I noticed that 1/64 notes in the params is giving me 1/32 timing. Not a complaint by all means just a heads up if anyone else wants to check it out.

alphacactus · 2019-04-12T23:08:16.576Z

thanks for the report I’ll take a look at it shortly here.

alphacactus · 2019-04-26T22:25:04.872Z

alright apologies for taking so long to get back around on this. the midi code is directly ported from awake where I see a similar issue when using 1/64 notes.

code is as follows:

options.STEP_LENGTH_DIVIDERS = {1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64}
beat_clock.ticks_per_step = 96 / options.STEP_LENGTH_DIVIDERS[value]
beat_clock.steps_per_beat = options.STEP_LENGTH_DIVIDERS[value] / 4
beat_clock:bpm_change(beat_clock.bpm)

so doing the math at 32 notes you get 3 ticks per step and 8 steps per beat. at 64 notes you get 1.5 ticks per step and 16 steps per beat. so I think I’m going to have to take a look at the beatclock library to see what’s going on.

hi. hoping for help. meadowphysics used to work, but after installing some new scripts “timeparty, otis updates” it now no longer loads and I get the following error…thoughts?

would still love to have the option to load samples in meadowphysics like you could on Norns 1.0

gnome666 · 2019-06-15T07:05:20.696Z

bumping to see if anyone has any thoughts? i’m outta my league here

okyeron · 2019-06-16T17:31:09.901Z

You could try deleting the pmap/pset files and then reload MP

/home/we/dust/data/meadowphysics/mp_midi/mp_midi.pmap
/home/we/dust/data/meadowphysics/mp_midi/mp_midi.pset

Aha - I just got it to reproduce your error after saving a pset.

steps to reproduce:

in params set output to audio + midi
save a preset to default
reload MP
error happens

So if you delete the psets it should probably work again, but preset saving may be broken if you set output to audio+midi.

@alphacactus should I file this on github?

gnome666 · 2019-06-16T20:18:59.628Z

awesome! thanks…will try and report back

EDIT:

that did the trick. one million thanks okyeron!

thopa · 2019-07-18T15:16:56.612Z

Thanks for porting this to norns!
Im having trouble slaving it to incoming midi clock, other apps do react to external midi clock.
Anything i might be missing?
Cheers

Am getting lots of index errors after the upgrade. Anyone else experiencing this? It just hangs on loading and maiden and sc throw indexing errors…

alphacactus · 2019-09-04T00:35:52.476Z

sorry been away from things for awhile. not going to be able to support development for the foreseeable future if anyone wants to take the reigns for the meadowphysics port.

dansimco · 2019-09-04T01:40:59.655Z

I’m looking for OSS work to contribute to at the moment. Happy to help out. (Edit: Forked, I’ll read back through this thread and file issues this afternoon)

kasselvania · 2019-09-04T01:44:29.395Z

Thanks for this. It’s a wonderful application and I’d be bummed to lose it.

dansimco · 2019-09-04T05:53:52.916Z

Would you like to maintain your repo as the master repo and handle pull requests? I’m working on some updates this afternoon as well

dansimco · 2019-09-04T11:11:20.635Z

Did you get external clock sync working?

thopa · 2019-09-04T11:42:36.244Z

Hi! Thanks for checking,
I think i got it working but my memory aint great,
Ill check later and let you know.
Cheers!

dansimco · 2019-09-04T23:47:09.697Z

I made an issue for this in my fork: https://github.com/dansimco/meadowphysics/issues/2

I’ve been doing some learning-by-refactoring with the script there, and some changes to the ui rendering that are if anything just more to my taste. Will get onto the preset issue first, then probably look at sample playback among more ui tinkering.

alphacactus · 2019-09-05T02:49:04.884Z

here’s the ack sample playing version by the way. it’s from the old dust repo so it’ll need a few updates.

github.com

alpha-cactus/dust/blob/master/scripts/alphacactus/mp_ack.lua


local ack = require "jah/ack"

engine.name = "Ack"

local meadowphysics = require "ansible/meadowphysics"

local g = grid.connect()

local clk = metro.alloc()

function init()
	-- meadowphysics
	-- mp = meadowphysics.new()
	-- save the meadowphysics state using mp:save("filename")
	--mp = meadowphysics.new() -- for default 
	mp = meadowphysics.loadornew("alphacactus/mp.data") -- to load a saved state

	-- set mp.mp_event to your callback function(see step function below)
	mp.mp_event = step
