Nerdseq & Teletype (& i2c)

I just bought a Nerdseq which is supposed to have an upcoming i2c expander in the works. As expected the NerdSeq is aimed to be a leader on the i2c bus, but I’m hoping that in the future it might be possible to control some parameters of the NerdSeq using, if not dedicated ops, at least generic ops or maybe even the readily available EX ops? Who knows!

Right now my plan is to get Teletype to control whatever it can via EX.M ops, but there are also the good ol’ CV/Trigger outputs which will pair nicely with NerdSeq’s four available CV inputs.

Teletype is a very powerful module and so is the Nerdseq. Is anybody else rocking both in a single case? Any examples of how you got them integrated? Any upsides/downsides to having both?
Opposing opinions? Overkill? Mistake? Should be avoided? Doesn’t make sense?

This isn’t a “tell me what to buy” thread. I have this notion that these two will make a natural pair, but I don’t remember ever seeing them in a single case. I intend to play each to its strength but truth be told I’m getting really excited with the prospect of having them talking to each other. I would love to hear your opinions about or experiences of such a mind-blowing combination of sequencers.

A final thought:

I use a small bluetooth controller for Teletype scripting. Nerdseq has the option to use a Sega gamepad for programming the sequencer.
I’m thinking … dual player i2c challenge on a live set ? :video_game: VS :video_game:


I have both a Nerdseq and Teletype. I use the Nerdseq for mostly planned sequencing and the Teletype for mostly generative sequencing. The Nerdseq is great for sending triggers over to the Teletype at set times in a track so that the generative stuff can be kept in check. Teletype would probably be good the other way around too, but I haven’t used it much that way.

I wouldn’t get a Nerdseq for functionality that it’s unlikely to have (possibility of controlling it via i2c) at least according to this post I2C Expander This advice goes for anything. Get it for what it can do now and not what you hope it can do down the road, because you’ll end up disappointed if that functionality doesn’t end up getting implemented.


I haven’t decided on a specified way of having the two interact, and I’ve found that it’s best to not pre-decide or settle on a specific way of doing things, even though my natural inclination is to try and organize patches within specific M.O’s. That being said, I am very intrigued by the prospect of having Teletype control those 4 CV inputs on the Nerdseq. The available FX that allows you to fire the clock and reset outputs on the Nerdseq seems like a perfect method of triggering Teletype.

To my eyes the NerdSeq is very similar to Teletype. Like a brother module, with NerdSeq being one or two levels of musical abstraction higher than the Teletype. One could possibly say that the tracker paradigm isn’t than different to scripting using M. So it seems like a natural pair, albeit I’m unsure whether the typical audience is the same, but then again I don’t think it was a coincidence that Teletype has the pattern ops in there!

Thank you for the advice! It was not necessary, as I never hold my breath about updates or promised features, but it was welcomed and appreciated. Funny you should mention though, as I’m notorious for being one of those modular users that pests designers :joy:


Well, it took a while, but my Nerdseq arrived yesterday. It’s time to embark on this journey where these ships collide …

As for the implementation in the NerdSEQ. The upcoming Midi Expander got 2 I2C ports. And they are also on the backside of the module. One port is additional accesible on the front side so you could connect directly like a standalone Atov 16n Faderbox (and possibly others).

Both ports can be either Leader and Follower (formerly known as Master and Slave :foul: ) and they can be configured so one is an Follower but signals can be merged into the Leader part (see as a usecase a connected faderbox where you control one part the NerdSEQ, one part the connected gear while the NerdSEQ is also sequencing into the gear). Follower functions are controlling the NerdSEQ internal functions and more. And the NerdSEQ can control and sequence into it’s I2C output. In the implementation it would mean a I2C track got 6 columns which can be freely used for popular I2C commands and more and a drum-matrix for 16 Triggers. So per track they are many things sequenceable (and don’t forget the patches, FX etc). But I am currently still developing this, so these are the details on paper (and partly already implemented).

I’m unclear about what ‘popular i2c commands’ would be, and what it would take to map Nerdseq’s i2c implementation to the i2c/ii ecosystem for Teletype/Crow/Mannequins stuff. But, as an upcoming Nerdseq owner, it’s intriguing!
