[comp.sys.ibm.pc.misc] Questions on HRS-401

Hello,

I just bought a HRS-401 (PC Music Maker/MPU-401 compatible) for my PC.
It is a half size internal card with 1 midi-in, 1 midi-out, and a
phono jack.

The question is that the manual does not mention anything about the
misterious phono jack.  I assumed that it was a metronom(spell???) output,
so I connected it to an amplifier.  Yes, it was a metronom output.
However, it also produced a lot of static noise, and the metronom sound
was horrible.  The sequencing software that comes with the card
uses internal PC speaker or a midi channel to generate the metronom sound
and does not seem to make use of that jack.

Does anyone have any idea what's going on?
Any comments/explanation will be appreciated.



P.S. By the way, Does any one know whether HRS-3000 (which seems to be
an external version of HRS-401) is an MPU-401 compatible?
