Clocking alternatives

[XORadmin]

I dare oppose you since my experience is that audio is far more reliable using Bitwig and Ableton compared to midi. As I understand it the audio process has a higher priority since it needs to be real-time ti avoid clicks and it  gets updated more often than midi in the computer. Correct me if you can. In my case I use a beefy MSI PC with Win 10 and a minimally populated test project in Bitwig 3.

1. Do you still have the option to program the Nerdseq to recognize positive voltage clocks? If so then please do that. It will make a huge difference for a lot of users. 

2. I use a Motu 8M with DC coupled outputs. Most audio interfaces have DC-coupled headphone outputs so most nerds can use those without hassle.

3. Sure but isn't that a hypothetical problem? DAWs are known for extremely low noise floors and I clock nearly every other module in my system this way.

"If you have a normal good Midi or 24ppqn or 1/16 clock source, the synchronising will be perfect. If not, then the source is the problem."
I think your perspective might be a tad restrictive. If the device can't comply with the context it is made for (from a user perspective) the design is incomplete. Please read this in the right way, I'm still amazed by Nerdseq. Adding options that contribute to ease of use and flexibility is a very intelligent way to go since eurorack has so many possibilities and therefore has a greater number of outlier scenarios than a more homogeneous context (NES f ex, no modularity and perfect compatibility). We are a rowdy bunch with very different setups.

The usefulness of having multiplication options for clock in, out and reset seem self-explanatory to me. Using them you can  alter the role that Nerdseq occupies in a system and lets you use it in more links of a clocking chain. It's much better to make a module that fixes the idiosyncrasies of other modules that require this-or-that clock input/output or has some fixed gate length or whatever.

Using audio to clock is only a workaround in the music world since the USB handling of non-realtime operating systems (and lower USB types anyway) is not good enough for stable clock production. As you didn't mention before what system you use, i assume a normal soundcard audio output. But even with DC coupled outputs, you got to produce the good voltages and clocks/resets/run for either DINsync/sync24 (best) or for 1/16 clock (2nd best because it needs to multiply the incoming clock which is always worse than the real clock).
The noise floor of the DAW is not interresting, more interresting is the noise of your computer/soundcard and these can indeed lower the signal quality.
I don't know how well your setup is, but if you are able to produce the valid signals following the specifications, then it should work perfect.

NerdSEQ has digital inputs and outputs and can detect 0 and 5 Volt levels (within the hysterisis) and it will run perfect if using the mentioned clocks or midi. 
The clock in and outputs included in the NerdSEQ are standards since decades and comply completely within the context Eurorack and beyond.
If these are not what you need, then you need to multiply or divide your signals yourself. In the world of eurorack this should be one of the more easy tasks. In the world of computers the same.

I don't agree that the design is incomplete if something is missing for a minor amount of users. There is and will always be anything that someone is missing. The key is in the importance / priority of functions for many users and I prefer to concentrate on functionality that can't be easy or not archieved externally. Clock dividing/multiplication for inputs or outputs is not an important feature on my list. It is interresting per track and that is implemented. It's still a sequencer and not a clock divider or any other tool even if you can do a lot of that stuff with it, too.
