agreed, I don't want to make your ears bleed :)

That's actually exactly what I need. I'm gonna screen print the text and everything myself, so I just need the holes.

I'm curious if anyone has converted the Schaeffer Front Panel template found here: http://www.ucapps.de/midibox_sid/mbsidv2_front.fpd to DXF format for use in autocad. For my front panel, I used that as a starting point and then found out that my friend's brother works in a metal shop so it will be way cheaper for me to have him create the front panel rather than ordering it from Schaeffer. The cost savings would be negated if I have to order the DFX export filter from Schaeffer, so I'm hoping that somebody else has already converted the template and could provide it to me so I can use it as a starting point.

Man that's gonna be one mean lookin' synth.

Not Midibox related, but here are some tracks from a demo I'm working on: Koma Visions The Decline God is dead, we killed him.

I second the notion of calling it "Ãœber-Poly Mode"

I never did figure this out, but I ordered a new sid module, built it last night all all is working great now.

try saving the screenshot as a .png they are much smaller than .jpg

My LCD did something like that when I had it configured in 8 bit mode rather then 4. However, I'm not building the MB-6582...

Looks great!

nevermind, I cut and pasted a section of setup_tk2.asm and it seems to work just fine now. this is what I used: ;; number of LCD lines (supported: 2 for 2x* LCDs and 4 for 4x* LCDs) #define DEFAULT_LCD_LINES 4 ;; LCD line -> cursor offsets #define DEFAULT_LCD_LINE_Y0 0x40 #define DEFAULT_LCD_LINE_Y1 0x14 #define DEFAULT_LCD_LINE_Y2 0x00 #define DEFAULT_LCD_LINE_Y3 0x54

is this all I have to change in the setup_*.asm file to get a 4 x 20 LCD working with all 4 lines? because it doesn't seem to be working for me... ;; number of LCD lines (supported: 2 for 2x* LCDs and 4 for 4x* LCDs) #define DEFAULT_LCD_LINES 4 ;; LCD line -> cursor offsets #define DEFAULT_LCD_LINE_Y0 0x00 #define DEFAULT_LCD_LINE_Y1 0x40 #define DEFAULT_LCD_LINE_Y2 0x14 #define DEFAULT_LCD_LINE_Y3 0x54 does anybody have an already configured .hex file I could use? that is the only change I have made.

Ok, I loaded the test tone application and heard the tone from one sid module using a wire from pin 8 to pin 27 on one sid module but not the other. So It's definately the amp circuit that's at fault.

I pretty much came to the same conclusion yesterday.

I bought them from Smash TV

now the left has low volume

Unfortunately I don't have a digital camera, but I drew up a picture in paint to show you how I have the sid modules connected. I also have the +14v connection on the PSU connected to J1 on each sid modulesid_connections.PNG sid_connections.PNG

1. same issue 2. swap sid chips, still low volume on the right. In fact I have 3 sid chips, all 3 work fine in the left sid module but not in the right. 3a. everything is where it should be, polarities of the componenets are correct, soldering looks good, wiring to the core looks great, I checked the voltages accoring to the instructions on the bottom of this page http://www.ucapps.de/mbhp_sid.html and everything looks good. I found another thread suggesting that the low volume could be do to a bad voltage regulator, so I swapped that out for another, but to no avail. I still have the same volume issue.

I do have a display, it reads: E002|A001*LD Chn. 1 1***|Lead Patch the firmware is properly uploaded, I used setup_6581.hex J14 is definately connected I am thinking it is a problem with the right Sid module however, but is there a walkthrough for testing the Sid module somewhere? I just noticed that if I crank the volume on the for the right sid module via my mixer, I am getting some sound it's just extremely faint. (as such, I changed the topic title) It seems to me that it's definately a problem with the right sid module, but I'm not sure what else to do to test it.

I've just completed building a stereo midibox sid with one core, but I've got a problem that I just can't seem to pin down. I'm not getting any audio from the right sid module, I get audio from the left just fine. I've double checked all my connections, nothing seems to be wrong there. I don't see any shorts, and I double checked the voltages, everything seems ok there too. I've even swapped the Sids around to check if the sid in the right module was bad, but I still only get audio from the left sid. I followed the guide here for the connections between the core and sid modules: http://www.ucapps.de/mbhp/mbhp_8xsid_c64_psu_optimized.pdf Is there something I might be missing? Thanks in advance for the help.

The optimized PSU is very easy to slap together (I did it in an afternoon with no problems what-so-ever, and my soldering skills leave alot to be desired) plus from what I've read you'll get the best signal-to-noise ratio using that option. For the minimal control surface (someone correct me if I'm wrong) you only need a DINX2 but you could use a DINX4 with only 2 of the 4 shift registers stuffed.

I've read that theres an audio input on the sid chip, but haven't heard a sample so I'm not sure if that's what your speaking of. I'm new to this whole midibox thing so maybe one of the gurus could explain more.

<=== patiently waits for an update I'm about to begin work on my own Midibox Sid soon so I'm enjoying this thread, seeing what it takes to get one off the ground. I can't wait to see the finished product.

The dimensions of the (what do you call that the plunger?) don't quite look right. It's not tall enough. I found all kinds of switches on mouser with shorter plungers, but not any taller ones. Mouser's cheaper though with faster shipping, so I prefer them to digikey.

nevermind, I finally found them at digikey, part number P12226STB-ND
