This is not true.. Read posts #47 & 48 above.
There are definitely some who have, through repetition, created a widespread notion that DSD can't be edited, but the claim has always been dishonest. This is because of how they define what "editing" is. DSD definitely can be edited in the conventional sense, it can have volume changes, and even multiple channels can be mixed in Sonoma.
What certain DSD detractors have done is redefine "editing" into things like digital EQ, autotune, unlimited multichannel mixing, digital reverb, sampling etc. When they say "DSD can't be edited", they really mean that DSD isn't capable of advanced DSP and complex in-the-box digital production like is done with modern pop. Most us would not call that editing.
The criticism also implies that good recordings can't be produced outside of an ITB digital plugin environment. The reverse is often true: Most of the best recordings historically have little to zero digital processing (I'm excluding reverb etc). Pyramix and Sonoma (and the old Genex system) can be used exactly like a tape machine, but with
more editing and track capability, and provide
higher sound quality in an analog mix or mastering environment than is possible with PCM ITB projects. There is a lot of misinformation.
