gah i don’t have that much time to be reasonably helpful but maybe try messing with the firmware ? like commenting out that knob code to see if others function normally, etc. there was a feature in that firmware that sent messages repeatedly - i think i deleted it but i could’ve forgotten to in the repo or goofed on it somehow. value jitters smells like a hardware problem but, yea it’s pretty easy not to mess up this build, idk

no dice—no matter how i mess with the settings it’s always that knob going off which definitely makes it seem even more like a hardware problem… I guess I’ll try reflowing the potentiometers before i try removing the teensy :skull:

#28

definitely worth trying reflowing the smd (and the rest of the components while you’re at it), it can be the magic fix. that ended up being a fix to a module I had went though visibly and even with the multimeter to check continuity and everything looked right.

I think I had similar problems when I did my veroboard version. Using 100k pots Instead of 10k seemed to be the issue for me.

I ve had the same problems with my teensy controller.
Found some code on the web that might be usefull (or not) worth giving it a go
Here (shameless promotion):
look inside the ino file:

your code (adjusted for 7 knobs) appears to have fixed it! there’s still a bit of weirdness with pot 1 where it’s sending bank select data as well as 102, but it’s not a constant stream of data and in practice i can use 102 data still. Might reflow some of the solder today just to be sure but this has made it workable, which is a relief—thank you !!

just comparing the code have no idea what made the difference ! computers! how do they work!

Glad to be of help! Yes that might be contact problem, check ground is going into the problematic pot.
The code is not mine :slight_smile: But it works!
Go enjoy it!

Finally got my boards from OSH Park last week and built a bleached yesterday - super cool! Thank you for sharing, @andrew!

I modded the firmware to have two sets of 6 CC’s! It uses the first knob to select which set, and uses the teensy’s led as an indicator. LED off is cc’s 103-108, on is 109-114.

I def will! I need to clean it up, I’ve never used c++ before so I am sure it’s really sloppy code lol

I’m using 6 knobs to control the filters on Otis, if I could have 12 knobs who knows what I’d do!

After a week with bleached, I’m in love with it. Sure, I have other boxes that do the same (and more), but they take up half my table space. bleached is barely there, it’s like an expander for Norns, and that makes it trivial to map params wherever I am sitting - which means now I’m actually taking advantage of that.
(it’s also wooden and I’m a bit proud I put it together)

Thank you, @andrew and @tehn

@pfig @thopa, here is my code! Just flash it the same way you did the original firmware.

it seems like it would be trivial to add some extra LEDs and “zones” to first knob allowing for many more CCs, if one were so inclined :grin:

Has anyone had any troubles using bleached with Ableton? I don’t have Live myself, so I can’t really test, but I am getting a report of frequent disconnects that require an un-plug/re-plug of the device to return it to use.

#45

And this report comes from me. Anyone having trouble on Ableton and/or Mac with connection dropouts? I’m able to connect bleached (or Ableton reads bleached) and midi map controls, then mess with them for about a minute before the connection is lost. At that point, bleached still shows up as connected in Ableton preferences, but no messages are sent. If I unplug and plug back in, it sometimes picks back up where I left off.

Everything seems to work just fine on Norns (no dropouts after about 10 minutes of play). So I’m confused about what may be going on.

Thanks to @pfig I now have a Bleached PCB in my possession. Wanted to order the BOM but things are out of stock and I’m not competent enough in electronics to hunt down replacement parts. If someone is willing to help I’d be mighty glad!

Edit: Think I found everything but it’s from different suppliers. I n Sweden we pay custom fees on every package with is a real pain when ordering small chep things like this. About 10€ per package just to get it in the country. I’ll probably hold out and hope one supplier has everything in stock soon.

Yes! Thanks @Justmat had not seen your post before.
So depending where the first pot is cc numbers sent by the device are modified! This doubles up the fun.
So glad i got all my monome stuff packed and ready for some deserved holidays :slight_smile:

~~ hey bleachers ~~

just quickly added some part variants to the BOM while I was shopping. the length and number of positions doesn’t really matter for the headers, it’s pretty easy to trim them down to whatever

here’s my mouser cart. I’ve been getting sifam knobs and alpha A10K pots from thonk

when I build another pair I’ll try and check up on software issues and see if I can clean up the firmware a little. I’ve been mostly using it w/ norns no problem and didn’t notice anything fishy when I was testing in ableton

I was wondering, is there a way to assign bleach to one of 2 norns connected Midi to cv devices and transmit sth like scaled cv or anything interesting as modulator? Would be quite cool i guess
