This is probably a really dumb comment (not being familiar with norns code) but arent there abstractions at the driver level in raspbian that would cater to both? eg snd_soc_wm8731
Again, sorry if this is a really stupid obvious comment…

#521

Nah… it’s just a norns code thing. (I believe) The hp level on Norns hardware is sending an i2cset command and they use a custom driver (snd_monome I think)

So you can do the following from maiden to change the hp volume on fates (use at your own risk :grin:)

os.execute("i2cset -f -y 1 0x1a 0x05 0x0")

Will set it to zero - last parameter there is a hex value for volume. 0x70 is a good medium value.

Hi fellow nerds,

I’ll most likely build Fates soon enough, i have not been that excited about a project for a long time.

Looking at the Orac software makes me wonder though. Has anyone thought about modding the PCB in a way that 3 stereo output could be a thing? Since Orac can run 3 parallel chains, it could be somehow possible to output them separately? Would that even be possible?

Thanks! :slight_smile:

Question regarding soldering the usb-c jack.

When I insert the part the internal 14 pins don’t protrude through the pcb, but appear to sit flush with the top of it. Is this normal? In the build pictures they look like they’re protruding.

#524

I haven’t used Orac yet but I think that as-is it is “limited” to stereo output, you could certainly alter this though since it’s all based on pure data, but that’d need some work on the patches.
Regarding hardware you’d need more DAC outputs (fates, like original norns has 2 ins an 2 outs) so not possible by modding the PCB, but you could use an external class compliant sound card.

#525

Yes, of course some pure data sorcery would have to be made but wouldnt it be great? hehehe

#526

orac is not really limited to stereo output.
you just define your own router with the chains you want, and then send them to output using the standard dac~ object.

I do this with an organelle/fates using an ES-8 to send audio and CV out to my eurorack.

They are almost flush… as long as you are careful about bridges and the flux floweth, you should be fine :wink:

That’s great news, Orac seems so flexible. I had forgotten about the CV Tools, we recently bought an ES-8 at work (inside a MN shared system) can’t wait to explore this!
Building my fates tomorrow :slight_smile:

Update to what I wrote below: I got it to work. I guess there’s issues with Catalina and Etcher. Launching Etcher with the sudo command from Terminal did the trick:

sudo /Applications/balenaEtcher.app/Contents/MacOS/balenaEtcher

Here’s what I initially wrote: I’m sure I’m doing something incorrectly, but I don’t know what. I’m trying to flash the img file to the SD card that came with my Pi. I am doing this on a Mac. I installed balenaEtcher, and it runs properly (had to turn off the security on the Mac to get it to install and run), and then I popped the SD card into the Mac, where it was recognized. I selected the img file in Etcher, and then I selected the SD card. I hit Flash, and I was asked to re-enter my account password. I did this. I immediately got an error message that reads “Something went wrong. If it is a compressed image, please check that the archive is not corrupted.” I did this with the 2.2.0 img and the 2.2.1 img in the Fates GitHub, and got the same error with both. If anyone has a suggestion, that’d be super. Thanks.

Update to the update: It worked. My Fates/Norns is alive and Awake.

They might only protrude a tiny bit (I can usually feel them with my iron better than I can see them)

Just be sure you see pins in each of the holes (before you solder). I had one (out of many so far) where the pins bent - was quite vexing until I removed the thing with hot air and saw the bent pins.

#532

Follow-up question: I installed 2.2.0. When I tried to use the Norns update command, I got a “disk full” error. Any advice on what to do? Thanks.

#533

Did you expand the file system (and RTFM :stuck_out_tongue_winking_eye:)? (sudo raspi-config)

Ha! No, I will read up. I clearly forgot something from when I previously had a Norns.

#542

any luck? After reading your post I went back to my Fates and…no sound. The GUI and encoders and scripts all seem to be loading fine though.

#543

That’s what i was telling myself.

If the PCB files of Fates eventually gets released or when the Diy Norn Shield gets mature i just might try to design a similar PCB but with let’s say, 3 stereo output pairs, 8 encoders and proprer Midi in/out. It would make a very killer fully featured multitimbral synthesizer in a realtively small footprint.

I’d open source the whole thing because while i’v had my share of successfull SMD eurorack builds i am very new to electronic design and i have absolutly no clue about how to code. I know my way around Linux and Pure Data but that’s about it.

However, i’m confident that since alot of work have been done already in that regard with projects such as Orac, both Diy Norns, The Terminal Tedium and Seismic Industries Compute Module I could succeed. Especially if some like minded people with better abilities than mine jump on board (no pun intended) lol

#544

Well I finished mine, have to trim more the screen pins to be able to screw the bottom left 8mm one but otherwise it looks great.
Awake was working perfectly after startup, but then I updated to last version I now have no sound output either… :frowning:
I’m gonna try to investigate a bit this afternoon, or I’ll just go back to the previous version.

Edit : It sounds again after reboot, I’m gonna adjust jack buffer size.
Last edit : I changed Jack bufsize to 256 and it seems pretty stable for now, I installed Orac too without any trouble, I’m so excited about this, now to find some time to explore all these wonderful scripts before I create my own !
Thanks a lot @okyeron, @TheTechnobear and everyone involved :slight_smile:
