    Nils made a standalone patch editor called Patch Turkey which currently supports the Lead Engine only,

    but while searching keywords to find a link to it, the only place i found it on,

    was in the Synthedit Yahoo User group of all places!!! WTF?

    Its attached to the 2nd post in the topic, it really should be publicized more as its such a sweet editor.

    Mebbé i add a wikkeh page soon.

  7. FPGA SID with Filter Emulation (+ Pokey + NES)*

    in MIDIbox SID

    Posted · Edited by Smithy

    Mebbé old news for some, mebbé not so old news for other hoomans like me.

    Video is almost 2 years old nao:

    Copied from CSDb.org 02/04/2008:

    "Kevin Horton, the hardware hacker extraordinaire (mostly known from his game console hacking) is working on a SID implementation in FPGA.

    Yes, it has been done before in eg. C64 DTV (which doesn't even emulate filters), but his aim is to make the filters sound *very* exact to the real thing, by actually implementing them OUTSIDE of the FPGA as a discrete circuit! It is described in greater detail (with samples!) on his blog, at http://blog.kevtris.org/

    The filter circuit is based on the actual SID die, as imaged by Tim Boscke (http://www.digital-circuits.org/sid/).

    Kevin is looking for all kinds of info about different kinds/revisions of SID chips, and also SID musicians with good ears to assist in filter tuning. Actually, all kinds of help and information would be appreciated. Recordings from additional real SID chips of the 'trickier' songs which use the filter would also be much appreciated.

    Another thing which might be of interest for you other hackers out there in regards to his game console hacking, earlier SID player(s), and other FPGA work: http://www.tripoint.org/kevtris/index.html

    He can be contacted at kevtris[at]comcast.nospam.net

    Toni Paavola and Jonathan Gevaryahu on behalf of Kevin Horton"

  9. Mixing and matching SIDs?

    Found a thread on it, seems it worked for other people too Rosch, but the filters can sound weird.

    I wonder if you could use different capacitor values to get it to sound closer:

    http://noname.c64.org/csdb/forums/index.php?roomid=7&topicid=2096

    "But beware: One chip cost's US$25, excluding shipping, you get 3 C64s on the local fleamarket for the same money."

    AHHHH, the good oul days when sids were as cheap as chips!

  12. Mixing and matching SIDs?

    in MIDIbox SID

    I was under the impression that it is not easily possible to mix the 6581 and the 8580/6582 in the Sammich. There are a number of jumpers which set the overall power to 9V or 12V.

    Yep, this is correct.

    From the sammichSID manual:

    SID Voltage Jumpers

    The L-shaped header JP controls the voltage supplied to both SIDs. It will supply both SIDs with power

    from either the regulated 9V supply on the base PCB (i.e. directly from the 7809 voltage regulator) or

    from the input power supply which must be regulated 12V DC.

    So basically you cant use a 6581 and an 8580 together, if you set the voltage to 12V, the 8580 will blow.

    Has any actually tried supplying 9V to a 6581?

    I wonder if it would make any sound at all, probably not.

    The power supply is the one seen in the video is from an old external disk or something, me and 12 Vdc 5Vdc supply and stabilized (no use 78xx), we do not feel noise. My idea is to mount MIDIbox SID in that cabinet.Thanks!

    Well if it hasn't blown up your sid yet, then it should be fine! ;)

    It might be safer to use a 78xx though, just in case the voltage fluctuates.

    3 patches are hardly worth it. I'll upload it in due time. Patience is a virtue ;)

    so i can't upload teh whole TWO patches i madez,

    neither can I download all the new patches in the sticky, but I'm really looking forward to trying them out! :rofl:

  19. Yet another MB6582 lives

    The LCD is from this guy from Poland on Ebay.

    Heh, just stocked up on SIL/DIL Headers, and connectors from this guy, his prices are the cheapest i've seen.

    Almost tempted to buy the red/orange 4x20 LCD as a spare, but i already have 2 black on green as spares!

    He also sells, a set of angled SIL headers, connectors and crimps.

    Ill be using this kit to connect the cables on the CS PCB:

    http://cgi.ebay.ie/5x-Connector-crimp-Header-PIN-1x8angle-8crimp-complet-/170422616083

    9fba_1.JPG?set_id=800005007

    If the plastic is too wide on that right angled SIL header, you can order the kind Hawkeye used:

    341846706-40.jpg

    I'll be crimping the crimps to the ends of these cables, which I'm currently using on the Base Board side:

    http://www.reichelt.de/Platinen-Steckverbinder/PS-25-8G-BR/index.html?;ACTION=3;LA=2;ARTICLE=32346

    PS25_8.jpg

    The height of those connectors is about half the size of the normal white connectors,

    which is essential due to the lack of space in the PT-10.

    The end result will be a combination of what i'm currently using and what Hawkeye used.

    Its probably the best completely detachable solution.
