Hi,
all you need to get started is the list of voices provided by the
device. The attached bash (mine) and Python scripts (provided
by Ryurick M. Hristev <ryurick.hris...@canterbury.ac.nz>) should
do the rest.
Regards.

Hi,
I'm VERY new to Rosegarden, and MIDI devices in general. I'm on a
Pop!_OS 20.04 Linux box (effectively Ubuntu 20.04), running Rosegarden
19.12. Someone sold me a used Yamaha PSR-220 cheap, and it seems to
be in good working condition -- not that I've ever had a keyboard
before.
So. As I understand things, it would be nice to have an ".rgd" file
that corresponds to my keyboard. I couldn't find such a file, but
decided to see if I could create one. (It wasn't obvious to me that
the existing ones were gzipped, but I found that out when I tried to
edit one.)
A few questions then:
1. Is there already a PSR-220 file somewhere? If so, where?
2. If not, is there a good description of how to create one? Looking
at a gunzipped Yamaha-PSR-E223-YPT-220.rgd, it looks like there's an
awful lot of info that I'm not certain how to collect.
Thanks!

# txt2rgd:
#
# DESCR: Converts from a text based voice list of an instrument/sound card
# to the XML mased *.rgd format understood by Rosegarden
#
# USAGE: txt2rgd <input file> <output file>
#
# where the input file contains the voice list in text format
# and the output file is the name/location of the *.rgd file
# to be generated
#
# The format of the imput file is any reasonable space or comma
# separated (CSV) list of parameters:
# a. comments start with '#' and continue to the end of the line
# and may occur anywhere
# b. blank lines (or containing whitespace and/or comments only)
# are ignored
# c. any line containing data must have 5 fields (+ comments, ignored):
# <user marker> <MSB> <LSB> <Prog#> <Voice> # optional comment
# where:
# <user marker> is a field used to help data entry,
# could be anything, e.g. voice number
# but must not contain whitespace, ',' or '#'
# this field is ignored in the output
# <MSB> MSB (Most Significant Byte) of the bank number
# range 0-127
# <LSB> LSB (Least Significant Byte) of the bank number
# range 0-127
# <Prog#> Program number of the voice witin the current bank
# range 1-128
# <Voice> The name of the voice as desired
# it is best to type it in as specified by the
# manufacturer or the GM/XG/GS standard if available
#
# MSB and LSB are 0 for the GM only instruments.
#
# Given the notes 2 & 3 some manual intervention on the output
# may be required to achieve best results.
#
# NOTES: 1. This script may use features available only in Python 2.2 and above
# 2. The device 'id' and 'name' tags are hardwired
# (apparently the id must be 0)
# 3. If possible we try to guess a bank name according to XG
# otherwise the bank name is autogenerated as "<MSB>-<LSB>"
#
# BUGS: 1. The name of the voice can't contain the ',' and '#'
#
# WARNING: 1. The output file will be overwritten if it already exists

# - The voices in banks 1 - 8 are essentially similar to their GM equivalent
# in bank 0, with only minor (though often highly effective) modifications.
# - The voices in banks 9 - 15 differ from their GM counterparts mainly by
# having different AEG (Amplifier Envelope Generator) settings.
# - The voices in banks 16 - 23 differ from their GM counterparts mainly by
# having different filter settings.
# - The voices in banks 24 - 31 differ from their GM counterparts mainly by
# having different FEG (Filter Envelope Generator) settings.
# - The voices in banks 32 - 39 differ from their GM counterparts mainly by
# layering two elements and then detuning the elements or changing their
# pitch relative to one another in various ways.
# - The voices in banks 40 - 47 differ from their GM counterparts mainly by
# layering two elements, with the new wave different from the basic one.
# - Banks 48 - 63 are reserved for future use.
# - The voices in banks 64 - 72 differ from their GM counterparts in that
# they use a different wavetable (though they are designed to create a
# similar kind of sound).
# - The voices in banks 96 - 101 often have little or no resemblance to their
# GM counterpart.
# - Banks 112 - 127 may be used by future XG instruments for the
# storage of user-created voices.
