DATE: January 28, 1993
KEY WORDS: GUS MIDI CABLE CONNECTOR INTERFACE
SUBJECT: How to build a MIDI cable that will work with the GUS
The Gravis MIDI connector box will not be available until April '93.
In the mean time you have two options if you want an immediate solution.
First, you may purchase a Sound Blaster MIDI Cable from Creative Labs,
NOT their MIDI connector box. Then make the following modification to
1) Change the 6N136 IC in the cable (inside the end that plugs into the
sound card) to a 6N138
2) Add a 5.6K resistor (GRN BLU RED) between pins 6 & 8 and another
one between 5 & 7 on the 6N138 (easier if you put them on the
underside of the circuit board).
Your second choice is to purchase a MIDI cable from MediaVision that
does not require any modifications. You may contact them at:
47221 Fremont Blvd.
Fremont, CA, USA
For information on how to build your own Sound Blaster MIDI cable,
please refer to MIDDIA.ZIP, which you may find on the Gravis Support BBS.
NOTE: Running SBOS V1.22 or earlier then pressing a key or sending ANY
MIDI data WILL crash your system!! This problem is being worked
on. (CURRENT PRIORITY: LOW-MID)
