  1. I don't know whats up with the gideon fpgasid, maybe this project is frozen meanwhile because the "other" fpgasid is out.

    You have to take a look sometimes at the ordering page for the swinsid ultimate, this c64 products are sold out from time to time but the chance is good that they get back in stock because they mostly produce small stacks.

    The swinsid is useful but sounds boring after a while. There is an alternative firmware for mbox sid with higher parameter spectrum http://www.swinkels.tvtom.pl/swinsid/ but have not tested this one (did not know that)

     

    Follow the link to armsid there is a link to an order page, there you get audio-demos https://retrocomp.cz/produkt?id=2

    There you can hear much of em...

    There is also an arm2sid, a double sid and it does also fm. https://retrocomp.cz/produkt?id=20

    It's an emulation of this (OPL2) FM Chip https://en.wikipedia.org/wiki/Yamaha_YM3812

    I guess it would be possible to use this with a mbox sid but it sure needs some adjusting. Maybe it's possible to put an alternative firmware inside a slave core. But, no, I don't think so because you would have the same parameter Menu than the Master. By the way, the MBox FM uses an OPL3. 

     

    What's fine about these chips is the possibility to build some custom design with an exclusive sound but for this you need the know how (I don't have)

    Also, if you would build an alternative chip you would need to modify the mbox sid software.

    All of those listed sid clones have some pros and cons but sound very similar cause they are designed for the c64 community as replacements.

  2. Because SID Clones are cool and from time to time a new one appear, this List could be helpful to get an overview.

    Feel free to add new or further Information where to buy/whatever... (Technically they are no real Clones they are emulations on microchips)

    Dual 6581 SID Emulator (DIY)

    Teensy 3.5 (ARM Cortex M4) + PCBs (no good Plug and Play for MBoxes, look at the Dimensions)
    Code is based on ReSID Engine which is the Soundengine of the VICE C64 Emulator
    Infos: https://hackaday.io/project/159917-dual-6581-sid-emulator

    It is possible/necessary to configure SwinSID Ultimate, FPGA and ARMSID (6581/8580 mode, Filter mode) you need a working C64 for this and a sd2iec or something similar. Keep that in mind. Read with which configuration they will be shipped and may ask the seller if he can configure it to fit your needs.

    ARMSID offers a standalone and DIY Arduino based solution to configure ARMSIDs without a C64 https://retrocomp.cz/produkt?id=67

  3. Every Core (socket) is sharing the Midi IN "lane", so if every PIC has got it's own ID, you can communicate directly via MIOS Studio with every PIC by ID.

    But 

    Midi OUT is set by J11 to get feedback from MIOS Studio

    (Questions and Answers)

    Next Question,

    How to Clone and why?

    You don't need to because you must upload MIOS anyway. So it's just one step less. (Someone should correct me because I'm not 100% sure about that but I explain why) The cloning function is just for updates or to clone setupmb6582 to all slaves. (and this is ok if you just use 8580/6582 SIDs)

    For better understanding:

    the setupmb6582 is the firmware for the Master Core (Operating Software)

    but if you use some 6581 in slave 1, than you should choose setup-6581 for this core.

    If you clone (hold menu down by startup) every core uses the 8580/6582 firmware (which has a different filter table than 6581)

  4. Ah, no.

    As I said, you don't need to compile. You digged to deep. It's good for your knowledge but not in the case do get the stuff running immediatly.

    First, flash Bootloader with PicKit Programmer (IPE not IDE should be inside the pack with the IDE, however by google I just get this result) if you can handle it with IDE, never mind. But you just need the easy IPE with which you can load hex files.)

    bootloader_v1_2b_pic18f4685.hex, right

    First choose device Family 18fxxxx

    I don't really know if there is a way to give ids, I think its in the hex and default 00 

    Than

    open MIOS, connect to your PIC via Midi, error message, right

    load mios8_v1_9h_pic18f4685.hex

    Should upload after some seconds, if not, turn power off and on

    Should upload

    Than

    you get no error message, MIOS recognized or something

    upload setupmb6582.hex or however it's called correctly

    do this with every PIC and change their ids 

     

    No problem to ask, I also had and will have this times where I'm stuck or don't understand correctly.

    Would that be it tho? #9 on the next page lists the supply voltage for the backlight at 5v. So I should still be able to see the backlight?

    I'm not sure. 

    Look at the page you linked to, there is a rating of 5.5v.

    By google-ing MC42005A12W I found two pages where supply voltage is = 6,5v

    (https://circuitmaker.com/Components/Details/CEB71AC3-FCA9-468A-B8B6-F2F812995F36)

    and you could read this thread:

    but not even a backlight. 
     

    If you don't even have a backlight than it is difficult to see something.

    Mostly the last Pins at the Display are for Backlight, you can put 5v and - at the pins and backlight should work. If not so, it's dead.

    Than you have those trimmers for Backlight and Contrast, have you turned them?

    Maybe you need a negative Voltage for the BL, this is often the case but I don't know.

  7. I also had problems with CTRLR in the past, but I did not use it much. I remind that the problem with live was that it don't send the midi out because live "thinks" it is a vst sending audio out and I couldn't figured out how to solve this. 

    Using an older Version of CTRLR was also a thought of mine having other problems. I still don't know if this would help in some cases but that is why I build Control Surfaces to my Midibox Synths, to be independent from software which could be obsolet and unsupported.

    What you can do is to send a lot of CCs with live which is supported (I think) I don't use live. This is the chart for CCs https://github.com/midibox/mios8/blob/master/apps/synthesizers/midibox_sid_v2/doc/mbsidv2_cc_chart.txt

    However, it looks complicated, I can't explain it exactly to you because I have no big experience. 

    I have a VST which I need to search because it isn't online anymore, I can upload this.

    But I recommend you to build a Control Surface not only because it is really great (TYVM Thorsten) it offers also some really cool features, like wavetable editing and Sequencer and you just don't recognize it if you haven't built one.

    (1 LCD, 2xDinX and a Bankstick is the simplest Version)
