Aloha M,
Ahhh! ‘MIDI 101’ I see.
I posted a modified version of this post in another thread.
Hope it helps you to understand this part of the MIDI protocol.
_Depending on how they were made
.MID files from 3rd party sources can
have mucho MIDI events buried in them.
In your case there are MIDI ‘Program Change’ messages in that file(s)
telling what ever sound source you are using to play a certain sound.
You need to delete those messages and insert yer own.
This is where the Cubase ‘List Editor’ feature can really help
to find and then delete those 3rd party MIDI PC messages.
Using the LE
1- Using the ‘Focus’ feature first locate and delete
all ‘Program Change’ messages thru out the track then
2-in the very beginning of the MIDI track, insert
a PC message/event that brings up the sound you want.
As long as there are no other PC events on that track
(or any that are on another track but are on the same MIDI ‘channel’)
YOUR sound(s) will play thru the entire song._
So when you say:
drums turn into odd keyboards sounds
This is because there is a lil MIDI cop (Program Change message) telling any MIDI event that walks on that street (track)
to only make a piano sound.
For that specific street we need to change that ‘piano cop’ and put in a ‘drum cop’.
Get it yet?
HTH (hope this helps)
