Re: Super Sixteen build support thread

Hi Matthew, I checked everything as far as I can, and the connections seem fine. The 4822 outputs CV on pin 6 which goes all the way to the CV output on the front panel. There’s no pitch CV output on pin 8. Could it be a bad chip? Any suggestion? Thanks Izhar He Izhar, Sorry for the delay, just cau...

Re: Super Sixteen build - SOLVED! + new problem

Hi Matthew, I did all the tests you suggested, changed the mosfets and checked all voltages, but couldn't find the problem. I found the schematic on Github and started checking all connections to and from the memory chip. I discovered that there was no connection between pin 17 of the ATMEGA (MOSI ...

Re: MEM crash

Hi Matthew, Thank you for the email reply. I checked the soldering joints and even replaced the memory chip with a new one. Unfortunately the Super16 still crashes when turning the data knob. I'm attaching photos and a short video. Thanks! Izhar Super 16 Crash Video Hi Izhar, Overall the soldering ...

Re: Super Sixteen build support thread

Hey Extralife! I'm unfortunately still having the same problem. I have a 1/16 clock going to the Clock input and a 1/1 clock going to the Reset input but instead of it being synced, there is a double on the first beat. Which is throwing the timing out. I have sent 2 clocks as gates directly to enve...

Re: Super Sixteen build support thread

Update -- Turns out my atmega from the kickstarter delivery was not flashed :( ... It boots up now nicely and leds working, encoder is being read to the screen so it looks like that was ultimately the culprit. Will have to actually test and calibrate but for another time. edit: had a run thru with ...

Re: Super Sixteen build support thread

Hi, I have built a through hole version based on the PCB/panel kit from your kickstarter project. All is well, except on the 7 digit display the 1 is much brighter than all the other numbers. Is that normal? Thanks, Frank. Hi Frank, Yes, I notice this on my boards as well. It's odd, but I guess it'...

Re: Super Sixteen build support thread

I've got a weird issue with my build. When I power it up, the 16 small leds light up dimly, but I can see what I'm selecting. The two bigger leds don't seem to light up at all. I'm pretty sure I got the orientation correct on the big ones. I can't see any obvious shorts. Any advice as to where to c...

Re: Super Sixteen build support thread

That did it! Seems to be working and I'm off to test the outputs now. Thanks again. Sometimes all you need is another set of eyes. Excellent, glad to hear it! One other thing I'd suggest is to lean that 330uF capacitor *away* from the voltage regulator rather than toward it, as the heat the regulat...

Re: Super Sixteen build support thread

Just finished a build. Did the tests, all good. Plug it in..... and nothing. No Display lights, no button, lights,... Nothing. I went through the entire 2 boards and reflowed all joints, and verified polarity. Parts were bought using the Mouser cart that was provided. Oh no! Well there's a long lis...

Re: Super Sixteen build support thread

Hi, So after getting my second board, my super sixteen is up and running with no issues... it's really fun to play with. I do have a question though. Apologies if this is not the right place to ask, but... I am trying to sync it with my MPC X. I have the tempo synced OK, by sending a gate every 16t...

Re: Developing the Super Sixteen Step Sequencer (eurorack)

Hello again, Just as a follow up to what was previously posted. I have changed the hardware to reflect the newer schematics. I had a bit of a headache with the led and switches matrix, wired as per schematic would not work and had to refer to the gerbers to see how they were wired.. Looking at thos...

Re: Super Sixteen build support thread

Just finished building mine. The build guide is awesome, thanks a lot for that! Upon turning the module on, the lights blink corrrectly, everything seems to work fine, except that I don't get CV/Pitch (gate works fine). I've checked the MCP4822 and there's something fishy, as pin 8 seems to be shor...

Re: Super Sixteen build support thread

No ! but pins 11 and 13 connect with closest pins.You found the problem, i probably damaged the pcb. I can solder a wire between the ic and the header pin unless you have a better idea. super16-cpuboard-verso.jpg I have the exact same problem with the pin 2 gate output, i have no continuity with r1...

Re: Super Sixteen build support thread

OK, glad to see you're making progress! Your PCBs look ok as far as orientation and placement, but it would be helpful to see the solder side in a bit better focus if you can. You can also use the forum image attachment to get the photos inline and not use an external host (click on "full editor and...

Re: Super Sixteen build support thread

Perhaps the screen is broken? It should be easy enough to test this theory. Unplug the module and use your multimeter in diode test mode. Connect the positive probe to the display's top row, 3rd pin from right. Connect the negative probe to the top leg of any of the nearby 7 resistors to the right ...

Re: Super Sixteen build support thread

Hi The pdf and the video are very clear thanks for that. I just finish the build, but i have two problems : -The second number in the screen doesn't work. -no gate on output. I think soldering points are all ok, all ics are well powered, all the ground i can check are ok. Do you have an idea to fix...

Awesome job! I've just become aware of your work. Is there anywhere I can buy a panel and PCB now that I've missed the kickstarter? Thank you!

Re: Developing the Super Sixteen Step Sequencer (eurorack)

Great, inspiring, educational and more than anything else superb sequencer packed with features!

Re: Super Sixteen build support thread

I have seen the "NEN" message yesterdy, the "daughterboard" was probably having bad contact with the main board. Then after tightening the daughterboard it disappeared Is there some kind of manual? Mine is always in a "play" state, if I press the various buttons to create steps, nothing seems to ha...

Re: Super Sixteen build support thread

I'm getting "nen" on the display when I boot up which I'm guessing is a memory issue. A turn on the encoder crashes the board. I can't see any shorts or obvious unsoldered joints on either board. Has anyone else had this issue, and where should I be focusing my attention to get it working? Fantasti...

Re: Super Sixteen build support thread

A few changes from standard spec : The 17 black push buttons are 5.9mm x 10mm items from Ebay, because Mouser were out of stock, and Digikey etc are v. expensive for small orders. Panel holes enlarged to 6mm, buttons modified by drilling out to 3.3mm dia, and are a nice enough fit that panel can be...
