A simple horizontal sequencer would not be hard to build, and probably a great first norns project :wink:

Once you get into things like setting note length and accessing notes beyond a single octave it gets a little more complicated, but I think mostly in terms of UI. Figuring out how to interact with more ā€œadvancedā€ features is part of the challenge/fun of working with the limited interface of only an 8 by 16 grid and a couple norns encoders.

Its been said before, but I highly recommend people check out Kria if they havenā€™t already. It can be traditional or quite deep and complex. I havenā€™t played with the norns version much, but IMO the ansible version is one of the best sequencers in eurorack.

has anyone else thought about a port of asl for norns (no crow required) ?

the c layer stuff would need to be ported to lua (I assume) but perhaps itā€™s doable ? seems like it would be a great pair with r engine

I think Fugu is the closest one to this that Iā€™ve used. It has some cool additional features (multiple playheads that can run in different directions and at different speeds), but at itā€™s most basic itā€™s a polyphonic piano roll

the idea of importing the asl lib for general script use has been floated a bit ā€“ especially watching trentā€™s livestreams, this would be awesome for more than just envelopes!

totally off-topic, but the ER-301 seems perfect to be able to handle thisā€¦only reason I mention is that I have a sense of how I would set it up on the 301 but have no clue how to code :slight_smile:

Thank you for the response!

I had already tried most of the sequencers that youā€™ve mentioned, and none of them scratch my particular itch. Iā€™ll go ahead and describe in more detail what Iā€™m after in the paragraph below.

I am looking for a way to punch in full chords step-by-step, that will then be played back in a loop. For example, maybe I have a simple chord progression I want to loop over a 9/8 bar - I would want an interface to punch in a chord on step 1, move over step 4, enter a different chord, move it over to step 5, punch in another chord etc. Of course, rests and held notes would be a thing thatā€™s possible. After punching in all the chords in a loop of 9 (or multiples of 9 for loops over multiple bars), it would play it back quantized and I could record it in the tape for use in a track.

Iā€™ve only had cursory looks and tests with the sequencers youā€™ve mentioned above, but thereā€™s nothing exactly like this Iā€™ve found.

Sorry if Iā€™ve been a bit unclear, but generally I find that the step sequencers Iā€™ve seen in norns are ā€˜horizontalā€™ - you punch in melodies to a number of steps, and any polyphony would be the result of two or more tracks of melodies playing simultaneously. Iā€™m looking for a ā€˜verticalā€™ approach to sequencing - each step is not just one note but an entire chord voicing (with up to whatever polyphony is supported in norns), with a fixed loop length. There would just be one track, but each step will contain information of an entire note group.

Unless Iā€™m hugely mistaken (or it already exists), I think this should be doable and I might dive in and try to write a quick sketch for the basic premise and develop this from there.

Not gonna be exact, but reading your description, cranes does a lot of this

Iā€™d love to hear about it if you would like to explain a little more! Do you have a codebase or something I could check out? Iā€™m new to lua and the norns environment overall and Iā€™d love to hear about some challenges I might not foresee if I do embark on trying to make this a thing.

#672

I tried that briefly but was slightly frustrated with it. Will revisit it when Iā€™ve become even more familiar with the grid, it was probably just me not being comfortable enough yet.

#673

Let me know if you want testers or stuff. Iā€™d be all over this if this sequencer existed.

It was a fairly direct port i attempted whilst borrowing an OP-1 from a colleague. I think the hardest thing for me was trying to get swing as a parameterā€¦ Iā€™ll check out the code over the next few days and let you know

Would it be possible to create Druid as a script for Norns? Apologies if this has already been done, and therefore that this is a dumb question, but Iā€™m just starting out with Crow.

I donā€™t really want to have to have my computer sitting next to my modular (in general I find having a computer around kills my ability to create for some reason). I have my norns plugged into crow and it has a screen and USB support, so it would be awesome to simply plug a keyboard in and talk to crow directly that way.

Is this doable/done already?

#678

Maybe worth a mention but the keystep sequencer is pretty much 4-note Endless in a Midi / CV keyboard. Itā€™s not as pretty and you will need to count in your own head, but itā€™s all there if you just want an endless sequencer.

Or if anyone wanted to figure out a minimal UI for porting.

A novice question. Has anyone tried implimenting the PI 7 inch touchscreen/LCD Screen with DIY norns?
Would it have any advantage? or a fun diversion? I am currently waiting on a few parts on my DIY Fates and i just finished a compute module cradle for a work project with a 7 inch touch screen and was thinking about slamming together my own Faux Norns with a big screen.

#680

Thank you very much! Iā€™m seeing if I can put together something simple first and develop it further, and maybe I will use it as a reference.

#681

Iā€™m working on a new sequencer for Norns + Grid. In terms of UI, would you want to be able to select any notes across multiple octaves, or would choosing from a set of chords be enough?

#682

IMHO no real advantage, but maybe a fun diversion.

Probably good to go read the norns on raspberry pi thread with regards to this kind of hacking.
