What is the maximum number of internal busses in Pro Tools?

The maximum number of internal busses in Pro Tools is indeed 256. Internal busses are crucial for routing audio within a session, allowing users to mix sounds from various tracks effectively. This large number of busses offers users substantial flexibility in managing their audio routing, particularly in complex sessions that involve numerous audio sources and processing.

Having 256 internal busses facilitates advanced mixing techniques and creative routing options, such as setting up parallel processing chains or creating unique submixes without needing to rely on external hardware. This capability is particularly beneficial for audio engineers and producers who work with large projects, as it empowers them to keep the workflow streamlined and organized.

The other options represent lower limits that would be insufficient for many modern mixing scenarios, especially in professional music production or post-production environments where extensive routing might be necessary.
