Creating a driver for JSynthLib and the Roland SPD-11

Back in 1998, I bought my first 600 neuro computer to get started with the official Cubase Vst 3.5, priced that day at 'only' 400 neuros. All my saved money was gone, I didn't have a decent job, but my future regarding recording music seemed secured, with an official dongle. it also didn't take long to get the blues 'cause my computer wasn't fast enough to run Vst plugins and the manual said I would also need a professional sound card.

It took until January 2004 before I first got a web connection and learned that Cubase Vst 3.5 wasn't supported anymore. The drivers I had been working on with dmaker were only useful for unsupported and expensive but 'old' software.

Now with Linux running, I use JSynthLib to edit and save the programs and banks on my Korg X3 synth, and I would like to do the same with my Roland SPD-11 but there's no driver been written yet.

I've read a book about Java and done most of the exercises but I'm still pretty new to programming, so it's a new challenge :-)
To make things a bit easier for myself and possibly others who may want to contribute/learn,
I quickly set up this wiki at spd-11.wikispaces.com.

And for now, I'll STFU and get on with my "unemployed status" job of writing the damn driver.
Cheers ;-)

fxload doesn't load the midisport 2x2 usb at boot

Since I installed the Ubuntu 8.10 generic kernel, (to get rid of a current multicore cpu bug in the -rt kernel version), the midisport 2x2 in my setup isn't loaded at boot anymore.

A quick way to fix it are these three commands:

Do this to remember the x and y values

:~$ lsusb | grep Midi
Bus 00x Device 00y: ID 0763:1001 Midiman MidiSport 2x2

Let the usb filesystems come to the kernel

:~$ sudo mount -t usbfs usbfs /proc/bus/usb/

Load the fish into the usb filesystem with the x and y values you just noted on your hand.

:~$ fxload -I /etc/firmware/ezusbmidi2x2.ihx -D /proc/bus/usb/00x/00y

If you see the little one come to life with a flashing led,
all is well and you can say 'it's OK'.
Man, I feel like I'm helping to write a new Bible, lol.

dmidecode on a Medion PC

dmidecode, a DMI decoder, can read information described in the BIOS about some hardware like the motherboard and processor.

It appears like Medion also is a motherboard manufacturer, I didn't know that.
The output of dmidecode -q on a Medion Akoya E5310D isn't quiet at all, so I used the option -s with some strings:

peter@ubustu:~$ sudo dmidecode -s baseboard-product-name
MS-7501

In case anyone needs more info, I'll paste the "quiet" output below .

I had to use the -q option to make dmidecode show the manufacturer's name and the board's BIOS version.
