Hi,
I still learn how to create drum kits using samples stored at the MOXF flash memory module. When setting up the drum-sound to key layout I would perefer be compatible with the preset drum apreggios (rhythms). In the data list GM DRUM STEREO GM KIT there is a table without the note numbers. In John Melas Wave Editor I have to enter these note numbers when setting up keybanks in the waveform for my drumkit.
Actually I notice a difference in the note numbers of Yamaha and the GM standard:

Standard GM-Drum-Map with note numbers:

Wikipedia shows this:

Where can I get such a table with the correct Yamaha MOXF Dum Note numbers and notes names ?

In the data list GM DRUM STEREO GM KIT there is a table without the note numbers.

In my data list there are note numbers for each of the MOXF’s drum kits. The GM Drum Stereo GM Kit appears to be compatible with the GM standard, with some extra drum sounds above and below the standard key range.

{...} Where can I get such a table with the correct Yamaha MOXF Dum Note numbers and notes names ?

The standard GM Level 1 Drum assignment is note numbers 35~81, corresponding to B0~C4.
http://www.midi.org/techspecs/gm1sound.php
The Wikipedia diagram covers the GM Level 1 assignment of those 47 notes.

Yamaha Drum Kits are assigned to 73 keys, C0~C6, note numbers 24~96. That’s 26 more notes than the GM Level 1 specification.

The GM Drum Stereo GM Kit table on page 31 of the MOXF Data List gives the Note Names (to Yamaha convention) and the Yamaha Wave Names (which don’t necessarily correspond to the GM naming standard).

I don’t have a MOXF, but my XS and XF agree with the GM standard, within the range of notes it covers.

Can you give some specific differences between the GM standard and what you’re experiencing with the MOXF?

Here’s a text version of the GM list, which you could edit for your own needs:

May you tell on which page of the MOXF Data List you saw this numbers ?
Here are on page 31 only WAVEFORM NUMBERS but no corresponding Midi Note numbers.

I have only a theory now. I am not telling there is something wrong. But there is some free space of interpretation of this GM standard for music instrument manufacturers.
I think the point is how the key range is counted.
Ex. C0 ... C6 or C-1 ... C8 ...

I will check what note number my MOXF sends for a defined key with a MIDI Monitor program. Then we well see…

You’re right, there are note names, not numbers, but the assignment between note names and numbers is well known. Find attached a .xls that gives you both. You may use ist as a blueprint for other drum kits.

Yes, which is why I said (emphasis added): “the MOXF Data List gives the Note Names (to Yamaha convention)”

 

popsel2 -

I’ve checked previously using MIDI-OX, and at least with my XS and XF, all is OK.

If Melas’ programs don’t agree with Yamaha’s convention, then that’s something he should correct.

I don’t want to blame anybody.
Here is what I get when the GM DRUM STEREO GM KIT is selected without transpose and octave shift:

Result after touching the lowest key, middle C and the highest key.
The “Data1” column shows the incoming MIDI NOTE NUMBER
There is a value of 36 and beside the note name: C2
The General MIDI Specification says for note number 36 the note name C3 and the Bass Drum instrument.
But here I get a C2 for a value of 36.

Next I switch to drum element edit to be able to show the name of my lowest touched key: Surprise

Lowest key and what my MOXF6 displays:

Ok, now I am confused.
The computer prints a C2 for my lowest MOXF6 key.
The Midi Specification says this note note number (36) is a C3 note.
The MOXF display shows a C1 for this key.

Can anybody explain this result ?

Lack of standard (convention).

It’s not a matter of blame. Even if other programs don’t agree with Yamaha note naming and numbering, the Melas programs are written specifically for the Yamaha synths. It would seem that there should be agreement, if there isn’t already.

Why not set C3 = middle C

In MIDI-Ox
Click on OPTIONS > GENERAL > set middle C to 3

Because this would not slove my problem.

I want to create own drumsets compatible with Yamaha layout,
so I can use the preprogrammed drum apreggios with my own drum set and use standard midi drum loops, too.
For this task I need to know the correct midi note numbers Yamaha uses to create the keybanks in the Wave Editor.

Example:
Create a Keybank using a single key with value of 36 for the Bass Drum (Gemeral MIDI Standard).
After saving the X3A file and import the drum set voice to the MOXF6 this keybank
is not at the position it should be for a MOXF6 GM bass drum.
Then my drumset is no longer compatible with GM and the preset drum apreggios.

Do you know what I mean ?

What position does it wind up at?

Hmmm,

the lowest MOXF6 key is C1 (value from display).
This is equal with a note value of 36 and should be the bass drum as in the GM standard (C3).

C1 <==> C3
So there is a difference of 2 octaves.

I think then I need to subtract 24 (2 octaves) from each note number in the GM standard to receive the correct layout on the MOXF6.

I need some time to check it…

Hi,

after creating a “drum set” containing a single drum sample at C3 (as General Midi Standard) and import X3A file to my MOXF6 this is the result:

The drum sample is positioned at C3 key.

The GM standard says this is the reserved key for the BASS DRUM.
At my MOXF6 this should be at C1 (2 octaves lower).
So I think I really have to subtract 24 from each GM note number to receive a MOXF6 conform GM drumset.

Hi,

interesting, it seems to me nobody knows Yamaha’s drum layout with the correct note numbers ?

Finally I can answer my question myself ;-)

I just found a very old Yamaha XG specification from 1998 and on page 63 there is what I was seeking for.

Yamaha’s General Midi Drum Map is shifted 2 octaves down, compared to the official Genreal Midi Standard.
Very interesting. I have had expected at least the note numbers in the MOXF Data List if Yamaha shifts the notes by 2 octaves.

Here is a partitally screenshot.
I’ve attached the full PDF document for those people who want to create own drum sets, too.
