MTG R100 Builder – Kawai R100/R50 EPROM Builder Software

This software will enable you to create your own custom EPROMs (BIN files) for the Kawai R100 or R50/R50e legendary 12-bit drum machine/rhythm composers.

In a nutshell you collect/create a bunch of WAV files, one for each of the 24 instruments and then this software compiles and converts them into the compressed Kawai format. It’s been a pretty big undertaking, starting with the dissection of the Kawai ASICs.  I will eventually include a User Manual and a bunch of WAV and BIN files to get you started.

Your WAV files should each be:

  • Mono (1 track)
  • Sample rate of 31.25kHz (you can resample easily in Audacity or similar)
  • 16-bit linear PCM (standard WAV)
  • Should fit within the sample space of the pad you are targeting.

Kawai R100 Builder

The look and feel of the software is based on the HR16 Editor by Dustin Licis. You can save file sets as a project to save time in the future.

Why bend and mutilate a fine instrument when you can bit-crush samples and add them to your kit? My EPROM Switcher boards will be available again Jan 1, 2014. Watch my eBay page.

Email me if you want to try it. It’s pre-release at this time.

    I’m stupid excited about this. Thanks for putting it together! I’ll definitely be buying a couple boards from you. Unfortunately I’m a Mac user though :/ I don’t expect a Mac version of the software but it would be awesome if you could post a thorough how-to for those of us who are Windows ignorant delving into Parallels, et al. My main question is (and has always been): What EPROM burner do I need to burn the custom chips? And which chips?

    Anyway, really looking forward to playing around with this. The R-100 is king of vintage digital drum boxes in my opinion. Custom ROMs will take it to a whole new level. Thanks.

    Hi,

    I am a follower of your blog as well (and a JX3p user too). I don’t have any Mac experience, but I have at least one guy in Sweden using the software on a Mac so I know it works. You will probably have to ask some Mac people for help there.

    The preferred chip is 27C400 though I think there are other chips that are equivalent but as I’ve never used them I’ll refrain from mentioning their names for now. They are made by ST Micro, AMD and others. So that would be what you would look for in a burner. I have two burners, Galep-5 by Conitec and a SuperPro-600P. The Galep is a nightmare on Windows8 so that’s why I bought the Xeltek. There are definitely cheaper models as those are each about $600USD.

    And I have one board on eBay at the moment, and more to follow after Jan. 1, 2014.

    hey man,
    I’d love to burn some sounds for my kawai.
    I use a TOP853 eprom programmer. so i can just burn bin files to eproms an et voila?
    let me know
    cheers

    Assuming the programmer will program the EPROMs you buy, then yes! I use AMD 27C400′s but there are some other names/numbers for this format as well. The 27C400 is 4 Mbit (512Kb x8 or 256Kb x16 selectable by one pin) and the Kawai R-50/R-100 use the 256k x 16 arrangement. Just check the pinout versus the 27C400 and you should be OK.

    The Builder software download is free so you can try it for no cost. The version I ship with my expander board has a few minor improvements over the free one, but you should be good to go either way.

    Hi, maybe i am blind but i don’t see link for software download, plase write post or mail me. I just want try it, thanks much for reply.

    The free software is here: http://musictechnologiesgroup.com/files/R100BuilderFree_v0_20.zip

    The software that comes with the expansion board has a few minor updates since then.

    Hi

    The HR16 Editor by Dustin Licis you mention, is that on the web somewere? I can’t find it.

    Thanks

  8. OLLE says:

    I will buy you R100 3 eprom exp. soon by the way , just need to find an R100

    I think there are at least three editors now for the HR16B. The one I looked at, but never really got a chance to use was Dustin’s. I heard about it on GearSlutz.com and there is a link in that thread. I copied it here for you:

    http://www.mediafire.com/download/tdddsm1qd67a4sd/HR16B_EPROM_Editor_Setup.msi

    There is also a new one and another old one. I think both of these are mentioned on Burnkit2600.com, although maybe they only mention the old one.

  10. grantb4 says:

    They are up on eBay all the time. I got mine off Craigslist locally for $50! There were a few minor issues with it.

    My Pro One was only $300 but I had to drive a way into the countryside to get it and it needed some repairs. Also through Craigslist.
