  1. A commercial SID synth that look damn familiar (seen on MESSE)

    in MIDIbox SID

    Posted

    Hello,

    I designed this and it ain't a midibox. I have already made a couple of those in the past ( both were midibox SID of the week, search "alkex sid") and wanted to build something different.

    This was initially a self-challenge to build a sid synth with more of a groove-box approach, focused around composing beats and patterns.

    All the instrument patches are crafted in software.

    Here's a video of the wavetable editor:

    This machine is AVR based and coded from the ground up, datasheet in hand as a fun challenge.

    I have a boatload of respect for TK and have always played by the midibox rules but I'm now grateful to have met Michael from Mode Machines in spite of the history with midi-box (which I was well aware of).

    He, his team and other developers I've had the pleasure to meet via him are great creative people that I am proud to associate with.

    Now you know :)

    I love both my midibox sids and the groovebox, they each serve different purposes and live happily in harmony in the studio.

    Best wishes from the dark side!

    6x Smash TV PIC 452 loaded with MIOS

    2x PIC 452 virgin

    7x 10 MHZ Xtal

    1x Stuffed Din

    1x Stuffed Ain

    5x Stuffed Core8

    One Sid Module stuffed ( No Sid Chip!!!)

    8x Brand new AIN_R4 PCB (by smash tv)

    2x Brand new DIN_R5 PCB (by smash tv)

    3x Brand new CORE_R4D PCB (by smash tv)

    1x Brand new SID_R3A PCB (by smash tv)

    1x Breadboard ain

    1x Stuffed Aout

    All boards are working to my knowledge since they were removed from working projects. However a Wires might have come loose.

    I'll throw in a handful of random knobs if I can remember where they are hiding...

    I was hoping to sell it as a lot but I'll split if necessary

    Make your offer!

  8. MIDIbox of the Week: MIDIbox Minimoog by Alkex

    in MIDIbox of the Week

    Posted

    Hi All

    I just finished my minimoog controller and thought I'd share it with you!

    20245_291594571564_607621564_4577129_75624_n.jpg

    Features:

    Simple design: Used 1 core and 2 breadboard ain modules.

    Bus powered USB: I took a cheap usb/midi cable (ebay) and hard-wired the midi input and 5v from the usb port directly to the core.

    Dimensions: Front panel is considerable smaller than the original minimoog (designed to sit over my MB SID keyboard)

    Front panel: 100% front panel designer

    switches: Cheapo rocker switches spray painted and wired as pots (to save the hassle of building a DIN Module )

    I don't have photos of the inside but you can see it's ugly guts in this video:

  10. Midibox sid - keyboard "woody" upgrade

    in MIDIbox SID

    Posted

    analogue_mo, it's quite doable.

    This was my first dabble at woodworking and I found it to be quite easy.

    I had already sanded body filler on my car and found the wood much nicer and easier to shape.

    and Wilba, thanks for the Sids they sound Great!  ;)

    Now to somehow make space on the panel for a IN to OUT  feedback pot...  ???

  12. Midibox sid - keyboard "woody" upgrade

    in MIDIbox SID

    Posted

    :)

    Thanks again for your kind words!

    The keyboard if from an old ELKA synth. I rewired it's keypads to a DIN module on a separate core which sends the midi to the SID core.

    Here are a few videos of the process:

    Debugging the midi keyboard:

    <object width="560" height="340"><param name="movie" value="

    name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="
    type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="560" height="340"></embed></object>

    I accidently switched a couple wires on the DIN PINS so had to write a routine to correct it (easier than rewiring everything)

    Staining the wood in my best shirt... Not recommended

    And finally

    The inside is pretty much the same mess and the images Smithy kindly linked us to above except i recently discovered the wonders of cable ties. Great to identify loose wires when tied in little bunches at the ports...

    I Hope this inspires anybody for a wood design!

    Cheers

    Ps: puddingbrumsel, the bottom right says Smith it's my signature  - works in the ego department :)

  17. Adding 6x7 button matrix to midibox sid with cs

    in MIDIbox SID

    Posted

    Hi again!

    Here is the FPD for my midibox. Have fun!

    keep an eye out for my next project - installing this stuffed ASM2 http://www.elby-designs.com/asm-2/asm2.htm mainboard inside this moog rogue shell.

    vcos vcas and vcfs will be modulated by MIOS_SID software via AOUT_NG. I'll design a faceplate as close as possible to the sid CS and try to benefit from all the cool features this CS has to offer (presets - mod matrix - lfos env etc)

    the most challenging will be to stuff all that including bipolar psu in the case but it should fit with a little hacking.

    I'm very excited about combining of the SID CS with this analog modular.

  19. Adding 6x7 button matrix to midibox sid with cs

    in MIDIbox SID

    Posted

    Hey All!

    Thanks for the help. It does indeed make sense to have a separate core in there just for keys.

    I actually used Thorsten's design rather than Matrix but the front panel is clearly based on Wilba's design

    Here is a porn shot of the thing (not as nice as the outside) :

    3208_95801996564_607621564_2594711_6020810_n.jpg

    Bontempi sure rock! I love their toys - This one in particullar! It was allready stuffed with midi sockets, a nice power supply etc and the keyboard matrix is ready to hookup out of the box!

    I designed the FDP on my pc laptop that I gave away but I should have it on Hdd somewhere. I'll be sure to post it if it shows up.

  20. Adding 6x7 button matrix to midibox sid with cs

    in MIDIbox SID

    Posted

    Hi All

    i finally got around to building another all in one midibox sid since the tragic loss of my first bondo based edition that fedex broke (rest in pieces)  :P

    3208_95475206564_607621564_2588531_1494225_n.jpg

    3208_95475211564_607621564_2588532_2264167_n.jpg

    3208_95475216564_607621564_2588533_5435236_n.jpg

    I built the front panel into an old bontempi organ that is really nice and heavy.

    I have one core driving 2 sid modules and would like to hook the 37 keys to it.

    I guess the logical path would be to put them on a 6x7 matrix but:

    Here's my question: Will the core handle the extra button matrix instructions in a reliable way or should I consider building a dedicated midibox for the keys.

    Thanks in advance for your advice!

  23. spitting j5 into 4 out / 4 Ain

    in Design Concepts

    Posted

    Hi,

    I'm using a midibox cv to midify a Moog rogue but would love to convert the synth's cv out into midi using an analog input.

    Right now, I am usgin port J5 as Dout for trigger but only need the first 2 pins as outputs.

    Is it easy to redefine say pins 3 to 8 of J5 as analog inputs?

    Thanks in advance for your insight

    Best regards

    Alex

    I've been very busy with my new job and have unfortunately been away from midiboxing for a while so I might be forgetting something stupid.

    Thanks for any advice

    Best regards

    Ps: be on the lookout for my latest all in one Sid keyboard I'm building to replace the one Fedex broke, it's gonna be a killer ;)
