calibration

[ello]

Hey there... since i got my nerdseq my modular has been growing. today i faced real bad calibration issues and i'd like to know how you get your modules in tune using the nerdseq. i simply cannot get mine to line up properly.

e.g. the a-111-6, plaits an sofia. all of them give different results when first tuned on a base c-4 for example and than fed the very same pattern. c4 c5 c6... while c4 sets correctly c6 is different on all of the modules.

so i looked into the calibration page on the nerdseq but i fear touching those values. afraid, they don't make much sense to me anyways. for the different channels there are different values for the same notes. hope you understand what i mean here.

so any advise getting me on track again is higly welcome. i got really frustrated today that i just wasn't able to get the simpliest melodies play together.

cheers,
Ello

This sounds like a scaling issue and I don't think the NerdSEQ can account for this. 

Some modules have their own calibration for this but I use a Klavis CalTrans for this exact purpose.

thank you. 

since i am unsure if i changed the calibration values accidentally, is there a table with the original values? i am uncertain about the fact, that there are different values for the same note on the different channels

There is no general table. Each NerdSEQ got it's own table and that the values are different to each other is totally normal. That IS the calibration :-)
Components got always tolerances and so each output got different values. And the calibration is fixing this.

so did i skrew things by adjusting those values manually using a tuner? is there a way to reset this? is this done automatically in the background?

You follow the calibration part in the manual and get it to the desired values again. You need a multimeter and not a tuner for that.
A tuner will only get the results from your oscillators and they might not be calibrated well (or pitched wrongly).

oh well, guess i touched something i shouldn't

You are back in 10 minutes with a multimeter. Worst case you can also ise o’tools or any of these scopes. But a real multimeter is recommended.

That has nothing to do with the NerdSEQ. When different Oscillators have the same pitch at e.g. C4 but differ at C6, then those Oscillators are not properly calibrated.

Consult the manuals of your Oscillators how to calibrate them.

As an afterthought:
If you have an Ornament & Crime module, a Disting 4 or Disting Ex, a Zeroscope or a Mordax Data, you could just measure the frequency that your Oscillators emit. Especially the O_C and the Disting Ex are very usable for this.

If you have none of these modules then maybe you have a smartphone. Both for Android and iPhone exist free apps that are able to measure the frequency of a sound. Just play the Oscillator through a speaker and look at your phone.

today i finally found time to calibrate my nerdseq and it was indeed quite detuned on all outputs and voltages. since i didn't touch the potentiometers in the past i skipped that step.

now it is much better.
