just got my PCB/Panel yesterday, starting sourcing components and building this! ;-)

If I wanted to add a eurorack power connector what would I use? Can anyone point out a Schematic showing what a typical power scheme for Arduino and eurorack? The Arduino Nano I have says Voltages: input 7-12V on the back. I’m guessing I need some sort of regulator. you could use the +12 or the +5 ...

This looks like a cool project for a an "analog" ;-) polysynth :-)
I am also on the waiting list for the boards on Tindie, but they are always out of stock, and also found out the guy doesn't ship to Italy.
You have a PM if you still have some boards left ;-)

ahaha I just found this equation on the net: https://greggman.com/downloads/examples/html5bytebeat/html5bytebeat.html#t=0&e=0&s=8000&bb=5d00000100820000000000000000141d0398331485f67e0b28b0c176664eb1ec3bdae84654e054dc46ca9f83a3798889d917d3a224d0c4f5fbae609e8b4c91e47e82a89af25991299636276d2aaa41d468b2...

Quick demo of my Clock Out mod, so far it's working great. Clock out goes into my Keystep which in turn sends clock to a LXR Drum Machine and to a UNO Drum, with some live tweaking of Glitch Storm

I have added PERMANENT clock out, taking the 5V directly from one of the free pins (Pin6) This requires a little hardware hack (as simple as a jack connected to digital Pin6) and some software tweaks to get the 5V on pin6 I'll double check the code and publish the hack as soon as I debug it 100% ;-)...

I have added a CV input, by simply wiring a 3.5mm jack on the first potentiometer so I can send CV signals to it. It works!
Now In plan to add CVinputs for each parameter and possibly clock in/out ;-)

yes, I have used caps on my buttons, the main concern would be the BluePill board (I have used some female headers for it)
also, the screens should be raised a bit...(maybe sing headers again..)
I was looking for some wooden boxes today at the flea market but couldn't find any...

I changed SAMPLE_RATE on one of my GlitchStorm :
this way it's more in tune with a "standard" C of 261.6 Hz (it should be at 261Hz for a 440Hz tuning) so I can play other synths on top of it

is someone able to design a case for the OR? Acrylic or whatever, it would be handy ;-)

Opera Rotas by Spherical Sound Society :-)

I just made a quick demo-jam using the Opera Rotas in sync with my LXR (using Clock Out on the OR)
This thing is wicked!!!

I just received a pre-programmed Blue PIll and (of course) it works! Finally!!! :sb: (please, we need a 100% working procedure to update the firmware in the future using the St-Link and and .hex file...I don't want to "break" the current working board, so I have a couple of Blue PIlls replacements.....

Yes, correct. But I won't be able to connect it to my Mac and use it as MIDI-USB controller or reconfigure it, update firmware and so on.
Only Eurorack use ;-)

I recently traded a LXR (with Metal case and separate outs) in echange for an Ambika I had built. I absolutely love it. I am using BC Firmware, loving the "Morph" function, as well as the "Sample Rate" reduction. I am syncing it with my modular and other stuff and works and sounds very well. I Still...

Well, I have fixed it. :mrgreen: :mrgreen: :mrgreen: I stripped a standars USB Cable There was just enough space to "see" the D+ and D- pads on the bottom of the board and soldered the white and green cables. then it was just a matter of soldering the red wire to Vin and black to GND, which are the ...

Tonight while pluggin it in, the USB connector on the Teensy came off... The Teensy is directly soldered to the board, since there was not enough space for sockets.. How can I try to repair it? I know there are USB pads on the bottm of the Teensy, what about on top? maybe a bigger USB connector and ...

It seems you failed programming it. You have a new microcontroller on the way. It´s going to work, word! I really hope so. But then , you need to make an idiot-proof guide on how to program that STM32...for future updates to the Firmware... (programming looked OK, no errors, but I have some doubts ...

nope, screen replaced, still no sign of life....

ah OK I didn't know it would not boot without the display connected.
I think I have another one I can teporarily take from another module I have...or maybe Amazon has one on Prime ready for tomorrow...
thanks

I finished building mine, after lots of struggle I (apparently) managed to program the Blue PIll Then I switched the OP on and noticed that the screen was getting really really hot, at one point it became red and something burned, i presume... I measured -3.3 Volts on the screen VCC/GND and then rea...

Regarding the tuning, it uses powers of 2 tunings (16384hz) , so I "guess" is normally tuned to 432hz. You can probably change it hardcoding some other figure that will be in tune with 440hz (1698x?)but honestly I dont know exactly what is. If somebody has the maths I can include it in the next fir...

is it just me or it produces (in the more "melodic" modes) a C note which is offset by +25-30 cents ???
I have tested with some VST synth and I need to set it to - 25 to get it in tune with external stuff ;-)
how can I change the root note in code or compensate the difference?

I just received the PCB today, took me about 20 minutes to build. Excellent glitchy sounds, I like it!!!

I made a short demo while tweaking some knobs on one of the modes
Drums, Delay and Reverb added in Logic

yes, please add clock in :-) This would be a killer integrated into a Modular setup...
