why is MIDI scripter dropping events after 20x loops in MainStage 3

my drum riff script seems to work up until the riff is repeated (i think around) 20 times. then some notes like snare... start to dissappear. if i hit the global stop and play again it works. also if i reload the script it doesn't help which makes me think... but come up with the road to nowhere. any ideas?
The problem starts at beat position 640 (20x 32 beats per loop).

The scripter plugin was loaded on a drum kit software instrument channel and works great for the most part.
I've traced each beat with another scripter plugin and all the notes have been logged, so i assume they've all been sent properly. All the notes should be there but they just can't be heard.
I've tried all kinds of things, i'm stuck!

get() function returns an empty pixels array in p5.js

The thing that i wanna do is similiar with this video. In p5.js, I am using get() function. After use this, I will create small images (by dividing big tileset) and push them into an array. But in my code get() returns an empty pixels array. Here is a part of my code:
tilesImages = []; // tiles array
function preload() {
let tilesImage = loadImage(TILEMAP_PATH + "tiles.png", () => {
console.log("Tiles loaded successfully"); // It logs this
}, () => {
console.log("An error occured when tiles loaded");
});
for (let i = 0; i < TILE_HORIZONTAL; i++) {
for (let j = 0; j < TILE_VERTICAL; j++) {
let x = i * TILE_SIZE + TILES_SPACE;
let y = j * TILE_SIZE + TILES_SPACE;
if (i == 0) {
x = 0;
}
if (j == 0) {
y = 0;
}
var img = tilesImage.get(x, y, TILE_SIZE, TILE_SIZE); // get tiles from tileset
tilesImages.push(img);
}
}
}
function setup() {
console.log(tilesImages[0].pixels); // returns empty
}
I tried to use this but it just draws vertical pink lines to my small image.
My tileset: https://www.kenney.nl/assets/pixel-shmup (on right)
I am using single images now but I want to know the solution of this problem. Thanks

I believe the issue here is that you are not waiting for the image to actually be loaded. The loadImage function is asynchronous. That is, it only starts the process of loading the image, but it returns before it actually finish loading the image. So any code that comes after that will run immediately, while the loading is still in progress. You can use the callback function to run code after loading is complete. Here's a modified version of your code that should alleviate the problem:
tilesImages = []; // tiles array
function preload() {
let tilesImage = loadImage(
TILEMAP_PATH + "tiles.png",
() => {
console.log("Tiles loaded successfully"); // It logs this
// Wait until loading is complete to use tilesImage.get()
for (let i = 0; i < TILE_HORIZONTAL; i++) {
for (let j = 0; j < TILE_VERTICAL; j++) {
let x = i * TILE_SIZE + TILES_SPACE;
let y = j * TILE_SIZE + TILES_SPACE;
if (i == 0) {
x = 0;
}
if (j == 0) {
y = 0;
}
var img = tilesImage.get(x, y, TILE_SIZE, TILE_SIZE); // get tiles from tileset
tilesImages.push(img);
}
}
},
() => {
console.log("An error occured when tiles loaded");
}
);
}

How to get current segment .ts information of m3u8 standard playlist?

We are using videojs.fairplay.js for playing DRM content in MAC safari browser. At first while playing DRM video we get one standard playlist (.m3u8) that has defined stack of segments (.ts). We need to know the each segment information and there complete meta information like (length, type, url, etc..).

var video = videojs("my-video");
video.on('playing', function () {
console.log("The video has been playing");
var segment = get_current_segment_info(this);
console.log(segment.uri);
});
function get_current_segment_info(obj, old_segment = null) {
var target_media = obj.tech().hls.playlists.media();
var snapshot_time = obj.currentTime();
var segment;
var segment_time;
// Itinerate trough available segments and get first within which snapshot_time is
for (var i = 0, l = target_media.segments.length; i < l; i++) {
// Note: segment.end may be undefined or is not properly set
if (snapshot_time < target_media.segments[i].end) {
segment = target_media.segments[i];
break;
}
}
// Null segment_time in case it's lower then 0.
if (segment) {
segment_time = Math.max(0, snapshot_time - (segment.end - segment.duration));
// Because early segments don't have end property
} else {
segment = target_media.segments[0];
segment_time = 0;
}
console.log(snapshot_time);
console.log(segment.uri);
console.log(segment.resolvedUri);
console.log(segment);
return segment;
}

For Loop refusing to Loop; Works Perfectly Fine if Run Manually

Alright, so, hopefully this is a simple enough question. I'm sure that it has to be something simple and stupid that I am not doing right. I'm building an app to program my exercise routine into so I can keep track of it every week (and to learn app development using Cordova). Within the code, each time I come back to the exersetup screen I want to read the saved exercise file, parse it back to an array of objects, convert those objects back into exercise objects, then display them on the screen. I have a loop that is supposed to check each element of the array to process the information, then display, then repeat until it has done this for each element in the array. It works perfectly fine for the first item, then stops. If I manually run the loop multiple times, it functions perfectly. Not listed is the code for the function addRow(), which simply adds a row of formatted dropdown selectors for input, then increments rowNum to keep track of which row it is operating on. Any help you guys can offer is appreciated. If I need to submit more information I would be happy to do so. Here's the loop in question:
EDIT: Fixed some things to the suggestions in the comments below. Code still functions the same. Works perfectly fine on first run through loop, then stops. If I continue to run the loop manually (declaring it over and over again in console) it works fine, but it will not, for some reason, run the "for" loop. I've also included the rest of the function that the for loop is nested in, in case that helps.

A function to preload images - need to draw them now, but how?

I'm dabbling with canvas. And I'm a little lost on something.
I have this function:
function preloadimages(arr) {
var newimages = []
var arr = (typeof arr != "object") ? [arr] : arr
for (var i = 0; i < arr.length; i++) {
newimages[i] = new Image()
newimages[i].src = arr[i]
}
}
And I call it like so:
preloadimages(['images/background.png', 'images/hero.png', 'images/monster.png']);
The only problem is, I don't know how to then draw them again later.
If I was preloading one image inside my js I would say:
var bgOk = false;
var bg = new Image();
bg.onload = function () {
bgOk = true;
};
bg.src = "images/background.png";
and then further down when I wanted it drawn I would say:
if (bgOk) {
context.drawImage(bg, 0, 0);
}
And that would be that. The problem is I have made a preloader class, I don't really know how now to call in just the image I want to draw now, or even how to implement the bgOk idea so that if it loaded ok, I can draw it, and if not, leave it alone.
Could someone advise me on this? I'm basically just trying to go more class based rather than the dirty great mess I normally have with a huge javascript file that is ugly and not as maintainable.

This seems to be a complicated problem, but in reality isn't as bad as it looks. If you want to use pre-existing code, or just want to look at something for ideas you can have a look at: http://thinkpixellab.com/pxloader/ This library was used in the HTML5 version of Cut The Rope.
A simple custom implementation could be something like the following:
function loadImages(arr, callback) {
this.images = {};
var loadedImageCount = 0;
// Make sure arr is actually an array and any other error checking
for (var i = 0; i < arr.length; i++){
var img = new Image();
img.onload = imageLoaded;
img.src = arr[i];
this.images[arr[i] = img;
}
function imageLoaded(e) {
loadedImageCount++;
if (loadedImageCount >= arr.length) {
callback();
}
}
}
And then you can call it like this:
var loader = loadImages(['path/to/img1', 'path/to/img2', 'path/to/img3'], function() {
ctx.drawImage(loader.images['path/to/img1']); // This would draw image 1 after all the images have been loaded
// Draw all of the loaded images
for (var i = 0; i < loader.images.length; i++) {
ctx.drawImage(loader.images[i]);
}
});
If you want more details on asset loading you can have a look at the asset loading section of Udacity's HTML5 Game Development course https://www.udacity.com/course/cs255

A function I use:
function ImageLoader(sources, callback)
{
var images = {};
var loadedImages = 0;
var numImages = 0;
// get num of sources
for (var src in sources) {
numImages++;
}
for (var src in sources) {
images[src] = new Image();
images[src].onload = function() {
if (++loadedImages >= numImages) {
callback(images);
}
};
images[src].src = sources[src];
}
}
You call it like so:
var sources = {
bg: path/to/img.png,
title: path/to/img/png
};
var _images = {};
isReady = ImageLoader(sources, function(images) {
_images = images;
});
And then to access your images
_images.bg;
Example: drawImage(_images.bg, 0, 0);
