I’d also be interested!
Wouldn’t it be easier to share the join link here?

glia · October 13, 2020, 10:08pm

can you share more info on this ? sounds interesting but not sure what the focus is

tyleretters · October 25, 2020, 3:10am

we meet once a week and share what we’re working on. get photobombed by our pets, talk about lua, and just hang.

mo_o · October 29, 2020, 9:22am

Is it planned the next appointment?

EDIT EDIT: we’re meeting via discord video tomorrow (saturday) at noon central! it is a beginner/n00b day so come with any and all questions, ideas, or conversation topics!

EDIT: our next study group meets in about 2 hours! you are invited. link up above Discord Norns Study Group - #27 by tyleretters

the study group convened for the first time in 2021 today. we ended up spending ~4 hours mob-coding a supercollider patch together. use at your own risk!

Same link , Same time, we are meeting again , i am hosting again feel free to join in!

infinitedigits · March 21, 2021, 3:11am

next meetup: Saturday, March 27th, at 10am PST

i’ll be hosting the next norns study group. next week the theme will be: tone to drone in 60 seconds.

the plan is dip six toes into supercollider to make a drone and then dip the remaining toes into norns to put that drone into dronecaster. depending on the group we may opt to mob code a single drone, or you can follow along and make your very own drone. in any case, this is a really great way to get introduced to the norns ecosystem (supercollider + scripting).

any and all are encouraged engage at any and all levels. feel free to come with zero knowledge and ask questions (there are no stupid questions. period.). or feel free to come and just listen to drones (midding is encouraged). or feel free to come with a drone in hand and ask questions about it. or feel free to ask questions about anything else.

if you are interested in making your own drone right away, checkout the tutorial. but please - feel free to ignore the tutorial right now - its mainly for reference.

Blit · March 21, 2021, 11:18am

Great! Its in the same discord link that has been posted before?

Zifor · March 21, 2021, 11:22am

Yep https://discord.gg/SPnEwh55 link expires in 7 days

SMesquida · March 22, 2021, 10:25pm

What are the requirements for this Norns study group? Computer + Norns? Any software requirements? Should we have Supercollider installed? Confirm assistance?

tyleretters · March 23, 2021, 12:57am

curiosity & courage! come on by

infinitedigits · March 23, 2021, 2:44am

no norns required! though we might at some point go over how to insert drones into dronecaster (on norns), the supercollider bit will be norns-independent. it might be helpful to have supercollider installed if you want to follow along with that in realtime, but I plan to have a doc that will mirror what we do you can easily sit back and enjoy the show (and ask any questions that come to mind). no confirmation needed, just pop in!

tyleretters · March 27, 2021, 4:53pm

our “tone to drone in 60 seconds” event is starting in a few minutes! come on by
