CV-Ins are reversed on startup #1

Closed pssssssst closed 2 weeks ago

pssssssst commented 2 months ago

Hi, i built the DIY version of oneiroi and everything works fine except the behavior of the cv-ins for the parameters. When i turn on the module everything is reversed. If i use the "shift + mod amount" button combination and then press "record + random" everything starts to work as expected. But i can't save that state. Holding "mod amount" for 2 seconds seems to save (blinks twice), but after a power cycle the cv-ins are reversed again.

Other than that i love the module. Thanks you for putting this together. I have been having non stop fun with this :) Best, Marc

I read this about the issue you describe; do the 'Shift+Mod Amt' on all the parameter and set them to 100% (fully clock wise), and now the CV seems to work correctly.

In the manual where it says this (section 14): Then, adjust the knob you want to be affected by the CV from 0% to 100% (the default is 100% for all primary parameters).

I assume there is a bug in the firmware were the default is not set 100%. (in my case it seemed to be -100% i.e. inverted). Now that I've set it to 100% I can't recreate the inverted behaviour

pssssssst commented 2 months ago

Yeah, thanks. i figured out how to change it to normal behavior. But as soon as i turn off the module and turn it back on again the inversion is back. It doesn't bother me too much, but it would be nice if the saving would include these changes.

I'm trying to reproduce this issue on several "fresh" units and cannot reproduce it. It looks like it is something only happening on some units probably due to a human mistake on the testing/calibration procedure.

@pssssssst you can save CV mapping by holding MOD-AMT Button until it blinks so you do not have to do it every time you switch your module ON. What serial number does your unit have on the back?

pssssssst commented 2 months ago

Hi,

thanks for the reply. My unit is a DIY so it doesn't have a serial number. I will try the calibration again.

My problem is, that holding MOD-AMT doesn't save the cv-settings. It saves everything else but not the cv-settings. After a power cycle everything is reversed again.

Also i can't seem to be able to connect my owl board via web midi. Does it need to be powered over the power bus or is a usb connection enough?

@blindorange The CV defaults are here, I believe:

https://github.com/Befaco/Oneiroi/blob/main/Ui.h#L183-L192

They appear to be set at 100%, not -100%.

Maybe the problem is in the calibration procedure?

i have the same issue , i calibrated 2 times .. we really need a new firmware ...

Yes you're right. can you connect your owl board to the web interface they provide?

rootapprox commented 1 month ago

yes i finally succeeded to connect the owl board to the web interface , changin the cable im using to a Beatstep Pro one , also try to get it connected through chromium application.. but still im kinda disappointed that i have to always click shift random record + mod atm random record to get the normal behaviour of the unit ...

I'm sure they will fix it. Maybe i can find another cable and try it with that. Does the board need to be powered seperatly or is usb power enough?

rootapprox commented 1 month ago

yes the module needs to be powered to be detected i guess from my experience

blindorange commented 1 month ago

I think I maybe getting confused about the order of calibration, GitHub says power on first then set pots to 12, the manual switches these around, set pots to 12, then power on, not sure which is correct, what are you folks doing?

pssssssst commented 2 weeks ago

i tried both. But it doesn't seem to make a difference to me. I also tried the new beta, but the reversed cv issue is still present

hirnlego commented 2 weeks ago

@pssssssst try resetting the CV mapping (RECORD + RANDOM while in CV map) then save and restart. Are you using attenuverters instead of attenuators? The latest beta should resolve the problem of attenuverters values saved incorrectly, but they need to be reset.

pssssssst commented 2 weeks ago

I tried that a lot of times. With attenuator and attenuverter mode. But it just doesn't save the configuration.

hirnlego commented 2 weeks ago

And yours CV are reversed regardless of using attenuators or attenuverters?

You could try removing the configuration files:

pssssssst commented 2 weeks ago

Okay, i will try that this evening. Thanks for responding and also for releasing this module. It is so much fun.

pssssssst commented 2 weeks ago

Okay, i couldn't wait :) Your suggestion fixed the problem. Thanks a lot. I'll keep testing further, but so far it seems fine. This solution should probalby be posted as well over on modwiggler.

hirnlego commented 2 weeks ago

Glad it worked! Yeah, when we'll release the new firmware we'll provide complete instructions. Thank you.

@rootapprox try flashing the new beta 2 and delete the configuration files as suggested above, this should fix your problem as well.

rootapprox commented 2 weeks ago

thanks a lot @hirnlego i flashed the new beta and everything works fine , also i can save parameters now and stay persistant after the on/off power cycle.
