New in AUM 1.4.0


ENGINE

- Add 64kHz sample rate option.
- Add 'DJ style' combined LP/HP filter node.
- Make Transport Clock sample-precise when Ableton Link is disabled.
- Send reset to AUv3 when changing bypass state. Can (should) be used to clear delay lines etc.
- AUv3: don't process bypassed nodes.

When an AUv3 plugin is loaded from a session in AUM, this is the order of things that happens:

• If there already was a session loaded, it's saved to a hidden file (for Restore Last State).
• Wait for above state save to finish.
• The new AUM session is read from file, loading session title, notes, etc.
• Reads and sets session properties like sample rate, minimumLatency, metronome, and state for all HW and Mix busses.
• Empty channel objects are created for all channels in the session.
• Wait for this to finish.
• Loads the nodes for all channels:
• Create the node object.
