The dream was to have lots of knobs that feel like they’re analogue, encoders often aren’t much fun because of their low resolution and are also quite expensive.
The coolest thing would be endless analogue knobs, read out cleverly to be used like high resolution encoders - which is what I think NI did with their KOMPLETE KONTROL series.
I have a M32 and I’m sure these knobs are digital. Does something like a „endless analog knob“ even exist? I’m curious how that would work…
Don’t know… It was my conclusion because they have 128 steps in one turn and feel smooth… also got the M32 recently 
Maybe they just have a very high resolution…
I thought it must be a potentiometer with the ends close together to have a 360 movement and clever firmware to calculate the output.
It seems they are 360 potentiometers indeed, as well as on the NI Kore and Akai MPD 218.
Apparently they work with two or three overlapping regions.

Damn… I want a MIDI controller with 64 of those… wonder why there still are no products like that…
Just stopping by to report that I have successfully tested 14-bit MIDI CC with MIDI-CAT building the v1-dev branch – it worked flawlessly, thank you very much @stoermelder! Also very excited that 14-bit MIDI will be part of Rack v2.
Perhaps of interest for those building their own MIDI controllers: Here is a great blog post that outlines how to use 14-bit MIDI with Teensy. The 3.2/3.5/and 3.6 versions of the board support 13-bit ADC readings and the associated code upscales to 14-bit. Apart from that, it uses the ResponsiveAnalogRead library which significantly reduces noise/jitter. My breadboard experiments with this worked out great so far.
That sounds very good.
So you get stable readings with more than 10 bit resolution? (I don’t believe you 
please show some proof on a youtube video and tell how you did it)
The ADCs on the Teensys are actually even 16 bit… but since you can never get that stable because of the noisefloor they advertise it as “up to 13 bit” - which is probably under laboratory conditions.
If I could have 12 bit I would be completely happy, as this marks the threshold where it’s no longer possible to move a knob to an exact value. But for me, I got 10 bit at best, and it was more stable on an Arduino, which has only 10bit ADCs to begin with.
Yeah, when I was looking at it all the arduinos looked too crude. The expert sleepers Disting is accurate to 16 bits, so I used that. my (old) stuff is here: GitHub - squinkylabs/thisthing: Alternate firmware for disting
You mean it’s interesting to look at for a MIDI controller? 
well. don’t know. If a very good eurorack module, but it would not be a good thing to build into a controller. It’s basically a 32-bit PIC with a few channels of 16 bit A/D and D/A.
I’m not going to make a YT video. While it is possible to get successive readings moving in steps of 2 on [0, 2^14-1] that is super fiddly and doesn’t work out in a stable fashion. So yes, the effective resolution currently is lower. Perhaps this is because I’m not able to manage turning the pot (Song Huei RK1114N) in small enough movements (a bigger knob might help?) but probably also because everything is just on a breadboard atm.
One thing that is for sure: It’s much more pleasant controlling e.g. the frequency of a VCO with this setup. Changing the frequency of a VCO feels smooth rather than jumpy 
Yeah when it works it’s super smoothe… 10 bit are actually quite nice already… but even then I had to do a lot of smoothing and it might jump a bit sometimes just from moving my hand near a cable or from the (very cool) rgb leds I installed changing color…
I wish there was a solution with higher voltages, I imagine if the Teensy ran the ADC on 12V the fluctuations should be much smaller in comparison… I still wonder why no hardware manufacturer has come up with something really smooth, but seems it’s really not easy or too expensive.
As long as it’s just a few knobs 10bit should be no problem though, but I wanted a lot of knobs and then it got more and more unstable…
Dirty USB-Voltage is another big problem… so if you use a really stable DC-supply everything might get a lot better…
Did this get pushed out to the current release? I don’t see it in my menu. Or maybe the encoders on my device do not support 14-bit resolution …
If not, the slew limiting is an OK compromise.
It is included in the current development build, it is not available in the version in the VCV Library yet.
Quick writeup of using MIDI-CAT v1-dev with 14-bit hardware over here, to be supplemented in a new thread when I have a little more time to experiment. The upshot is that it works extremely well and is easy to set up.
Nice!!!
I have been attempting to use both Stoermelder midi-cat (dev build) and Studio Six Plus One Zilah with Behringer BCR2000 which I edit with mountainutilities.eu
for some reason which eludes me both modules pick up the controller as cc6 which then does work as 14 bit controller but when I try to assign other controllers with different nrpn address (cc99=22 in this case) they are also picked up as cc6 .(or as cc98 which is no good…)
what kind of message do both modules expect to be able to assign different nrpn addresses to different knobs and have them picked up like so ?
it may have been mentioned earlier in the thread but in a way too arcane for me .
I can only speak for Zilah, @stoermelder may have handled the case differently. The MIDI 1.0 spec allows for 14bit controllers, these are on cc-0 to cc-31 for the MSB, and CC 32,to 63 for the LSB. This gives a total of 32, 14 bit CC’s per midi channel.
So the first controller should be cc 0, 32, the second cc1,33
I hope this is of some help.
oh I see its midi cc 14 bit not nrpn 14 bit(at the BCR setup) , its working ! now I just need to figure out proper resolution (turn value).
many thanks for your kind support.

I can only figure out how to do 7 bit in “CV > MIDI-CC” in Rack 2 [free|pro]
