Yea it's awesome, excellent build! :thumbsup: So much better than using DOS trackers on the ole SBPro2. I've wanted something like this since I was a kid. Only thing I wish was some sort of hardsid type setup to use it with dosbox, but ah well emulation works well enough for that now.

https://soundcloud.com/televicious No longer No Plan E.T. Now Televicious. Half this stuff is Adlib Tracker 2 and SID Wizard with DualSID 8580's. The rest is Midibox SID V2 with 2 6581R4's and a sammichFM I acquired from the flea market here. Thanks again Kristal! Back to midiboxing after a long lunge at native trackers for the machines. Tracking is great, but these midiboxes have a lot of power. Working on building filter boards and an AOUT for the Sammich next.

The Hardsid.dll crashes all over the place, I found asidxp works great so I was curious about your asid tracker. Any reccomendations? I'd just like a functional tracker built specifically for SID. Preferably running on any modern OS.

Are you guys playing in Austin anytime soon?

Just curious if anyone's tried programming a 36 op mode application.

Just curious if anyone's tried programming a 36 op mode application.

It WORKS! In "stereo" and fully navigable. Damn New tech lcd's would have been cool, but function beats aesthetics. Thanks all.

I have that set except the bit that I'm using a 12V 1A DC, since no C64 power supply. No ribbons cables being used just straight wire soldered from one hole to another. One at a time. I have the 12V lines running directly to the SIDs J1 and Core J1, the core has a Vreg to burn it down to 5V the SIDs don't need it, everything else is just as is as the schematic except I have the 5V Vs and Vc connected. Maybe the panning issues have to do with my output wiring. I just attached the +'s to each channel and the -'s to the ground on the 1/4 inch jack. Also, jumpering J4 doesn't do anything. I will try detaching the 5V Vs and Vc from the core and see if that helps. I saw in other posts people were successful with running just 12V lines to the J1 for power needs. Also, for more info on my LCD issue http://www.mouser.com/catalog/specsheets/UMSH-3267MD-UB.pdf this is my LCD data sheet. It doesn't make use of the contrast pots or anything the display has its own brightness switches. Everything works fine on the first line of the display. The second line was displaying some garbage when I had it even more miswired a few months ago. I don't understand where the 1K resistor from the core's D3 is supposed to route to. Is it supposed to route to J2? oops just had to lurk moar Anyhow didn't help the situation. :( Maybe I need to get a different/new LCD? Also, I changed cursor position from 0x40 to 0x20 on line two in the setup_6581.asm and still nothing. I think the data sheet implies that it only operates in 8-bit mode. that must be my problem. time to get a new Lcd. :/

so i did a j14 to one the other is connected to the normal SO spot and they both are working on the left channel but panned to the right go silent. Doesn't seem correct. also so looked up 4-bit lcd 1k resistor CAN setup with 4 empty data spots? I'm guessing the CAN with 1k resistor is for the optional CAN bus and not necessary so I'll snip the 4 data wires see if that don't fix it. Did nothing at all.

Ahhhh thank you j14 to so. Will look into 4 bit

So I figured I'd save up and lump my troubles in case they're linked. Firstly, the LCD only shows characters on the top row. All connections tested fine. Triple checked connection routes. Second, stereo Sid off one core. I rigged the wires to go to both Sid modules in the same fashion and have them outputting to the left and right channels. How does the core determine left and right? Third, filters appear to be working to some extent. They're the 6581s and I have 12V power running directly to each module, but most 6581 patches are dead silent. I kind of expected this getting these, but if anyone know a trick to get the filters fully functional I am all ears. They work slightly better since I took the vregs off. Fourth, my 8 banksticks appear as 1. It kept formatting and restarting without formatting for about an hour and a half before resuming normal function. Lastly, the select buttons appear to work judging from the top row of the offs functionality. But parameters don't appear to be editing at all.

Oh holy crap that makes so much sense. That's probably the issue. I bet I will owe you a drink now. Thanks man.

Ahh, thank you. I'll work it out I just needed to know whether to build up or down to get past this. back to the basics it is. I'm guessing it's trouble with the DINs which is hard to believe as they're so simple.

I've built 2 of the DIN R5's and setup buttons and an encoder for the first couple of registers on the board and uploaded the .hex with default .asm which I made sure matches the few bits I'm trying to get to work. The few parts that are on the boards are definitely all situated in the correct spots. Neither DIN works. I multimetered all the wires and the signals are actually going through. I also found by bumping the core connections with the multimeter I can navigate MIOS very haphazardly, but not with the buttons or an encoder or anything. The DIN is connected to J9 as it should. Does the entire control surface need to be built for the basic buttons to work or are my electronics just giving me the cold shoulder?

Howdy, almost at the halfway point with the Step C build, but I noticed mikes shop doesn't work where I am and there seems to be no bankstick prefab PCBs anywhere. Is everyone just making them out of blank boards and soldering the wiring to IC sockets or what is the recommended method of build? I couldn't find any other topics on this specific thing.

Oh I meant it has square saw and triangle for each oscillator. For some reason there are solder patch points on the back for these things. I'm guessing so you can switch between them on each oscillator. Really curious about what korg's idea for modding was by putting this stuff on here. pretty amazing no ones managed to figure this out and it's been out since november 2011. I went and got the monotron Delay and midi modded that, think I have to pinch a resistor off still as the keyboard control seems really haphazard on that. the whole range/scale of notes is on only 5 keys playing 5 octaves. I'm pretty certain the midi-if kit won't work with the duo.

Been looking for schematics for power supplies since I don't have the C64's and do have a 12V 500 mA DC wallwart. So for option D using the one Vreg on the core you simply jumper the Vreg spots on the SID modules to get the 12V correct? as far as the 5V coming in from the core to the SIDs where is this connection at? I have all the data lines and J14 connected like in the optimized C64 powered version. Just curious as to the purpose of the Vs and Vc holes as well as J2. Also, So far I have power going to the 3 PCBs J1's and the core Vreg is getting super hot as is, but not shutting off. Have you been using a heat sink for yours or is it maintaining well at high temps? The SID Vregs don't heat up in the slightest bit of course, but will jumper them anyhow. As is, my LCD is lit(it's http://www.mouser.com/Search/ProductDetail.aspx?R=UMSH-3267MD-UBvirtualkey66830000virtualkey668-UMSH-3267MD-UB ), but blank with a few characters popping up now and then and the only sound I get is a charging up and dispersing sound when I plug the DC jack in and out. If I get this sorted out I will definitely write up the alternative power schematic to post with the Midibox V2 setup less someone has a link i managed to overlook. Now for some pale ale and solder fumes. mnnnnn....

the chromatic scale switcher for the ribbon seems to get in the way. MIDI-IF kit doesn't seem to work for these. found oints to put the pitch CV but it seems to be wired to work with the ribbons 5k pot and won't take straight CV signals. Waiting for someone smarter to figure it out.

Anyone else on here played with the monotrons? I've been trying to figure out the Monotron Duo's Pitch CV. The other two are a piece of cake since standard CV/Gate connector pads are on the back, but the Duo is odd. It has 6 waveform patches (3 for each oscillator) but no pitch CV.
