MIDI control question - how do I do this?

[jjm542]

I would like to set up my CVP900 so that when I'm playing midi files from the floppy, I can route some of the channels to midi out and suppress those channels from playing the internal voices. Setting the "song" channels to "on" solves the first problem (routes the midi channel to midi out) but it still plays the internal voice. Can anybody help? Midi Magic?

thanks,

Hi jjm


I see you have found the first answer. Go into the Midi Page and turn midi TX on.

The second is even easier, but you WILL have to do it each time and for each new song.

Just go to "Channel On/ Off" and turn off the channels you don't want. That will stop them playing the 900. I have NOT checked to see if that turns off the midi out though.

The hard way is to modify the midi file. If the other keyboard has "Bank Numbers" then you can give the channels you DON'T want to play the 900 a bank number that the 900 does NOT have and the keyboard has. Does that make sense ???

Try the easier solution first and see what happens.

Hi jjm


I have just tried it and sorry the turning off of the channels also seems to turn off the midi out.

What is the other keyboard / module ?

Maybe you could play the midi file from the PC and use the "Thru" to the other keyboard. Then you can turn off the channels on the 900 and all of the channels will go to the other device.


Just an idea.

Thanks Midi Magic. I should have said that I had already tried turning off the (piano track) channels and found that it also turned the Tx off. The midi implementation of the CVP leaves something to be desired as a master keyboard, although I'm sure Yamaha didn't see that as its primary use.

I suspect the "thru" trick would work, but it would be cumbersome. I don't mind modifying the midi file but don't understand how to manipulate the "bank" number. I presume I need to use some kind of editor - can you recommend one (PC or Mac)? The tone module I want to use for the piano sound is GigaStudio, a soft synth running on a PC.
Thanks,
jim

Hi jjm

You could use a PC program or the edit function on the 900.

Here is some info on Bank Changes, or here is one I prepaered earlier. If you give the piano a bank number it has not got the CVP will not play anything. ( This is why I wrote this in answer do someone elses question.)
Hopefuly the PC GigaStudio will ignore the bank change and just play the program change.

Hope that makes sense.

Here is some info on the MSB LSB.

First arm yourself with the "Reference Booklet" (CVP2xx) on page 3 you will see all of the Voices and a list of numbers.

Under ORGAN you will see Rotor Organ MSB 0 LSB 112 Program Change 18

Control Change 0 0
Control Change 0 112
Program Change 18

The MSB stands for "Most Significant Bit" and
LSB stands for "Least Significant Bit" which makes the CVP do
a "Bank Change" you then issue a Program Change.
These Bank changes allow you to select different voices over and
above the basic, ie a program change of 19 will give you Pipe Organ.
But you will see from the list there is more then one voice 19.
The other voices live in different banks. (112, 115, 116, 113 etc)

On the CVP it looks like this:

Ctrl 0 112 Bank MSB
Ctrl 32 0 Bank LSB
Prg 18

What you did was correct, or you could have looked in the book and changed the 121 into a bank that we DO have.

BTW, If you go to "Function" "Utility" "Config 2" you will see "Display voice number:" Select ON

Now when you select a voice from the piano's panel you will see the full bank number of each voice. #000-122-000 is the Grand Piano 1
