I'm currently not at home to check my settings, but I used a MIDI controller just a few days ago to control some voice parameters like FM amount and Freq with CCs without problems. Of course the voice midi channel should match.

ah, someone noticed yeah I have to overhaul it sometime in the near future, but at least I brouht everything to a consistent colour scheme

7.5V - warm 9V - hot, still able to touch, but quite hot (also depending on how many LEDs are on) In general one can say as long as you still can touch the regulator it is ok. If it gets too hot it will shutdown itself. Electrolytic caps next to it…

it should not pull 680ma I doubt a wrong firmware update could do this. If there are normal IO pins directly connected to GND (which there are none on the mainboard) and the firmware would put them to +3.3V the chip could get hot. But on the mainb…

altitude is right. the stm should not get hot. can you make a high resolution picture of the mainboard?
-
I just received the tracking information for the next batch today. So probably in a few days.
-
you have to update the firmware in memory. hold down the encoder while turning the power on and the firmware file on the SD card will be installed/flashed to memory
-
atmega644PA should make no real difference since the P only means its a pico power device.
-
hmmm sounds like a short somewhere. I can think of no real reason how a firmware update should cause a voltage drop. with a turned off unit, what resistance do you measure between 5V and GND? Best tho measure this on the frontpanel and the mainbaor…

I think the problem is when you directly save the file from the 1st post in this thread. It is not a direct link to the firmware file but to the github page This should be the direct link to the file: https://github.com/rstephane/LXR/blob/LXR-marim…

this is a hard one! so it happens when the plug is half way in, probably when it shorts the outs to gnd inside the jack... :-? maybe there is a short between the plug detect switches and the AVR reset line? could you check the soldering on P2 on …

regarding a cold solder joint - just reheat the solder joint without applying more solder. The point is just to re-melt the existing solder. Sometimes it looks as if the connection is good, but the solder has not completely melted to the part and ha…

sorry for my late reply [-O< so the step is working and only the LED is wonky? you can turn the seq step on and off regardless of the LED state? if you take a look at the schematic on page 7 :-B http://www.sonic-potions.de/sites/default/files…
-
@kloroplaster yes. I talked with girts before they went off to the powder coating company and told him to keep an unpainted one for you.
-
which firmware version do you have installed? It is shown during bootup.
-
good point. In general this should be an easy addition to the code.
-
header error normally means it can open the file but the content is wrong. firmware images should start with 'SPFI' when you look at them with a hex editor.
-
if you have one of the very early boards you have an additional ADC on board (if there are no free spaces on the mainboard) on the other boards you can add an ADC if you can solder SMD. That's what all the green jumpers are for. In the beginning …

oh its been a while since I wrote that if you look at the sequencer code: //every 2nd and 4th 16th note in a beat is shifted full //=> step 8 and step 24 //every 2nd 16th note in half a beat //every beat has 32 …

schematic is online www.sonic-potions.com/public/PenroseQuantizerSchematic.pdf

That's no problem at all. In fact these 2 pads are already connected with a PCB trace. Both are +5V. That's why you can't remove the solder. the small line between the 2 pads is a trace. Only the 2nd pin is not connected to the capacitor but that…

following papernoise and loderbast here is my take on a short demo video
-
yes it is. I will upload it to github over the next days when had time to clean it up a little bit
-
give me a good interface idea... I've been thinking about this but found no acceptable solution so far. If I only want to implement the synth engine I still need hands on control. A eurorack module with just 4 pots + encoder is no fun imho. A singl…
-
Yes. should also be available in the shop soon
-
I know its a long long shot but it would be great to get a panel PCB designed for 1/4" jacks with appropriate spacing for larger buttons. (as found on the LXR) This PCB could be an additional item in the shop I think an additional PCB is less troub…

the quantizer is now available in the shop http://shop.sonic-potions.com/index.php?route=product/product&path=63&product_id=67 But I just found out I 'm missing some stupid 16 pin ribbon cable connectors for the power chords and have only 3…

when it crashes does the sequencer continue to run (playing sound) and just the AVR resets (bootscreen is shown again or weird characters) or does everything stop immediately? does it also happen with an unconnected cable without being plugged into…

does it happen on all 4 audio outs?
