Swapping firmware is easy, quick, can be done over and over and sorry not require recalibration.

#245

Yeah, that’s been floating around since it was apparent that we’d hit the flash limits sooner than later. The way it’s set up right now (which is still based on what I consider throw-away code) it kinda-sorta works to comment apps out in one place, but it really needs proper support and a real build environment (i.e. not the Arduino IDE). I started to refactor things almost to where it was becoming more feasible, but it’s tedious and not particularly rewarding so… well, it’s not really a priority. It might work better in Hemispheres but I’ve never looked that closely.

The often requested corollary is to have some kind of web interface to build custom combos, but actually doing that doesn’t sound very exciting either :wink:

Anyone have a favorite video tutorial for newbies?

#247

I would say there aren’t any video tutorials for O&C, just overviews, what do you want to know? The manual is pretty good, start there.

#248

Thank you. Nothing specific, I just learn fastest with video! With the docs/manual I’ve had a hard time imagining/hearing in my mind what each app does.

#249

Actually, while they’re not comprehensive of ever tool, this channel has some good run throughs that helped open up my thinking about the module:

Oh awesome, thank you!!

He also has been doing Hemisphere videos recently too - loads to learn

I have the o_c in MU format. Have had it for weeks and never left quantermain mode lol. I really only use it for the Turing machine and quantizing to scale.

I do like the idea of hemisphere allowing for 2 separate functions. Can one of them still be a quantizer/turing machine? I would love to have one half be a logic function or comparator or such.

#254

Yes, ShiftReg can handle both. The output is a little wide-ranging if you quantize but for 1/2 a module it’s pretty great.

It goes without saying that the regular o_c apps offer a lot more depth individually, so you lose things like scale masking, etc.

Dumb question. Why don’t my app names match up with what’s in the docs?

There is a “simple names” edit of the firmware which is used on 4ROBOTS units. It also has the VOR function by long-pressing the up button

FWIW if you build your own firmware, there’s a #define in OC_options.h to change the naming.
I made a silly version that has a secret handshake to switch at runtime a while back, but flash was scarce, so…

still been having some mystery interference from my O_c, moved it to my other rack and things seem better so far so maybe my power supply on the other one was just overstretched

#259

Does the frequency change when switching from screensaver to selection menu?
I had the same issue with mine and “solved” the problem by puttig the affected modules on one bus board and O_c on the other. At some point i had the impression the problem was also related to the position of the modules relative to each other (same row)?

#260

It did seem to change according to what’s on the screen. Based info I found last time I looked into it I added a big filtering cap somewhere on the OLED but that didn’t seem to help. My power supplies are small DIY ones with only one bus each (one is a flying lead and the other just a bunch of pin header soldered to a stripboard) so I don’t have much options re: rearranging them. But yeah moving it from one case to another seems to have helped.

edit: also even tho the main interference noise is gone now it’s in the other case, I still get some small ground hum problem somehow related to the O_c when I patch the two cables together. need to experiment more

#261

I was hoping for a simple mod like adding a filtering cap somewhere. i’m considering to switch to a new more shallow case. due to space limitations i won’t be able to install 2 seperate bus boards. Moving it around is not really a solution. :thinking:
Does anyone have another idea to address this problem?

I’m likely going to build an o_C in 4U for a DIY Serge/CGS panel; I see that it’s pretty easy to mod the currently-available PCB for banana jacks, but I’m wondering if anyone has seen either and Eagle or KiCad file of the board? I can move stuff around myself if I can find one…
Edit: Found a PCB on Modular Addict!

#263

Just a “Today I Learned” - Not sure if this is addressed in this long thread, but “Ornament and Crime” originates as a title in this essay: https://en.wikipedia.org/wiki/Ornament_and_Crime

Great reference and name for a module, if intended.

I don’t have anything concrete since a) to my knowledge it’s not been a commonly reported issue (*) and b) it’s not a single diagnosable issue, but rather interactions between module and power/bus. So I doubt any simple mod will help, other than improving the latter. And if there were such a mod, I’d vaguely assume someone selling them might have made it already (yeah, yeah, assumptions…)

It doesn’t help that some screens emit physical noise as well, some louder than others…

(*) Which admittedly isn’t saying much about how pervasive it is…
