gosh! I was wrong! offset MUST BE >= start-position
Ok. Problem: I have a sample quite large from wich I want to play a
little piece in the middle of it mixed with others chains in the
starting position of my play. How can i do it?
I thinked to shift all the chain's offset but now I need to start
ecasound at a given position for all the chains and I do not see any
command line switch to do it. I see the general time limit command (-t)
but not the global start...
For the fading (ghosh^2) I'm telling myself RTFM all the time...
from man ecasound...
Linear envelope that starts from 'start_value' and
linearly changes to 'end_value' during
'time_in_seconds'. Can be used for fadeins and
Two-stage linear envelope, a more versatile tool
for doing fade-ins and fade-outs. Stays at
'start_value' for '1st_stage_length' seconds and
then linearly changes towards 'end_value' during
so problem solved...
sorry for the noise on this list...
