Hi,
Im afraid I cannot understand the way your opcodes

  schedule        inst, iwhen, idur, ....
  schedwhen       ktrigger, kinst, kwhen, kdur, ....

are supposed to work.
schedule always triggers the instrument when it is called, no matter the
iwhen parameter. Also, if  I put a schedule opcode inside a timout/reinit
statement to trigger an instrument several times strange things happen: it
seems that from the third activated event they are not turn off after idur.
Schedwhen seems even more strange to me, as it hangs Csound when ktrigger >
0 , no matter kwhen.
Any help would be greatly welcome!! Im very excited with these new opcodes!

Thancks again in advance!!!!
