Re: Re: Yamaha WT11 factory patches / performances, on a TX81Z?

> In the SysEx specs I see room for an 8-bit value (7 bits in one byte, 1 bit (MSB) in another byte) allowing 256 values.

It could be.  The manual I have is a slightly blurry scan.  I see b4 of param 0 of each instrument says MSB, but it doesn't say what it's the MSB of.  Param 2 is 7 bits and it says VOICE NO (without LSB), so that seems reasonable.

The "Secret Mode" user interface only allows a number from 0-127 to be selected for vmem_num (I just checked), but maybe the ROM is allowed to address ones we're not allowed to choose.  Have you found any examples where that bit is set?

I could edit a performance dump with a hex editor, to experiment, but I'd have to find out how to make the checksum right... I'm not sure if it would reject the transfer if it's wrong, or just complain.  I'll have to look into it.

Incidentally, the WT11 Secret Mode.pdf says "Edit inst?" (for choosing the instrument to edit in the performance) can be from 1-3.  That's wrong, of course; it can be from 1-8.  It seems odd that that's been in circulation for so long and no one corrected it.... or maybe someone did, and there are now multiple versions of it.
