Howdy. I'm currently beginning to employ some stereo control within csound (I do a lot of post-csound processing). And I'm not sure the x,y coordinate system is working as documented, although I'm sure someone will point out my user error : for the kx and ky parameters to pan, I'm trying to use an oscili signal to control the pan at rates of .5-3 cps. But the best way I can get it to work properly (i.e. nice even, full sine pan from one side to another) is in offset mode, normalized, and sending kx from .5 to 1.5 and back. I can't seem to get anything working in non-offset mode (get tiny or no signal out) in the -1 to +2 area. My ftable is either a line from 0 to 1 or a GEN02 sketch of a first quarter sine (per manual's sugg) ; and it seems to work just right either way with the setup above. Could it be that the offset is working the wrong way? That would put my .5-1.5 back in range.... but I hate to criticize others' code, especially something that other people have _got_ to be using regularly out there. BTW : How else might one 'automatically' generate a first quarter sine wav via gen routine?) Also : in a GEN02 routine, with an extended guard point specified (size = 65 or 1025 or the like): does one specify a value for the guard point or does csound take care of it? Any ideas appreciated. pax vobiscum thank you for your bandwidth |

Try using the new "locsig" and "space" units. there a bit more straight-forward. RK On Thu, 18 Jun 1998, QATJD wrote: > > Howdy.
