hi did you ever get this sorted? Ive run into the same issue and I too have never coded. Thanks!

135

I deleted we via maiden then reinstalled, that did the trick.

since the most recent Norns update it seems im getting an error init upon loading the kr rings script. It does actually load but I do not have any control over the script. Does this need to be updated or?

137

Yes, you should update both awake-rings, and we from the Maiden package manager.

And if you’re still having issues after doing that, try a sleep and restart, and then DM me the error that appears in Maiden.

I had to redownload the we folder to get the most recent version of the karplus engine. That should do it.

I just recently remembered that I can use an ornament and crime running hemispheres as a usb midi to cv interface (and vice versa). I have really been enjoying using Awake to sequence a single modular voice. Last night I realized that I was only using 2 of the 4 cv outs to do this, and was wondering if there is a way to get 2 voice polyphony by trading midi channels per step. I’m happy to give it a go but don’t know where to start.

I guess my first question is how crow & JF ii handle this? Is it on the norns side or the crow side of things? I don’t have either, so I’m not clear on it (a crow is in my future). Is it a sort of round Robin, each new note is sent to a new voice? Does it cascade as decay settings get longer? Does that mean it happens on the JF side?

A run through the studies is probably a good place for me to start after some coffee…

I don’t know much about the technical implementation, but yes it appears to be a round robin handled on the crow/JF side. All the norns script does is send crow a command to play a JF note.

For trading midi channels per step you would do this in the norns script though. You’ll need to add an additional midi channel parameter (since currently awake expects only 1 channel), and then keep track of the “active” midi channel in a global variable. Then any time you send a midi note on you could send it to the “active” channel and flip it between channel 1 and 2, for example.

What @crim described above is probably all you’ll need for Awake, but if you want a “least recently used” voice stealing algorithm, Norns comes with a really useful little library called voice: https://github.com/monome/norns/blob/master/lua/lib/voice.lua

… I’m having a strangely hard time finding an example of it in use, but the principle is something like this:

local Voice = require 'voice'

local voices = Voice.new(2) -- 2 voices of polyphony
local midi_out = midi.connect()

local function start_note(note, vel)
  -- allocate a voice, "stealing" an existing one if necessary
  local voice_slot = voices:get()
  -- use the voice ID (1 or 2) as the MIDI channel
  local midi_channel = voice_slot.id
  -- send MIDI note
  midi_out:note_on(note, vel, midi_channel)
  -- tell this slot to send the correct note off when the voice is released or stolen
  local release_callback = function()
    midi_out:note_off(note, 0, midi_channel)
  end
  slot.on_steal = release_callback
  slot.on_release = release_callback
end

then you can use that start_note() function to send MIDI notes each step and they’ll alternate between channels 1 + 2, but if you call voices.slots[1]:release() between steps, a note off will be sent on MIDI channel 1, and the next step’s note will always go out on channel 1, while voice/channel 2 drones. Maybe not that interesting for steady 16th note sequences, but it’s really useful for grid or keyboard interfaces, and it’s a good way to make sure you’re sending note off messages.

any chance in a future update ta have clock input from crow?

145

we’re working on a “global clock” module (for the entire norns system) which will have a configurable source including crow. so yes!

but in the meantime, adding a crow-clock of awake would be a pretty straightforward modification after reading through the norns and crow studies.

:raised_hands: @tehn amazing! that is good to know!
I don’t mind waiting, it’s not a problem :slight_smile: I’m doing the teletype studies and I can’t handle more studies right now :sweat_smile:

147

i hope “global clock” will have all the MIDI clock needs!

Which CV jack does the clock out occur when using crow?

149

output 1, here you go :slight_smile:

Anyone else trying to use crow outs 1 and 2 but also wanting to send clock?

is it possible to get clock out going out of output 3 instead of 1 for those of us that don’t have just friends yet? :slight_smile:

151

Yes I’ve definitely had the same thought of wanting crow outs plus a clock out.

I think I’ve done this.

It was as simple as changing a single variable I’ll look at the script when I’m not at work.

I changed mine to output 4. Its super easy if you want to try yourself?
In maiden load up the awake script and check line 196

if params:get(“crow_clock”) == 2 then crow.output[1]:execute() end

Change crow.output[1] to what ever one you want so it should read

if params:get(“crow_clock”) == 2 then crow.output[4]:execute() end

Then hit play script to try it out. If its all is good then save it.
Thats what I did seemed to work fine and I’m a complete noob.

Good luck!
