"Compare" button - how to recognize it for MCU controller? any idea?

vladistone · March 16, 2023

I made the small edited version of your lua script "TogglePluginCompareWithMidi" with var discribtion:

local Control = hs.midi.new('SSLnucleus2')

and changed CC number:

metaData.controllerNumber == 79

see full script:

2023-03-16 22:51:28: Welcome to the Hammerspoon Console!
You can run any Lua code in here.

-- print available MIDI device names to the Hammerspoon Console
print(hs.inspect(hs.midi.devices()))


-- Create a new hs.midi object for the desired MIDI device by passing in the device name
local Control = hs.midi.new('SSLnucleus2')
local windowFilter = hs.window.filter
local runScript = hs.osascript


-- AppleScript to click plugin Compare button
local clickCompareButton = [[
  tell application "System Events"
	  tell process "Logic Pro"
        click checkbox "Compare" of window 1
	  end tell
  end tell
]]

-- Callback function for the Hammerspoon MIDI object created above (hs.midi.new)
-- Parameters: object, deviceName, commandType, description, metadata
-- Here we listen for incoming Control Change message that will trigger the AppleScript when received
local handleMidi = function(...)
  local commandType = select(3, ...)
  local metaData = select(5, ...)
  if commandType == 'controlChange' then
      if metaData.controllerNumber == 79 and metaData.controllerValue == 127 then
        runScript.applescript(clickCompareButton)
      end
  end
end


-- Create Window Filter for Logic Pro window
local logicWindowFilter = windowFilter.new('Logic Pro')

-- Subscribe to events when Logic Pro window is in focus (or not)
logicWindowFilter:subscribe(windowFilter.windowFocused, function()
  -- Sets the callback for the Hammerspoon MIDI object when Logic Pro is in focus
  Control:callback(handleMidi)
  print('Logic in focus...')
end):subscribe(windowFilter.windowUnfocused, function()
  -- Removes the callback when Logic Pro loses focus
  Control:callback(nil)
  print('Logic not in focus...')
end)

but I can`t to do anything for control action...

probably is it issue due to:

my MIDI setup have 6 ipMIDI ports for controller connection, but it is not discribed to scrip:

{ ipMIDI 1; ipMIDI 2; ipMIDI 3; ipMIDI 4; ipMIDI 5; ipMIDI 6 }

or may be more any errors I have made in scrip localisation?

after I had changed this var and reload HS:

local Control = hs.midi.new('ipMIDI')

but nothing happens by under MCU control of "compare" button

Hi @vladistone,

You cannot just pass any string to the hs.midi.new constructor like that, it has to be an actual device from the ones returned by:

-- print available MIDI device names to the Hammerspoon Console
print(hs.inspect(hs.midi.devices()))

That's why you get that error:

2023-03-16 23:59:22: 23:59:22 ERROR:   LuaSkin: hs.application.watcher callback: [string "-- print available MIDI device names to the H..."]:40: attempt to index a nil value (upvalue 'Control')

Yes, that's probably why, as those would be virtual sources, not physical devices. So it will probably work when you use the constructor for virtual sources. Use something like the following:

local virtualSources = hs.midi.virtualSources()
print(hs.inspect(virtualSources))

And based on what gets printed to the HS console, you'll be able to choose and set the appropriate ipMIDI port to pass it as a string to the hs.midi.newVirtualsource contructor, something like this:

local Control = hs.midi.newVirtualSource('ip_midi_port_name')

Again, the actual string to pass to this constructor will depend on what you get in the HS console from print(hs.inspect(virtualSources)), I'm guessing in your case it will be just 'Port 3' based on what you've posted above from your MIDI Monitor window.

Be sure to read the documentation on hs.midi here:

Hammerspoon docs: hs.midi

Good luck 😄

J.

Hi @Хорди Торрес

I started to lean the hs.midi and your inform me quite right

but HS console showed me this information:

Hi vladistone,

Try reloading the config again and/or remove the local keyword then save and reload (although for me that variable works as local)?

Hi vladistone,

I don't see anywhere in the snippets you have posted that you are passing the desired port to the hs.midi.newVirtualSource constructor?

Maybe share the whole file as an attachment and I'll have a look.

I haven't had a look at your file yet, bu I just tested sending MIDI from my laptop to my my Mac mini over ipMIDI Port 3, no problem at all. Hammerspoon receives data just fine.

Jordi Torres · March 17, 2023

So,

You have redundant code in your files (for example, my handleMidi function replaces the midiDevice callback, so you don't need that in init.lua), and your init.lua is not requiring (importing) the code from the other file so that code is not being used at all.

See this post for an explanation on how to deal with that (basically you can have all in your init.lua or require the code from another file):

I skimmed through the discussion without downloading the code files. and if I understand you - the essence of this method is in the organization of the "Master" file init.lua with the request for the necessary part of the code from other files of an individually configured repository when certain keystroke events appear...

cool!

What you have right now could be put in the init.lua and be done with it. Since I have a bunch of scripts that do different things I started using the require function to import them into the init.lua depending on which one I wanted to use at any given time (I just comment out the ones I don't need).

Anyway, the files you shared above not only had redundant code but also had typos, but funnily enough, what you shared on the Hammerspoon discussion on Github doesn't contain those errors (because it's basically 99% what I had shared with you initially,).

Have a look at the attachment using the init.lua plus a separate file for the script. ipMIDI stopped working on my Mac mini for some reason so I could test properly but should work.

Good, the idea was to read what I wrote about how to set things up using the require function.

Ok, ipMIDI is working again, not sure what went wrong, and what I shared in my previous post works as expected. Should work in your system too unless ipMIDI craps out for you too 😅

Ah, that. Now I remember you said you're in High Sierra, so then your version of Logic is most likely called "Logic Pro X" and not "Logic Pro" as it's been renamed recently with newer versions.

Glad to hear it's working! 👍

something else is strange - why did my script show the exactingness of the "Logic pro X" process, and you swallow "Logic pro"? perhaps from different versions of macOS?

My first implementation of my own queries:

On 16.03.2023 at 09:33, vladistone said:

how would you implement feedback to match the controller's scrabble strip?

how the behavior of the keys and modification keys too is described (instant action? toggle? track the behavior of the modifier or "Follow key state first" soft-switch? responce for fire-mode?) in general, perhabce all is this determined by the syntax of the functions?...

important for me - recieve a "fishing rod", examples of code injection in LPX!

And I will try to learn how to catch and "fry fish" as needed and the tasks set for myself.

Today I created a send message to use MCU LCD feedback about the information about assigning V-select to the LPX "compare on / off" button:

-- Create message feedback for MCU LCD "compare on/off" (real Device variation)
local midiDevice = hs.midi.new("ipMIDI")
print(string.format("myMidiDevice: %s", midiDevice))
midiDevice:sendSysex("F0 00 00 66 10 12 00 43 6F 6D 70 61 72 3A F7 F0 00 00 66 10 12 38 6F 6E 2F 6F 66 66 F7")

result at LCD into first track column as is:

|Compar:|
|on/off |

MIDI Sysex sends to the MCU midiDevice a string according to the Logic control MIDI Implementation:

Received: <Hdr>, 12, oo, yy, ..., F7 Update LCD
- oo Display offset to write from: 00 thru 37 for upper line and 38 thru 6F for lower line.
- yy Data: ASCII equivalents for display characters written from left to right,
  including line wrapping between upper and lower lines. Up to 100 data bytes
  may be sent in one message.
Transmitted: None

The only thing that does not satisfy is that information is displayed both on the MCU and on the XT compartment (it is displayed simultaneously as virtualControl "Port 1" and "Port 2")
When I trying to assign output to specific one virtual port - "Port 2"

But - with no results...🤔

-- Create message feedback for MCU LCD "compare on/off" for Virtual Port:
local midiDevice = hs.midi.newVirtualSource("Port 2")
print(string.format("myVirtualPort: %s", midiDevice))
midiDevice:sendSysex("F0 00 00 66 10 12 00 43 6F 6D 70 61 72 3A F7 F0 00 00 66 10 12 38 20 6F 6E 2F 6F 66 66 F7")
