this seems like a way to do some very interesting script-like capabilities...
I think I got to make a sub-forum for that as this is not really I2C related. But answers here for now:
(Things can still change depending on many factors)
- 70 lines
- each line is updates 1000 times/second = 1khz
- order matters, lines are processed in a linear order, wrapping around
- line execution conditions are also involved
Kind of scripting / algorithm is possible.

- Use an envelope with its output on MOD 1
- Then on track 1, use the MOD column to control some parameter of this envelope (say release time), but without messing up the actual MOD 1 output? I.e. the MOD value specified in track 1 only updates the envelope release parameter, but does not actually contribute to the MOD 1 output, which should only be set by the envelope.
Sure that works. But keep in mind that the changing release got direct impact on the MOD output as well.
I actually just did that and it looks quite funny on the envelope curve :-)
Ah wait..didn't read that too well yet. The MOD column will automatically output on the MOD, so that isn't possible anyways.
I did MOD output (which is the output of the envelope) does change the release time of the same envelope.
I think it would be interesting if it were possible to prevent the MOD output from the mod column, especially for cases where the MOD output is used for envelopes. Because, currently, this makes the MOD column unusable.

I don’t plan to change anything in the main sequence mechanism.
You can set variables from the FX columns which you can use within the mappings.

That's indeed what I do now, and it works fine. There are always multiple ways to do stuff with the NerdSeq. That's the great thing about it!

You can always put it into the feature requests.

Wow this is pretty incredible. I am very excited.
RE: I2C Expander - Inkog - 05-25-2023
Any word on when the hardware will be available for purchase? I've been (im)patiently waiting for this since last Superbooth! I don't want to miss them.

I will send the beta-units out in 2-4 weeks and then when the testing is finished. No worries, there will be enough in the first batch I think.
Firmware Release Candidate will also be available around that time

Let me know if you need a beta tester with a few decades experience writing and testing software
I can test everything but IC2, I'm still waiting for another ER-301 production run :/
RE: I2C Expander - geremy - 05-27-2023
So from the large picture on modwiggler and modulargrid, it seems the i2c expander uses a different 3.5mm jack? The plastic internal ones like tiptop has used in the past? Is that just for prototyping or production as well? Is there any particular reason for the switch? Thanks!
