Optimizing the number of displayed sources
The maximum number of sources that can be displayed can be significantly increased
if you display them at less than their native spatial resolution. For example, if sources
are displayed at one quarter of their native spatial resolution, the RAPT bus can
accommodate four times as many sources while preserving full temporal resolution.
