  4. MIDIbox SID manual in PDF?

    in MIDIbox SID

    Posted

    Does such a thing exist? Could it be created without too much trouble? I understand the utility of keeping it online, such that it can be updated along with the software, but at the same time, having seen my fair share of websites disappear from the web without notice or reason, it'd be nice to have a local copy for my own records. Doubt that MIDIbox is going anywhere soon, but all the same...

  9. SID chip filter distorting/clipping?

    in MIDIbox SID

    Posted

    Ok found the issue. sammichSID is not at fault, thank goodness. For some reason a bunch of garbage CC data got recorded into my sequence somehow. Thanks for the help; even if it was just helping me rule out my hardware as the issue! The CC causing my issue was 22, which controls waveforms. Turns out there's a bunch of CC garbage on a lot of others too, just none that affecting the sound in this sequence on this patch. At least I got to open up my sammich again!

  10. SID chip filter distorting/clipping?

    Can't seem to duplicate the results noodling on a midi controller, which I suppose is comforting. I have no idea what's going on in this midi sequence that's causing the sammichSID to bug out though. I tried deleting the notes and adding them back; I tried changing the note value, I tried changing velocity. I hit the same notes elsewhere in the sequence with no problem. Grumble,

  11. SID chip filter distorting/clipping?

    All filter caps remain in place; I gave them a good little shove for good measure (and terrifyingly bent one over; seems fine though). Hmmmm... Now I seem to be getting the same clipping and distortion without the filter engaged. Always seems to be at the same two points in my MIDI sequence, although I can't understand why; there's nothing special about those notes that I can see. More investigation is necessary.

  12. SID chip filter distorting/clipping?

    I was running my sammichSID through some midi today and noticed that patches involving the filter seemed to introduce significant clipping/distortion.

    I haven't done extensive testing, but it seems to happen at least with the LP filter, especially when the cutoff is turned down. Changing the patch to something else and then back seems to help for like five seconds. I am not even sure how to begin more extensive testing, any advice regarding that is appreciated.

    I just underwent a move that involved shipping the sammichSID; I could believe that some damage was done. It just seems odd that both SID chips would undergo the exact same damage at the same time. As far as I know, the filters were fine before the move. Both chips are 8580 btw.

    Am I missing something?

  13. Ctrlr based editor for MBSID V2

    in MIDIbox SID

    Posted

    ctrlr doesn't seem to run on OSX 10.5.8, which is what my current computer is running. No other options for controlling an MB SID, short of putting together one myself, I'm guessing? Maybe I'll have to just bite the bullet and update the OS on this thing, although what I really want is a new laptop.

  14. Starting my second SID project

    in MIDIbox SID

    Posted

    It doesn't seem like SmashTV has a 2-SID-socket board, so I'm planning to order the 6582 boards, which I already know how to put together. The top board won't fit a C64-case front panel (i suppose), but we're thinking of actually cutting out the top board and place them where they need to be to fit the front panel.

    We'll order the boards only - not the parts list since these can be found here in Scandinavia.

    Would it be enough to order one preburned PIC since we're only going to use 2 SIDs?

    Each SID module holds a single SID. You just need two SID modules for a stereo setup.

    I do not understand what this fuss is about - here are the links to a previous fleamarket offerers asking 400 euros for theirs sammichSID's:   http://midibox.org/forums/topic/18138-soldsammichSID-for-sale-with-2-6582/'>http://midibox.org/forums/topic/18138-soldsammichSID-for-sale-with-2-6582/ http://midibox.org/forums/topic/17650-sold-sammichSID/'>http://midibox.org/forums/topic/17650-sold-sammichSID/ http://midibox.org/forums/topic/17628-sold-sammichSID-for-sale/'>http://midibox.org/forums/topic/17628-sold-sammichSID-for-sale/ http://midibox.org/forums/topic/17961-for-sale-sammichSID/'>http://midibox.org/forums/topic/17961-for-sale-sammichSID/     I don't want to earn anything here - I just want to regain invested cash, I've payed a lot of money to a professional soldering company and SID modules.
    No fuss, just curious about TK's take on sammichSID prices.

    Isn't there something in the MIDIbox license about profiting from the sale of MIDIbox hardware? It's hard to quantify how much value the physical construction of a sammichSID adds to the total cost, but I think increasing the price based on rarity would be pretty clearly out of bounds. That said, I've definitely seen sammichSIDs sell for considerable amounts in other places.... Interested to hear TK's take on this. Looked it up: "Products may only be made for your personal use or for distribution on a non-profit basis (e.g., sold for no more than the actual cost of components, assembly, and shipping)"

  19. sammichSID Midi Setup Question

    in MIDIbox SID

    Posted

    I attempted this little MIDI Thru tweak. Got the new sammichSID .hex file compiled alright and uploaded the new firmware to my sammich without apparent problem. The sammich works fine and passes MIDI as I had hoped.

     

    There is one thing I wanted to check. After installing the new firmware, MIOS Studio gives the following error message:

     

    Detected MIOS8 and MIOS32 response - selection not supported yet!

    Check MIDI IN/OUT connections

    and Device ID!

     

    I'm guessing it's because when MIOS Studio sends out a query, it doesn't expect to receive that query back (seeing as how it's actually hooked up to a MIDI Thru). If so, I suspect the error message is the expected behavior here, no? If so, is it going to cause me problems if I ever try to upload another .hex file; could I simply unplug the MIDI Thru cable?

  20. need information on the sid chips

    ^the sammichSID takes a 12v power supply no matter what chip is in it, and there's no need to change voltage regulators. Everything is changed on the inside with jumpers: either the 6581s take power directly from the supply, or the 8580s take it from the regulator. Other than that. It's just a matter of switching the capacitors for the filter.

    It'll be really tough to fit the modular boards into a sammich-sized case, but I'm sure you could get something pretty tiny if you don't mind doing the work for a custom case.

    The build guide on the wiki is pretty straightforward. The advantage to doing a modular is that you can always expand the number of SID chips or fill out the control surface as needed.

    Unfortunately, the sammichSID was a limited-run kit. All the sammichSIDs that were made have been sold and as far as I know, there are no plans to produce any more (although you never know)... If you already have your SID chips and want to build a synthesizer, you're probably going to have to go the modular route. It's a little daunting, but not impossible.
