Add more presets

I suspect I'm doing this wrong, as there are 192 presets, and MIDI
only allows selecting of 127 programs.  MIDI has a bank select, kind
of like paging, which might be what shift mode is hinting at in the
DX-100's manual, I'm not sure.  (Page 9.) At any rate, I don't have
a DX-100, so can't verify how it works.

Let's leave it like this for now.  Hopefully others will improve on
it one day if needed.
Add TX-81Z presets

Except I missed one, ack!

Note "French Horn" is a mistake in the instruction book, assuming
the LCD only has room for 10 chars of preset name.

Of note, B21 "HiString 1" sounds very AFXey (he apparently used a
DX-100 according to DRN, which I gather is simlar to the TX-81Z),
and C15 "LatelyBass" is a classic.

I don't have one of these yet.

Add another module's presets

I don't have any of these modules...  I'm just going by the instruction
books.
Add presets for another module I don't have... :)
