i think pushing your slot onto *time-slots* is the best way -- I will add 'begin-time' to the list next release. the :time-parameter business is quite old and assumes that cm shadows clm:definstrument. but if clm doent complain about it then it still might work if you do something like:
(definstrument (foo :time-parameter whatever) (whatever dur frq amp) ...)
