Hi Developers,

  Related to this topic just out of curiosity, does the Victor
Lazzarini tablew Pitch Shifter [1] now compile with Csound5 ? Does it
require the setksmps 1 line ?

  Given the current, revised behaviour, (in this example) is it
recommended to use all control rate signals and upsamp at the end or
just deal in all audio (ie.  aout  tablew  andx, itab) or possibly
some other solution ?

  Are the new messages printed to the console printed at all message levels ?

  Apologies for all the questions, but SourceForge anonymous pserver
access is not yet synchronized to the latest developer updates
concerning the topic of this thread.


Thanks in advance,


-David
