now We had a small amount of kits with a few missing components that arrived now.
-
this is limited to the first batches with the green jumpers and a fully populated PCB. I first intended to use the mainboard as some kind of universal mainboard, thus gave it ADCs. The first firmware versions even had a define for 4 outs or 2in/outs…
-
seems like a mixup of the enclosure print :-. I'll try to make 'em swapable with the next firmware
-
it is just 1 resistor that has changed. R21 has to be reduced from 100K to 10R. there should be a version number on the PCB. starting with version 0.4 the resistor change is not neccessary anymore.
-
the trigger outs generate a short 5V signal on the outputs which can be measured. have you stuffed all 10 of the metal bridges?
-
how is the LXR hooked up? the other outputs are working as intended?
-
reset in works more like a start/stop in. As long as the reset in is high the LXR will be stopped. when it goes low again it should start at step 1 of the current pattern. which enclosure do you use?
-
Trigger In PPQ is for the clock input to sync the LXR to external clock signals. The PPQ setting will only influence the speed of the clock the LXR will send out. Have you ever used the Trigger outs sucessfully before so we can rule out a hardware f…

some exhausting weeks have passed. #:-S We are set up with internet at the new location :-)) The shop is open again, but since the office is pretty much still a total construction site, things will start slowly over the next days. Penrose kits sho…

can you check R11. the 10 ohm resistor next to the 2nd button on the right side... all 4 non working LEDs are connected to this resistor. check the soldering and if you used the right value.
-
which buttons are affected? they are wired up in groups of 4. so if i know which buttons I can pürobably tell you where to look
-
if you burn the bootloader the main program will be deleted. the bootloader will only start if you hold down the encoder during power on. the normal firmware has to be installed via the bootloader from SD card after the bootloader has been flashed, …
-
No problem. The short beep you hear is due to the capacitors charging. In the other direction the long beep is due to the protection diodes. They short out the power rails to GND if connected backwards. With a real PSU connected the Polyfuses will t…
-
no that should do the trick. you don't have to programm the eeprom. zhe eeprom is used by the software to save the pattern during power cycles. so if the module is working you are good to go
-
in the prototype I have here the lightpipes used in the erica enclosures fit perfectly (even without glue ) So if there was no change I am not aware of the LEDs can be mounted flush on the PCB.
-
$-) yes! let's hope the final protos are good!
-
can you send me an email with your order number and I will send you the correct parts. sorry for the inconvenience!

Another thing to note regarding the "Higher pitch, more distortion" is that the quantizer will not operate at full audio rate, so additional to the bit crushing it will ad a sample rate reduction to audio signals. The trigger in jack controls the m…
-
All working like it should! The way you hooked it up the quantizer will act as a bit crusher ==> distortion it will make something like that out of your sine The more buttons are active, the more steps the resulting staircase waveform will hav…

... aaaand found it. I uploaded a new version to github that should fix it (0.36)
-
confirmed No idea what could have caused this. time to investigate...
-
glad I could help
-
ah yes some kind of versioning would be a good solution. the off setting just moved one place to the back. maybe I'll pull it to the front and make it a new version my changes were not really big. The filter click was fixed by resetting the filter…
-
Not as easy as putting both files on the SD card. The Firmware is stored in the flash memory of the mainboard. It only reads the file from the SD card during a firmware update. It would need a software modification so that both OS versions are sto…
-
Lights switch off? Does it happen when you move the power chord? regarding the filter. Which filter type? is it on all presets? If the sound engine is working in general the filter should work, too. It is all software after all. So this can not be …
-
is your AVR seatet completely in its socket? The update should take about 1 minute max. The thing is first the AVR is updated. It then tries to reset the mainboard processor and waits for its response.So when the Reset line to the mainboard has no …
-
the thing is that I just appended the new filter to the end of the list. So it sits in the spot where the "Off" setting was before A better solution would have been to have the off setting in slot zero to begin with, but changing that now would af…
-
Is it planned to implement the features of Brendan's firmware? I still have a few bugs on my todo list. So my plan would be to fix my known bugs to finally set the version number to 1.0. after that I'm open for new feature additions. I had a quic…
-
Where is the difference of the new filter model compared to the old one? First I thought the transient pop would be due to the rather complicated zero delay filter I used on the STM32. So I tried to implement a really simple naive 2 pole filter. As …
-
Firmware v0.35 --------------------------- - fixed transient pop filter bug (i.e. kicks sounding different depending on BPM and step position) - added new 2 pole lowpass filter "LP2" - fixed USB VID/PID - MIDI Bank change now select drumkits (progra…
