Appendix A: DSP Requirements for TDM Plug-Ins 79
Multi-Mono and Multi-Channel DigiRack Plug-Ins
Plug-ins used in multi-mono format on greater-than-stereo tracks require one mono instance per
channel of the multi-channel audio format. A multi-mono EQ used on a 5.1 format track, for exam-
ple, requires six mono instances since there are six audio channels in the 5.1 format. Because multi-
channel versions of the Compressor II, Limiter II, and Expander/Gate II plug-ins are available for use
on greater-than-stereo tracks, separate instance counts are given for those configurations.
