  • the design files for the acryl case are in the wiki. So you could get them made from a service like ponokop or formulor. We just sold way too little to justify keeping them in stock. The metal case comes with lightpipes, so normally the LEDs should…
  • doesnt matter. It regulates the LED brightness, so 1ohm difference is not visible.
  • there was a flyer in the kit with the URL to the build guide, quickstart manual and firmware image: http://www.sonic-potions.com/lxr-quickstart http://sonic-potions.com/public/SdCardImage.zip the latest firmware can also be found here in the foru…
  • yes remove. I tried it here and it solves the problem.
  • Good find! try removing R28 (3k3) bottom PCB in the top left corner next to the AVR. I'll update the build manual soon. Seems I planned to use 12V for the gate out voltage source but connected 5V. The voltage divider is dimensioned for 12.
  • could you post a high res photo of the boards? sure you put the 10 ohm resistors in the right place? any higher value and the LEDs won't light up. so a single green led is lit but nothing else? Is this the button LED or the gate out LED? do the …
  • with nothing connected the penrose should stay at the low C (uppermost button) it seems it has a voltage offset on the input that falls between 2 notes. looking at the schematic: www.sonic-potions.com/public/PenroseQuantizerSchematic.pdf I'd chec…
  • normally the midi input of the soundcard should be isolated by an opto isolator. so in theory there should be no way for GND loops. do you have a midi thru box or another midi thru device to test this? If it does not happen with other MIDI devices I…
  • looking better and better
  • should work now
  • the other question is what you will use the synth for. Do you plan to use VSTs together with it? multitrack recording? or are you looking for something to make multiple voices at once?
  • rocket seems a bit boring to me. A shruthi is great for bass and leads (monophonic) and beats the rocket in every aspect. And it's easy to build. xoxbox vs RE - I have both. Xox is way cheaper, and I'd say gets to the original sound about 80-90%. R…
  • yeah, murphys law strikes again #-o I thought it would be impossible, since we test each boards audio IO, SD card and general functionality before shipping them out. And even have the boxes with programmed and unprogrammed boards in different shelv…
  • currently I'm waiting for the samples for the knobs and button caps Software wise the sysex im/export and some tweaks for the additional midi/dinsync IOs is still missing. So My uneducated guess would be 2 months.
  • I'll contact you via email shortly. Sorry for my late reply!
  • 1) case files can be found in the wiki: http://wiki.sonic-potions.com/index.php/Enclosure_SVG 2) no I'm afraid not. The PCB is a few mm higher than a normal eurorack frontpanel.
  • which firmware version are you talking about? I could compile it for you, no problem. I'm just still in the landing phase after superbooth and have to catch up with mails and forum posts.
  • full diy kit. the slide is added to the CV + a gate is output on slide notes on the slide out. CV slide can be deactivated to use the slide out as extra trigger track or for external slide modules with variable slide time for example
  • Is this the later version with the little O-rings?
  • I'd love to give them a go, but currently the RE-303 CPU is keeping me super busy. Soundcloud demo sounds great though!
  • All I have is listed in the wiki http://wiki.sonic-potions.com/index.php/Enclosure_SVG I'm, afraid I never got working SVG files for the official enclosure from fcd72 :(
  • The frequency range is selectable by a jumper. You either get suuuper slow cycle times down to 10 minutes, but no real usable audio range, or not so slow cycle times but noise up to audio range. No v/oct tracking. The module is not usable as a class…
  • do you have a SD card in the slot and also at least one preset on it? The error message means the LXR can't read the initial preset file from the SD card.
  • Hmmm I think I have bad news for you. My guess is that the OLED is broken :( As it is not a graphical display it normally can only show a predefined set of characters and I know of no character thats just a few pixels wide line. To be sure you cou…
  • you can just use the continuity (*BEEP* when the probes touch) tester on the multimeter and measure if the pins of the avr are connected to the corresponding pins on the LCD. and if the 5V and GND pins are connected to the marked pins on the avr isp…
  • these are the data lines from the AVR to the OLED additionally you should have GND ond pin 1, 5 and 16 and +5V on pin 2 3,7,8,9,10 are not connected. by one line do you mean the whole upper row of the display is a solid line or is there just a sm…
  • it's the cliff k87MAR series k87mar BLK 6mm USAD white or CL170822FR Afaik these should be the same, but I get mine directly from cliff. So be weary, as they come in all types of shafts and sizes and I have neither ordered from conrad nor rapid yet…
  • I will fix the next bug and make a LXR patch day when the current projects are finally done. Sorry for the long wait. roadmap looks a bit like this: - mal-2 kits -> probably next week - RE-303 CPU -> first boards next week - Malaclypse eurora…
  • ah ok, that's an option. no jumpers are not necessary anymore. The first boards had an ADC option with the idea to re-use the board for other projects, but in the end it seems more economic to me to make dedicated boards.
  • this is the one i used before http://www.mouser.de/ProductDetail/STMicroelectronics/STM32F407G-DISC1/?qs=/ha2pyFadui1YcVs9LwlR5Wqc4ZUxCtym584avAZKUykGi5nsHymTw== This board only has a stereo out. On the LXR board I use 2 external DACs to provide th…
