Radium

Another quick release due to more sequencer audio file bugs. I think the worst is over now, hopefully.

However, this release also contains track headers in the sequencer with name, volume sliders, and mute/solo buttons:


Changes 5.6.2 -> 5.6.3:

• Sequencer: Track headers with name, volume sliders, and mute/solo buttons.
• Sequencer: Buttons to add, remove, and append seqtrack. Faster than using the popup menu.
• Instruments: Let default instrument colors be more colorful.
• Sequencer: Fix various bugs when playing samples.
• Sequencer: Avoid assertion hit about not finding sample.
• Sequencer: Fix some minor paint bugs.
• Sequencer: Improve general rendering performance.
• Sequencer: Draw sample waveforms using less points. Looks better and uses less CPU.
• Scheduler: Trying to track down rare assertion reports when a VST plugin sends out midi signals.

Another emergency release related to playing audio files in the sequencer + fix for the instrument list.

Changes 5.6.3 -> 5.6.4:

• Sequencer: Avoid silent audio when playing an audio file that has fade-out, but no fade-in or envelope, the second time the audio file is played.
• Sequencer: When starting to play audio file, avoid starting to smoothly gliding between the volume it was set to last time the file was played to the volume it is supposed to play. (This smoothing transition only lasts around 1.5ms though)
• Instrument list: Fix opening the instrument list window.
