I've had my o_C for about a month now but only just trying it since it needs quite a bit of learning I needed some dedicated time.
Having an issue with the CV out, I'm using copiermaschine but the CV is v. high. I'm only getting about 2 octaves and have to have it set on either -5 or -4 octave to get any playable cv into my oscillators. note the octave settings range from -5 to +5.
my oscillators are tuned as low as they will go. It's not a very usable situation atm. has anyone else also got this issue?
I don't have a multimeter so i skipped stage 3 - "calibrate DAC channels"
At 'calibrate CV inputs' -
with no signal connected to the inputs, twist the right encoder so that the value shown is as close to 0 as possible. There may be some jitter and it might jump around between -1 and 0, or between 0 and 1 — that’s fine — just get it as close to zero as possible. when done, click the encoder to move on / repeat for all remaining CV inputs.
I found that each CV input was at something like 1700 by default so adjusted them all down to zero - lots of encoder turning!
Adjusting the CV input scaling - again, no multimeter, but i took it on trust - connected a cable from A out to CV1 in and long press the right encoder to set the offset value.
As far as i can tell the module is now working as it should be!
Ah great, I'm glad it worked for you too! Maybe this is something we should put on the wiki page (as well as a note about how to change the encoder direction) as these seem to be common queries and o_C is complex at the best of times. Not sure who is in charge of the wiki though - admin?
I think you're right, it would be good to inform folks they should attempt the calibration at least once - it's not hard. I did use my multimeter and it seemed like all the settings were out by about the same amount.
There's so much to learn about the module too. I'm finding the original O_c wiki/docs a bit confusing as they're a bit terse and assume people must know parts, like how the CV3 changes the mask rotation on the Copier Maschnie - I can't work it out... It's such a deep module. It's really good though
Don't have multimeter and don't really want to buy one. I guess I should. Might need to put a disclaimer on the shop page as well that it needs to be calibrated... Mine went back as it had other problems. Hopefully it will came back calibrated 🤞.
Hmmmmm. I hadn't performed any calibrations and I was able to get decent results by reducing the input gain (by default it's at 1.0, the max), and lowering the cv output by 2-3 octaves. But I bet I can get better results with this calibration so I'll try that. Thanks for the info!
