How did you set that up?

#629

I think @zebra just meant use the menu system on the device. reloading a script becomes muscle memory during debugging

that said, the command line version of maiden could be revived. the old version uses IPC which was in place before we moved to websockets

but you can also just execute matron directly as mentioned but there is no readline

#630

Bringing this back up after nearly a year + away from Lua if anyone has ideas!

I wrote a basic screen line wrap function a long time agoā€¦ Iā€™ll try to dig that up again this afternoon.

@Olivier check out the stuff in my HID-demo - thereā€™s a textwrap() function there which could get you going.

Can anyone point me toward some patterns for midi controller integration/parameter mapping? I got a 16n faderbank lately, and I think enough norns users have one that Iā€™d like my app to have ā€œplug-and-playā€ support for that device, but I donā€™t know if there is prior work on that.

Iā€™m thinking it would look something like a parameter with a midi device selector, but still wrapping my head around it.

I donā€™t have a 16n, but I think you just use the parameters menu to midi map faders to control type parameters.

So supporting midi devices like knobs and faders is really just about making your params control types.

I tried implementing the generate_scale function today for the first time, but I only got halfway there in my amateurish attempt. I added a require for musicutil, and then implemented this as a test (along with a note variable and the midi_to_hz function):

scale = m.generate_scale(0,"minor",2)

This is doing something (sounds like a chromatic scale), but changing the scale type ā€“ minor, major, aeolian, etc. ā€“ doesnā€™t seem to have any effect. Is there something obvious Iā€™m missing?

#636

it might be case sensitive (Minor) or some other kind of case error with music util, i vaguely remember messing that up a lot

Hi,

I need a hand with something. I would like to draw the waveform of the audio recorded in softcut via softcut.rec(1,1). Is there a simple way to do this using the core libraries?

#638

no, there isnā€™t. it needs implementing thumbnails on crone side for starters

(or, switching to shared memory or some other IPC layer that is more efficient than OSC)

#639

thanks for the fast reply.

Iā€™m trying to make a lib that will impersonate a grid (with data from OSC)

Soā€¦ How can I emulate a grid key press from a script/library?

Seems like I need to make my own version of norns.grid.key = function(id, x, y, s)
I have x,y,s values but Iā€™m confused looking at the grid.lua source on what happens in the norns.grid.key function.

Any pointers?

#641

just call norns.grid.key normally?

that is what the C layer does when it handles a keypress from libmonome

ed: nevermind let me think of a real answerā€¦

#642

Hmmm. I tried that and thereā€™s no grid, so it errors:

lua: /home/we/norns/lua/core/grid.lua:187: no entry for grid 1
stack traceback:
	[C]: in function 'error'
	/home/we/norns/lua/core/grid.lua:187: in field 'key'
	/home/we/dust/code/oscgrid/lib/oscgrid.lua:31: in field 'key'
	/home/we/dust/code/oscgrid/lib/oscgrid.lua:17: in function 'core/osc.event'
	/home/we/norns/lua/core/osc.lua:87: in function </home/we/norns/lua/core/osc.lua:82>

I figured Iā€™d need to make a copy of norns.grid.key that does not assume a grid is connected

#643

yes, or spoof the device pointer provided by libmonome and stored in the lua Grid class

viz., call grid.new with your virtual device and a made-up id/pointer

you would also need to glue grid.led differently

#644

With Grid.new (or norns.grid.add) Iā€™m not sure what to use for dev thoā€¦

(canā€™t seem to create userdata table from lua)

yeah - I didnā€™t get that far yet. :slight_smile:

#645

Feels super hacky so far but I got something working to hijack grid key presses:

and then also LEDs

Also - made a repo for the work so far - I could really use some help to clean up the library part of this. https://github.com/okyeron/oscgrid

Any recommendations for tools to format lua and supercollider scripts? Maiden makes it difficult to tell where you have spaces and tabs, which makes the scripts hard to read when I open them on other machines.

I wrote a small script that just uses expand to make sure the spacing is consistent. Iā€™m wondering what other people do.

Iā€™m considering moving to just use emacs for everything, and letting emacs do the formatting, but from what Iā€™ve seen elsewhere, it seems like the supercollider support for emacs is kind of rotted. lua-mode for emacs is good.

The supercollider IDE does a reasonable job, but Iā€™d prefer something I can run from a terminal.

Iā€™m working on an adding an earthsea page to mlr. Iā€™ve got it pretty much all the way there but Iā€™m trying to get the pattern recorders to watch and play back presses on the keys page. I can get the patterns to count key presses but nothing plays back. If I add something like e={} e.i=i e.t=eNOTE event(e)
I get an error

Summary

/home/we/dust/code/mlr/malarkey.lua:960: attempt to compare number with nil stack traceback: /home/we/dust/code/mlr/malarkey.lua:960: in global 'grid_note' /home/we/dust/code/mlr/malarkey.lua:155: in global 'event_exec' /home/we/dust/code/mlr/malarkey.lua:78: in global 'event' /home/we/dust/code/mlr/malarkey.lua:976: in global 'grid_note' /home/we/dust/code/mlr/malarkey.lua:947: in global '_gridkey' /home/we/dust/code/mlr/malarkey.lua:318: in field 'key' /home/we/norns/lua/core/grid.lua:183: in function </home/we/norns/lua/core/grid.lua:174>

If anyone has a moment to look over this code I would really appreciate it. Iā€™m sure itā€™s a pretty simple fix, i just donā€™t really know what Iā€™m doing
The relevant lines are around 154 and 959

Great to see earthsea part of mlr :slight_smile:
