db50xg are quite rare and pretty expensive. i never found ebay auctions below 50€ or so.... i think that 50€ for a computer stuff more that 10 years old and unusable on modern PC are a lot of money!!  :D

the reason is that the daughterboard can be used also in masterkeyboards such as oberheim MC1000 or similar, in order to get new sounds.

anyway, if i could find one for very low money, i would definitely buy it!  :P

I recently saw an article in Nuts and Volts magazine (Feb 2009 edition, I think) showing a PIC based controller for the DB50XG. Had USB interface, but the PIC wasn't one we use here.

That's my design... I exchanged some notes and ideas early on with Thorsten about implementing USB-MIDI... he was good enough to run my routines through his test suite, too. The article was spread over the Feb/Mar 2009 issues of N&V.. all the code is on their site.

I'll be putting it up on my own site (www.grapevyne.com/pic.projects) in a month or so, and any new developments will go there as well.

Steve.

Great stuff stever, thanks for sharing it and especially congrats on your publishing :)

Thanks - I enjoyed developing the project, and being able to access and get pointers from resources such as this list made things easier than they might have been.

Hi,

I have found a helpful sites long time ago, for XG programming.

Maybe this is helpful for you.

XG programming:

alternative board design, but in german:

@Steve, nice project.  :)

Do you have created a board for preview?

Best Regards

This, or something like it, was what started me thinking about using my DB50XG for a project quite a few years ago... It was seeing the MIDI-Nator project that completed the puzzle and made me realise I could add a USB interface by using a suitable PIC device.

@Steve, nice project.  :)

Do you have created a board for preview?

Thanks for the compliment.

I've made a few changes since the initial design was published and have a prototype board back that seems to work fine... I'm working on an enclosure at the moment... I hope it will be done in a month or so (not much spare time!). The results will be on my website (www.grapevyne.com/pic.projects)... I hope to include PCB info.

Regards, Steve.

Badass! and a whopping 4x40 too :D

the program is available if you wish

I wish!!

(I can't find a DB50 lately, but if I do get one, I'll want this app for sure!)

Do you have schematics or anything like that? It would be really good to put this in the user projects forum I think :)

Hi Steve,

I am ready to build.

If have bought 5 DB60XG clone from NEC XR385 and 1 DB50XG.  :D

http://cgi.ebay.com.sg/Yamaha-DB50XG-DB60XG-Sound-Daughter-Board-SW1000XG_W0QQitemZ190296107746QQihZ009QQcategoryZ108984QQcmdZViewItem

And I already own a SW60XG as reference.

@stryd_one check your pm.

Best Regards

Jack

The DB60XG also includes an Line IN (Waveblaster connector 12 and 16). You can apply effects to it.

Years ago i build a a little board which was designed by the german electronic maganzine Elektor (http://www.elektor.de/jahrgang/1997/juli/synthesizer-mit-yamaha-db50xg-karte.61631.lynkx). The only problem with that is, that the PSU capacity is on the small side. I used it with a Korg Daughterboard which draws more power then the Yamaha DB50xg. So i had to make some modifications to it.

I recently bought a DB60XG clone from ebay (probably from the same guy  ;)). I want to build a 19 inch version with at least 2 daughterboards, so i can house both cards.

If you go and make something make sure you build a beafy PSU. These cards were allowed to draw a max of 500 mA from the 5V line. I expect the DB60XG to draw more power then the DB50XG since it includes additional IC (AK4510).

Well it took a little longer than I thought, but the project pages (mistralXG) on my site are now available. There are a couple of bug fixes available, along with the original articles I wrote and the N&V article.

Hi Steve,

It looks nice.  :)

I have a wish list:

  • optional Audio Input for the DB60XG
  • encoder for the menu
  • bigger display, e.g. 4x40 or 2x40 to display all channels, instruments, ...
  • support to save and load QS300-Voices over the memory

@joeribl

The PSU is not the problem, because it is external.

Can you try this midi files from Trond Olsen (except Indiana)? http://www.megatrade.ru/Russian/Midi.html

On my SW60XG they sound fine but on my DB50XG and DB60XG on a SB16Pro they sounds weird. Maybe there is a problem to load the QS300 Voices.

I would like to know if you have the same problem.

Best Regards

Jack

Ok, let's work through your list:

  • Sorry... can't help with that, I don't have a DB60XG
    Presume you mean a rotary encoder to control the device... again, not my design goal, so can't help. I'm sure it wouldn't be too difficult to implement though, and the mistralXG code is available (for personal use).
    Hmm.. that would be nice, but it's not something I plan on doing any time soon as I don't have a bigger display, nor the need.
    This is in my plans... I've incorporated memory into the design since the publication in Nuts & Volts (the new schematic isn't up there yet, but I'll put it on my site sometime). Now the hardware is finished, my immediate plans are to migrate to a later version of the Microchip USB framework and then add code to load patches from memory. My spare time is getting less rather than more, so it may be some time.


    I tried three files from the site by Trond (Dune Mood.mid, Garbage Can.mid, Jumper.mid) and they all sounded fine to me.

    Regards, Steve.

Awsome design! I wish I had the know how to make my own custom boards. Would you maybe do a pcb bulk run for us midi boxers? I still have to read through the article but are you editing sounds with cc messages? Any sound samples?

Thanks for the compliment.

I'd consider getting some PCBs made if there was enough interest.

Basically, you have full access to the DB50XG... you can send CC, Sysex, whatever you like. I don't have anything recorded at present, but it's an idea... I may put something up there when I get some time.

Steve.

I have also a sound sample from the Yamaha Demo xg midi file (Jimi Hendrix - Voodoo Chile), but I don't know if it cause a copyright problem.  ???

I've played that through mistralXG... now that is some great sequencing and sounds fantastic. I've also got a tremendous version of Birdland (Weather Report)... I have the same concern about copyright, however.

Steve.

Stever,

What is the 128kb Storage used for? I read through the articles a few times, but i couldn't find much info about it.
