  1. Monome x Arcade Buttons Midibox

    in MIDIbox of the Week

    Posted

    @slubgud, sure sure, here's the Max/Msp program you need running to make the midi Monome compatible

    Credit for the original program goes to this guy; however, his only dealt with Midi in. I added functionality to convert the out to midi and send it to the controller.

    http://docs.monome.org/doku.php?id=app:midi_monome

    I'm simply using the standard MidiIO128 mapping with the button feedback turned off. Every button is mapped to a midi note and the corresponding led is the same midi note (note number 48 up to 111).

    @slumgud, the buttons are genuine happ push buttons and i purchased from lizardlick:

    Note that, you pretty much can only get away with illuminating the white push buttons with a really strong LED. They sell opaque and transparent buttons but they are usually like a dollar more. I drill a small hole at the bottom of the button underneath the actual switch that fits the LED nice and snugly.

    Thanks all, and @ToS yes, you noticed my attempt to clean wiring! Everything is harness based. So much easier, just takes some time to plan out.

  2. Monome x Arcade Buttons Midibox

    in MIDIbox of the Week

    Posted

    Monome x Arcade Buttons all finished! My goal for this project was to be compatible with existing Monome programs and utilize big, fun to press, arcade buttons. For Monome compatibility I'm using a custom midi->osc converter running in Max/Msp. As long as it's running, any Monome 64h program works with my matrix. Theoretically there are some bandwidth problems using midi but I haven't run into any issues with the programs I've been using. On the midibox front, I got 1 CORE, 2 DINS, and 2 DOUTS.

  3. MidiboxSID all finished with custom bamboo Panels! (Pics)

    Here are some pictures of my finished Midibox SID V2. Finally got around to finishing everything up this weekend. The panels turned out great (laser cut bamboo) and it's sounding awesome! Thanks for all the help! My next project is a 64 in 64 out matrix, yay. Got all the parts just needa find the time.

  7. MBSIDV2 Editor Exception, Mac

    in MIDIbox SID

    Posted

    Been trying to figure this one out for a while with no luck. I am using a Mac to run the MBSIDV2 Editor. I initially was able to run the program fine and it was awesome! A few days later, I tried to run the program and I get the following exception. I am using a M-Audio 2x2 and I have mmj installed.

    Exception in thread "main" java.lang.NullPointerException

    I've tried restarting, unplugging the midi, deleting the MBSIDV2 files and re downloading them. No luck... Any ideas?

    Just really excited about this one and wanted to thank every one for the amazing amount of information on these forums. After many many problems I finally was able to upload the Midibox SID app and get sound out of my 6582!! The last problem I faced was a non functioning octocoupler that wasn't sending the midi in signal to the core chip. Took me a while to figure that one out but I just got the replacement chips in the mail yesterday, plugged a new one in and everything worked! First time I turned it on I got a horrible noise. Turns out I had my audio out backwards. Fixed that and then turned it on again... the most beautiful synth lead sound I've ever heard.

    Now on to making my control surface and faceplate, I'll post pictures of my progress so far later tonight!

  9. Optimised Power Supply

    in MIDIbox SID

    Posted

    Not sure if this helps you too much but I just built my optimized power supply. Everything is working quite nicely on mine! I ordered everything from Mouser in one order and this is my part list:

    1 80-C322C334M5U7301 50volts 0.33uF 20% 08/27/08 2 0.670 1.34

    2 140-50U5-104M-RC 50V .1uF Y5U 08/27/08 2 0.220 0.44

    3 821-TS7809CZ 3-Terminal Fixed 08/27/08 1 0.370 0.37

    4 647-UKT1E222MHD 25volt 2200uF 20% 08/27/08 1 1.130 1.13

    // Note here you are gonna want to order the 16volt cap as well, I already had one

    5 625-W08G-E4 1.5 Amp 800 Volt 08/27/08 1 0.520 0.52

    6 625-KBP01M-E4 1.5 Amp 100 Volt 08/27/08 1 0.580 0.58

    7 625-DF02MA-E3 1.0 Amp 200 Volt 08/27/08 1 0.380

    Notice I ordered a three different bridge rectifiers. I ended up using the first one (number 5) but they should all work. 

    I also needed:

    - A prototype board to put all this on

    - Reused commodore psu connector, switch, and led

    - Some pin headers so you can easily connect your psu to you core and sid

  10. C64 Power Supply Connector

    in MIDIbox SID

    Posted

    That looks perfect! Should be wiki'd on an Optimised PSU page if one exists.

    I got this connector about a week ago and it is perfect! The pin layout is a little different from the commodore 64's (just look at the spec to figure out the numbers of each pin) but it is pretty much the exact same size and fits the commodore case perfectly. Highly recommend! I bought the other connector too and it fits the power supply properly. If you are making your own case this one might be better since you could bolt it on easily. 

  12. C64 Power Supply Connector

    in MIDIbox SID

    Posted

    Hello! I looked all over the forums for an answer to this question and couldn't find one. Appologies if this has already been discussed.  ;)

    I'm looking into buying a commodore 64 power supply but just the power supply and not a C64 system. Thus, I would not have the PSU connector and the power switch panel for the optimized power supply solution. Is there anywhere I can buy a compatible connector? Should I just give in and buy a system? I suppose I could also just wire directly to the power supply without the connector but I would rather have it removable.

    Thanks a lot and also let me add that these forums have been amazingly helpful in building my Midisid!!
