPU consumption. Further the AgsMidiin object doesn't create anymore a poll thread. Due to CPU usage costs it has been removed.

I'm able to do MIDI playback with my 6 year old Macbook Pro. However MIDI support is not perfect, yet.

Envelope and the notation editor

Unsure how to implement but you should be able to adjust envelope per note. The idea is to add an additional panel or dialog that let's you adjust the ags-envelope recall. This recall is able to apply envelope per AgsNote.

Since AgsNote has got envelope information it should be possible.
