Further to Julie's comments,

I am a little confused about this thread, having seen the SD card to
midi adapter on Ebay I was interested from the point of view that
Floppy Disk players are no longer fitted to new computers, these
disks are an old technology and I have had many disks that for some
reason will no longer play.
I would like something small that could be used on the two Street
Organs that I have built and fitted with my own design solenoid
manifolds.
Presently I use a Casio FD1 player which is bulky compared to the
Ebay device.It is for the same reason that I am interested in the E-
valves which are less bulky than my own manifolds.
To compare the use on a Fair Ground Organ is missing out on the need
Street Organ grinders have for a compact device which will operate
from small batteries for several hours without having the back up of
a generator or mains power.

Regarding the capacity of the SD cards it is nice to know that they
will hold such a large number of MIDI files but why would I want so
many on a single card. My main library if and when I get one will be
kept on my home based PC or Laptop and I intend to use several SD
cards of small capacity which will reduce any searching to say no
more than 20 tunes and these tunes will be grouped say for classics,
birthdays, dance, easy listening and so on.(the build up of my
library is a problem my organs are 26note Ian Alderman scale and the
Zillions of midi files said to be available on the web are not
suitable without much work via Cakewalk or other such programme and
a knowledge of music arranging)
Yes I have tried Van Bascoe's and being able to group the tunes for
copying to another device is an attraction.
I have seen a demonstration of the Ebay SD to Midi device and
thought that it would fulfil my needs and that of many others who
want portability and small size.
The Ebay Buy-now price I considered to be a little high but I
understand it has now been set at £150.
I have no financial interest in this product but having spoken to
one of the developers I was told that a great ammount of money has
been invested and several years of design work has gone into the
product.
Incidentally the remote control will be ideal for tune selection
without having to climb in and out of a vehicle or leaving the
person you are talking to.
I have also seen this device supplying the midi file to operate a
piano and it sounded great, some clicking from the solenoids but
this is being worked on.
