After checking everything possible, I think I solved my issue with PITCH opening all voices 5- to 8 I din't put plastic washers under the small "pad" screws because "hey, the panel is made of PCB material, it's not conductive". Well, I don't know what happened, maybe the DIN Screws scratched the sil...

1st, check your board to board connections at TRNS2. 2nd, check the soldering on the #2 NXP 4093, and make sure it's not backwards or has any bridged connections. 3rd, near that NXP chip there is a 547 transistor, check the connections and the orientation of that transistor. 4th, as the voices are ...

I have finished building mine. I have an issue on the PITCH knob for voices 5-6-7-8 (first four voices are OK) If I turn the PITCH knob up at about '9 o clock it starts "holding" voices 5-6-7-8, and they all play together (the HOLD knob is at zero). Opening the PITCH knob more changes the pitch of t...

OK, thanks a lot. Yes, I have the two small rectangular PCBs for "Shields", I just was not sure why they called them UP and DWN when they are actually one on th eleft and one on the right. Thanks for clarifying ;-)

I am a bit puzzled by the build guide, regarding the "Shields" it says: Install the shields on the bottom side of the main PCB after soldering of all other parts. Places for installation - see PCBs/Place for shields.jpg Use UP holes for upper PCB part and DWN holes for lower one. what do they mean b...

I need to try reflashing the firmware on a MiniClouds for a friend's friend. It was supposed to be working then somebody installed or tried to install Parasite. Then tried to remove it. Currenlty, the module lights up and all leds are on, so at least we know it's not dead. However, when trying to up...

Cool. Waiting for the orders to open.
will probably be one of my spring projects !
(still need to finish building my winter projects ;-) )

I believe you are missing the "ecuaciones.ino" file which is needed by the "main" code in the .ino file

Did you find those DIN653 M3 somewhere? I'm also Europe based (berlin). Seems quite expensive everywhere..

yes, on Aliexpress (not really Europe, actually )

https://www.aliexpress.com/item/32975169127.html

They are listed as DIN653, just make sure you get the right ones M3 x 12 mm

Thansk for sharing I want to to LCD replacement on my 5 Euros (yard sale, yes!) Casio CZ-1000 but I need to solve other problems first (very low volume for sounds but very loud noise out of the machine

Musikding.de also has quite some pots.. Germany based so maye faster than Tayda. But why do you need a stereo pot?

thanks, I bought them on Musikding.
BOM has some stereo pots. 4x C100K and 4x A100K

thanks,
i found most of them on Mouser, I am only missing the C100K single and stereo, no sign of them on Mouser...
I bought the "Knurles shaft" version with solder with circle terminals...

I started building mine, already soldered some passives, but I am getting mad sourcing all potentiometers. (Someon uses the ones with solder lugs, someone with "circles" terminals)

Does anyone have a good source link (mouser or whatever) for the correct pots? Thanks

THANK YOU!! that was it! ahhhhhh

(it happens all the times you connect this kind of LCDs )

the 2x3 pin header is needed if you want/need to reflash the Atmega CPU. You can omit that since your unit is pre-programmed.

Look at the pic for the trimmer to adjust LCD contrast ;-)
And/or have a look at the bottom of this page, TROUBLESHOOTING section: https://mutable-instruments.net/archive ... d/digital/

correct lcd contrast, there 's a trimmer IIRC

I have tested the new firmware on the "extra" Bluepill I had, so far it seems OK.
Installation is quite easy (once you understand what needs to be done ), when the FW is released as .hex file I can write a simple guide on how to do it if you need it

sent ;-)

I have an "extra" Blue Pill and I would like to help testing the new features, if you need it ;-)
I can't wait to see the new features!!

Are we there yet? Are we there yet? Are we there yet? ;-)

(count me i, pre-soldered or not, depending on the final price)

Let me start the 2021 thread with my just finisehd Erica Synth DIY system, it's been a long work in the next month or so, finished during the festive holidays ;-) (some details still missing, but 99% complete and working good ;-) )

In case anyone needs it, I wrote a mini-guide on how to program the ATmega for the MIDI-CV Module on my webiste.
I have used a standard Arduino Uno and swapped its ATmega with mine.

I just finished building mine...everything seems to work, excet I have a very low volume if I set the wave to Sawtooth. Square and Triangle waves both have a good volume. Any idea for this low volume on Sawtooth? I think it's maybe some misplaced resistor...but where??? ;-)

now it's my turn to be sorry, :-) it's not in the topic title but it's in the first line of the post :-)
