IIRC i just tried to clic on the Background scripts/Settings button. Then the “Plugin is loading …” message appeared.
OK. I can’t see that in the log, meaning that the plugin crashed before that. The very last log entry is that it starts the OnInit function for background script 2. What does that function do?
Log:

It seems that something is not working as expected with the port configuration actions in background scripts.
I have four background scripts. I have added an init event with ports action configuration to this four scripts, like this:
Background Script 1: (init) {outputport:GP1} {inputport:GP2}
Background Script 2: (init) {outputport:GP9} {inputport:GP10}
Background Script 3: (init) {outputport:GP5} {inputport:GP6}
Background Script 4: (init) {outputport:#none#} {inputport:#none#}
Steps to test this issue:
- I set manually all the ports of this four background scripts to ports GP11 and GP12
- I click the “Run(init)commands“ button of Global Settings/Background Scripts of every script
- The ports changes as expected. It is working well
- I set manually again all the ports of this four background scripts to ports GP11 and GP12
- I quit the Stream Deck editor
- I open again Stream Deck editor
- The ports of the background scripts remain GP11 and GP12, they have not changed according to the port change actions of their (init) events
Step 5,6 - Do you mean “Stream Deck editor” or “Stream Deck software”? Init commands are not run when you open the editor.
Here is the code for Background script 2:
/// <reference path="C:/Users/LPA/AppData/Roaming/Elgato/StreamDeck/Plugins/se.trevligaspel.midi.sdPlugin/ScriptJint/streamdeck-midi.d.ts" />
// ------------------------
// Control Change mapping (same style as sysExList)
// ------------------------
const ccList = [
// Decrease channel (-1) as compared to midiscript
[1, 27, "g_dev_on", 0], // Device On/Off
[2, 0, "g_t_img_idx", 1], // Selected Track : Index for selected track image, based on Mute, Solo or Arm status
[2, 1, "g_sb1_img_idx", 1], // Index for session box 1 track image
[2, 2, "g_sb2_img_idx", 1], // Index for session box 2 track image
[2, 3, "g_sb3_img_idx", 1], // Index for session box 3 track image
[2, 4, "g_sb4_img_idx", 1], // Index for session box 4 track image
[3, 0, "g_tb", 9], // Twister Bank
[3, 1, "g_sr", 9], // Session Record
[3, 2, "g_sa", 9], // Session Automation Record
[15, 0, "g_trackNum", 0], // Track Number
[15, 24, "g_sceneNum", 0] // Scene Number
];
// Fast lookup for CC
const ccMap = Object.fromEntries(
ccList.map(([ch, ctrl, name]) => [`${ch}_${ctrl}`, name])
);
// ------------------------
// Initialization
// -------------------------
function OnInit() {
ccList.forEach(([ch, ctrl, name, init]) => {
gvar.set(name, init ?? 0);
});
}
// ------------------------
// CC handler
// ------------------------
function OnControlChangeReceived(channel, control, value) {
//console.warn(`Received CC ${channel},${control},${value}`);
const key = `${channel}_${control}`;
const varName = ccMap[key];
if (!varName) {
//console.warn(`No variable mapped for CC ${channel},${control}`);
return;
}
//console.warn("BCC seting variable:" + varName + " from " + gvar.get(varName) + " to " + value);
gvar.set(varName, value);
}
I’m afraid that since OnInit() intializes some variables, it triggers things elsewhere.
If you haven’t reverted to the previous version yet, could you please change “level2” to “level3” in the EnableLogging.txt file and restart the Stream Deck software. Then we will have more details about the variable handling.
When I say “Stream Deck Editor” I mean the app “Elgato Stream Deck“. This:
I use the name “Stream Deck Editor” to differentiate it from “Stream Deck Device”.
Regarding the steps 5 and 6 posted before: you will get the same behaviour if you change steps 5 and 6 to this:
5. I unplug the usb cable from Stream Deck device
6. I plug the usb cable again to Stream Deck device
By the way, when the (init) events of the background scripts are executed?
For me, “Stream Deck Device” is of no interest. When you connect/disconnect a device, just about nothing happens; all buttons and dials remain loaded in the Stream Deck software, and you can still edit everything in the editor.
The important difference is “Stream Deck Editor” vs “Stream Deck Software”. If you open/close the editor (i.e., the window), nothing happens besides the window opening and closing. When you restart the Stream Deck software, “everything” happens.
Init events are executed once, when the script is activated. This is:
- When the Stream Deck software starts, and the plugin is started (i.e., when the plugin is started, not when a button is loaded). Unless you manually perform one of the actions below, this is the only time they are executed.
- When you load a new script as a background script.
- When you check the checkbox to activate a background script.
- When you press the Run Init button.
Done with the new version.

I write again the steps 5 and 6:
- I quit the Stream Deck editor: it doesn’t mean that I close a window, it means that I quit the app (or I quit the software)
- I open again Stream Deck editor: it means that I launch the Stream Deck app that was quitted in the previous step (or I launch the software)
What does background script 1 look like?

// ===================================================================================
// SYSEX TYPES - SUMMARY
// ===================================================================================
// Each entry consists of prefix:p, and index, i and a configuration map (dictionnary).
// Each entry indicates how to process received Sysex messages with the byte layouts:
// noIndex : F0 p [slot] [control] payload F7
// indexed : F0 p i [slot] [control] payload F7
//
// Configuration maps are made of :
// 1/ type: A given type among the following :
// - String : Raw ascii conversion
// - Chunked : A string that arrive in several parts (chunks) with a 1st control byte first
// - Array : An array of string that arrive in slots 1st and chunks with a control byte 2nd
// - Vector : One or several numerical values directly fed from the sysex byte
//
// 2/ The global variable name: varName or (for vectors) a variable array (VarNames) in which to store the received content (payload).
// For arrays, varName will be fed as an array of received values.
//
// 3/ init: The initial value of the variable or (for vectors) and array of initial values
//
// 4/ hook: The name of a function to be called before variables are updated, for example to perform extra calulation of transformation.
// Variables are passed by reference to the hook, enabling transformation before update.
// A hook can return a "false" value, in which case the update of variables will be bypassed.
//
// All entries support both noIndex [p, {configuration}] and indexed [p, i, {configuration}] entries.
// A given prefix p must be used exclusively as either noIndex or indexed, never both
// For noIndex entries, the payload starts 1 byte after the prefix (offset = 1 base).
// For indexed entries, the payload starts 2 bytes after the prefix (offset = 2 base).
// The slot (for arrays) and control byte (for chunks) add +1 each to the base offset when present.
// The chunk control byte is made of two parts : 1st part; chunk nubmer, 2nd part: total number of chunks
//
// -------------------------------------------------------------------------------------------------
// type | ascii | noIndex layout | offset | indexed layout | offset
// -------------------------------------------------------------------------------------------------
// string | yes | p, text | 1 | p, i, text | 2
// chunked | yes | p, control, text | 2 | p, i, control, text | 3
// array | yes | p, slot, control, text | 3 | p, i, slot, control, text | 4
// vector | no | p, numerical values | 1 | p, i, numerical values | 2
// -------------------------------------------------------------------------------------------------
// Notes:
// - string and vector share the same offsets (no slot or control byte)
// - chunked noIndex offset (2) differs from indexed (3) by the index byte only
// - array is the only type carrying both slot AND control bytes, giving offset 3 (noIndex) and 4 (indexed)
// - ascii conversion (decode()) is used for string, chunked and array
// - vector values are raw numeric bytes, no conversion
// - vector can have only one entry to p^rocess a single variable

I’m struggling to understand why the latest version has caused these issues. I can’t recall having made any changes in the areas you report, so my current theory is that it is a timing error of some sort.
I can reproduce the issue reported by @jordikt, but haven’t found the cause yet. I’m unable to reproduce the issue reported by @thx538, but I haven’t had time to test with bg script 1 yet.
I apologize … what I posted just above is the the background script #3.

and I have only 3 background scripts.
I reverted to Version 4.2.0.133 for the moment.
Let me know if you need further testing.
Log ID:
f5c41eb3-b8b2-4aa6-b917-71d8c0cbaa66
Video:
Log should describe the behaviour shown in the video.
Everytime I restart the Stream Deck Software, the ports of the background scripts are configured to ports GP11 and GP12 (the ports that I manually put for testing).
Once the Stream Deck Software has been launched, I press the “Run(init)commands“ button of every background script. They are set to the correct ports.
But when the Stream Deck Software is quitted and launched again, the ports are restored to GP11 and GP12.
And also a little annoyance.
It seems that in javascript, in midi.sendCC the channel is is 1 based while it is 0 based in OnControlChangeReceived.
Am I correct ?
Do you think that should be changed while we are still in a beta ?
The intention has always been to keep it 1 based in JavaScript; I’ll check it.
I found the issue with the midiScript port settings in the (init) commands, and, as I suspected, it was a timing issue. The (init) commands worked as expected when started manually, but failed when started at plugin startup.
I have reordered things and added synchronization at plugin startup, which seems to solve the problem.
@thx538 , I am unable to reproduce your problem, but it is possible that it was caused by the same timing issue. Please try this version and see if your issue is resolved.
Breaking change: The channel reported in midi events is now 1-based.
Version 4.2.0.203:
Confirmed that the (init) commands are working as expected in bg scripts.
Actions for chaging ports are working as expected in all scenarios.
Setting Midi ports to #none# is working as expected in all scenarios.
Yes, it seems. I don’t see the “Plugin is loading …” window at startup anymore.
