Joe, You da MAN!

I knew it has to do with the LSB thing but I don't know how to.

Can you please walk us through this process?

What needs to look for and how to choose LSB accordingly? this is an uncharted territory to me, so please teach us how to do that, please!

mheuzeroth,

In MIDI, there are 3 messages for every Voice or sound.  The MIDI specification created what are called "Banks" of sounds.  There are 2 sets of banks. The Most Significant Byte (MSB).  These are numbered 0 - 127.  Each of those banks has 128 banks (0 - 127)... that is the Least Significant Byte (LSB) This makes a total of 16,384 possible banks of sounds.  The 3rd message is called a Program change (PC) which also has a numbering system of 0 - 127 (displayed as 1 - 128)

So... the Voice message is written: MSB  LSB  PC.  An actual message might look like this:  104  030 039 this is the message for Deep Point Bass.

On the Expansion packs, Yamaha has set all MSB messages as 063 for Normal Voices and 062 for Drum Kits. 
So an expansion Voice may look like this:  063  048 088 and for a drum kit it will look something like this: 062  000 001.

The YEM software allows us to change the LSB number so that no 2 packs will have the same number. and therefore confusing the keyboard. The MSB will always remain 063  and 062.  So we can have up to 128 packs loaded into YEM and each will have a different LSB number.

I hope I explained things well enough for you to get the gist of it.

I would think the S970 expansion packs will work on the S975.

Do you have experience with using the YEM software?

Hi, could you help me out,  please?
What does LSB Assignment mean? And what does LSB stand for?

Thanks

There are 3 Voice messages.  2 Bank Select messages which are: Most Significant Byte (MSB) and Least Significant Byte (LSB) followed by a Program Change (PC)

An example would be written: (MSB LSB PC) :  104 002 039 which the S970 Club Bass. Which in MIDI is written 104 002 038.  The reason being the PC numbers in MIDI are actually written as 000 - 127, but Yamaha chooses to display the PC numbers as 001 - 128

The MSB bank has 128 numbers and the LSB bank has 128 numbers. (Each MSB Voice Bank has 128 banks)  That's 128 x 128 and there are 128 Voice numbers... so an instrument potentially could have 16,384 Voices.

Hope this sheds some light on the subject.

Well I haven't tried the Ghenos Pack(cause I don't know what's in it - so hesitating to purchase) but I've tried a lot of 970 packs - they all work fine as well as 3d party packs and also EDM packs from Jan.
