    Default Still an occasional problem

    I've attached the most recent version.

    Once in a while, for no apparent reason, or after a RECORD cycle, when TRIGR is activated (with MFLAG set to 0), the program appears to jump directly to NOTCLR.

    How long does the interrupt service in TIMER take? I'm sure it's a matter of microseconds, but how many using DT_INTS-14?

    Is it possible that, if TRIGR goes high during the very short time while the interrupt is being serviced, the routine is going to skip going to PLAY and instead will go to NOTCLR?

    And, if so, what is the best solution?

    "Easy to use" is easy to say.
