Thanks to ArKay and Rick for the feedback.

The best solution is to use a card reader that does not tamper with the data on it thus making the files unreadable to the QY100. Some people have had success with this but were vague on the?
exact details of the model. I was unable to find any information detailing a brand and model id that is safe to use and still in production. If anyone reading this knows of such a card reader
then please post a message with this information. It's the best solution because you can backup all of your data at once rather than having to work with a maximum of 18? songs at a time enforced
by the limits of the QY100 memory capacity. It's also a lot faster because you eliminate the QY100 and the Datafiler?software from the process saving the time required to load files from the card
into to the QY100 and then transfer them via the Datafiler?to the computer.
?
It's still best to back up the data before trying the card reader just in case of unforeseen problems. I would have just bought a better usb midi adapter but the pro models cost a lot and
ebay sellers of older models that people had used with success wanted a lot of money as well.?
?
I wondered if the problem had something to with the fact that during back up midi sysex message are used and the rate at which the data is exchanged might be faster than normal possibly leading to?
buffer overflow in the usb midi adapter. Backing up data from the QY100 to the computer worked but when I tested transferring files from the computer to the QY100 this did not work.
If this is the case then I figured that if there was a way to slow things down via software then it should solve the problem. If I understand correctly the free software I used: MIDI-OX & MIDI Yoke sit in between the?
computer and the QY100 and slow the message exchange rate down. MIDI-OX has an option to pause after the end of a sysex message (Delay after F7). The default settings worked for me. If you have problems
the user forum for MIDI-OX is active and the mods are intelligent and offer great responses to questions.?
?
The MIDI-OX website has all the information you need to learn about it so I leave it up to the reader to take advantage of that.
?
Here are the settings I used for MIDI-OX:
?
Open two instances of Midi-Ox. I saved these as the following profiles QY100 backup input.ini and QY100 backup output.ini
?
QY100 backup input.ini deals with USB-MIDI input port.
?
USB Audio Device is the name given to the usb midi adapter I used.
?
In Midi Devices, MIDI Inputs select USB Audio Device
In Midi Devices, MIDI Outputs select Out To MIDI Yoke: 1
?
In the Port Routing screen USB Audio Device and MIDI-OX Event Port should both be connected to OutTo MIDI Yoke: 1
?
QY100 backup output.ini deals with USB-MIDI output port.
?
In Midi Devices, MIDI Inputs select In From MIDI Yoke: 2
In Midi Devices, MIDI Outputs select USB Audio Device
?
In the Port Routing screen In From MIDI Yoke: 2 and MIDI-OX Event Port should both be connected to USB Audio Device:
?
Input Ports Output Ports
In From MIDI Yoke: 2 USB Audio Device
MIDI-OX Event Port?
?
In the Datafiler software make sure you select the following connections:
?
DataFiler MIDI IN: In From MIDI Yoke: 1
DataFiler MIDI OUT: Out to MIDI Yoke: 2
?
Sequence:
?
Start the Midi-Ox instances first
then the QY100
then the Data Filer
?
If you want to examine the contents of a bulk file create a copy of it first and examine that.
I am not sure but opening them in Notepad might introduce new data and cause a checksum error.
?
If anyone from Yamaha ever reads this there are a lot of people that very much like the QY100 and would certainly buy an updated model. I have a bunch of features I would like
see in it and I know it's possible to make a device that would dominate the market. It could also absorb the functionality of phrase trainers, mini multitrack recorders etc.
Boss/Roland get in touch if you are reading this, lol.
?
Finally if anyone has a list of the musicians who worked on the QY100 the please share. This device if used well is perhaps the best thing you can ever buy to grow musically.
I know a lot of people use computers but there are issues with portability and software problems with them. I want as few problems as possible in the way when it's time for music.
