You probably don't need the cash with all the green stuff rolling in
from Powerchords! :-)

This is the midi controller set 'Registered Parameter Number' (RPN).
The MSB is 101 and the LSB is 100. There are only 4 RPN's defined
in the Midi Spec:
0 0 - Pitchbend Sensitivity (data from 0-24)
0 1 - Master Fine Tuning (data from 0-16383 [-8192 0 +8191])
0 2 - Master Coarse Tuning
127 127 - RPN Reset (Maybe not necessary for the GUS, but I've always
seen it used after any RPN event)
The data-entry controllers are 6 (MSB) and 38 (LSB). Only 'Master Fine
Tuning' uses the LSB, and 'RPN Reset' uses NO data entry. (The data-entry
controllers also get used for NRPN events, but I think GUS has
none defined.)

Because the LSB is ignored for the pitchbend range, you need not set
controller 38. The midi spec defines the value to be semitones, and the
GM spec defines the default to be 2 semitones, with a range from 0 to
24 semitones. Note that non-GM synths sometimes set this VERY differently:
The Yamaha Diskclavier defaults to 3(!) semitones, and the old Adlib
FM sound boards default to 4 semitones!
Always happy to try to help someone from Texas!

I have no problem supporting memory above 256k with Wincake2.0 on my GUS.

12 Tone Systems uses Compuserv for a BBS.

The only patch-caching problem I'm aware of concerns using patches in channel
10. This causes Wincake to complain that there is not enough memory. Remove
the patch from channel 10 (drum channel) and everything works fine. TTS
has stated that they will fix this, but it has not happened yet.

Yup. The default range for the General MIDI set is 2 semitones, up and down.
