Korg KARMA Frequently Asked Questions Manual page 20

There is nothing you can do about this, other than to leave a certain
amount of time after a mode change before sending the program change
or other MIDI CCs. My KARMA software, which allows mode changing via
SysEx, does this exact thing. It delays about 200 ms or so after the mode
change before sending any other MIDI data.
12. Can the Karma respond to Sysex Song Select messages in lsb-
msb or msb-lsb format (or any other method)? I tried SysEx, but
it doesn't seem to work.
A "Song Select" message is a "System Common Message", not a "System
Exclusive Message".
Incidentally, that reminds me to suggest an excellent TECHNICAL book
on MIDI, numbers, hexadecimal, binary etc. In fact, I had to go back
there to look up some of the info that I'm telling you here. It's called:
"The Next MIDI Book - Starting with the Numbers" by Lorenz Rychner
with Dan Walker, published by Alexander Publishing. Who knows if it's
still available – I've had this for 10 years at least.
In other words, you do not send F0 and F7 with this info inside it. Just
send "F3 xxx" to select your song. A quick lesson in MIDI:
A "Byte" is 8 bits. There are 2 kinds of Bytes in MIDI: a "Status Byte"
and a "Data Byte". In order to differentiate between these two types of
Bytes, the 8th bit in a Status Byte is "1", and "0" in a Data Byte. As a
consequence of the 8th bit being 0 in a Data byte, it is only capable of
using the other 7 bits to express the value. A 7-bit number goes from
0~127(128 values). As a result of the 8th bit being 1 in a Status Byte, its
minimum value is 128, and it goes from 128~255.
The Status Byte indicates what kind of message it is, and the Data Byte
indicates the value, i.e. Status "9x" for note-ons (where x is the channel,
from 0~F), or Pitch Bend "Ex", etc., with the Data Byte telling the actual
note number, or pitch bend value.
In this case, for System Common Message "Song Select", the Status Byte
is "F3" and the Data Byte is "xxx" being the song number from 0~127.
