Subroups, aux busses and quality loss

Postby tas » Mon Nov 21, 2011 20:37

So I have been discussing and reading on the use of busses in DAWs an how the summing that plakes is bad practice because resolution is cut down. Subsequently it depends on what resolution these busses have themselves ranging from 32 to 64 bit. If I understand correctly the 32-bit version of PT has 48bit busses and I think Reaper 64 so I was wondering what its like in PMX and what people do as best practice.
Do you avoid using sub busses when possible?

Pyramix uses 32 bit Floating Point math internally. Floating point means that it's essentially a 24 bit word with an 8 bit mantissa, which is a neat way to maintain resolution, regardless of level.

There is, to my ears at least, no degradation when using Pyramix' internal buses and subgroups. As fl stated it's a 32 bit FP pipeline and only gets converted back to 24-bit integer mode at the AES output (or whatever your output format is).

Clearly heard what you're talking about in a Yamaha PM2000. Never heard any loss of quality in Pyramix, and I do some crazy sub grouping.
