Hi,

The problem is that the grain opcode will crash if you set the grain
duration to 0. So you need to change this line:

kgdur midic7 4, 0, .25

to:

kgdur midic7 4, 0.001, .25

Would it be good to check this at perftime and generate a perf-error
instead of a crash?

Cheers,
Andrés

I have added a check for kglen beingf strictly positive.
Or should it give it a default value?

One millisecond seems right to me if the user sets it to 0.

Hi,

I prefer the error as John has suggested. Otherwise you might
undesired results without warning.

Cheers,
