I've run into some bleed over with Audio on a TT build. Any ideas on where I should look to troubleshoot this? One channel (R) is ok, the other one (L) bleeds some of R's signal. For example when I play a test sine. Would this have something to do with "(not shown: right input is normalled to left i...

Anyone got a working Prizma+ ? I'm just finished building and trying to figure out its modes, etc. However, my LED colors do not match those in the user guide. Would like to find out if this is normal or due to some janky LEDs or ??? It took me a bit to figure it out, but, I believe you are in a di...

Is there a Build Thread in the DIY forum for Plancks?

I did a quick search, but didn't find a thread. Seems like it might be needed if there's a problem with the switch being inverted. I've also read a report on FB that the Mod Pot is reversed as well.

What I'm exploring are larger LCD screens (4") as an additional way to display elements of the Pd patches. I'm pretty sure the OLEDs and the LCD screens would work together and wouldn't necessarily be mutually exclusive. Pic of the LCD screen I'm experimenting with: https://www.muffwiggler.com/foru...

however two or three oled displaying different information would be awesome too. Further investigation on multiple OLEDs - we would need a breakout board to do this because all of the OLEDs default to the same i2c address. Adafruit has a thing that solves this problem: https://learn.adafruit.com/ad...

Emailed dev at 2 different addresses about ordering a Prizma+ PCB, but no response yet - it's been a coupe weeks. :(

Maybe just a holiday season thing?

Thank you very much, the template is very helpful. At the moment the "where" is the big question. Should I write the patch directly on the PI (with a remote Desktop), or is it better to develop the on a Mac/Win and transfer them afterwards? Either way will work. I set up SAMBA on the Pi so I could ...

Could you explicate the wiring of the stereo jack for MIDI In? I think there's only 2 ways to do it, but I'd rather do it right the first time.... The side (ground) pin goes toward the 3rd hole in the pcb. BUT - you don't need to connect the ground pin. Initially having trouble compiling the code. ...

Quick notes: The DUBLdeca uses 2 complete Dodeca units - this means two sets of everything under the hood (pcb + parts*) - with ONE Dubldeca panel. This also means you need two euro power connectors. Or you can make a single power cable with two power connectors (pic below). Not sure if the BOM is u...

Is there a V2 Schematic available? EDIT #1 - I'm dumb. someone above mentioned it's on the Github now. Trying to make sense of it is another matter. My problem: I've got one working fine and a second where the tuning (Coarse/Fine) knobs aren't doing anything. EDIT #2 - SOLVED! Bad solder joint on th...

yeah, pretty confused. kernel is 4.9.33+ #1010

EDIT: Went ahead and built up two brand new sd cards with the latest Raspbian (4.9.35+). All is working well.

Build #2 AOK. :sb:

Re: stuck

So my next (perhaps crazy) thought is - how hard would it be to convert this C++ program into a pd external that writes directly to the i2c oled display from pd (instead of piping the data via stdout/stdin) ? I'm currently wading through some pd externals tutorial videos - but I'm wondering if max ...

Give a good look at the 100n's 470n's (the ones over there around the electrolytic caps) and also the two 47K resistors
