synth | latest code to make your own virtual sound synthesizer | Audio Utils library

I am new to Tone.js and have a problem with the Gain object. I have a volume slider set up in html as follows:

I have a design I've implemented using vhdl that is triggered based on a clock that sends an input signal to one of 8 output channels based on the sel input and also another 2 bit input. The elaborated design shows a lot of nesting due to the many if-else statements. So, I'm curious as to if there's a way to alleviate the nesting using case statements or some other method. I'm unfamiliar with doing this using case statements because I have two inputs that determine the output channel. The code that I currently have is displayed below.

I am following this tutorial to deploy to ECS using CDK, but when I deploy I get this error after deployment

I'm trying to put together a relatively simple stack on AWS CDK that involves an ApplicationLoadBalancedFargateService from aws-ecs-patterns.

My problem involves secrets. I have a secret in Secrets Manager that has several key/values (I think technically it's stored as a JSON doc, but AWS provides a key/val interface), and I need to pass them to my containers individually. I do this currently in an equivalent non-cdk (made in the console) stack by simply specifying the key, like this: arn:aws:secretsmanager:us-west-2:[acct]:secret/name-??????:KEY::, where `KEY is the secret key, and the correct value is inserted into the container as an env var.

When I try to do that with CDK, I get an error when I cdk synth:

new to the CDK and relatively new to AWS

I'm following this tutorial which includes creating a fargate based private API, and accessing it on the public internet through an ec2 instance which is publicly exposed.

I'm picking through, minimally correcting various issues which gets everything running. It comes time to build with:

I need some help with the bootstrap accordion

I want to add the border-bottom-color: red for the header of an item "Collapsible Group Item" div when it's open
and remove it when the div is closed

I am trying to add the class through Jquery and that class will have the border-bottom-color: red CSS.
but it's not working, can someone tell me where I am wrong

Expected:
When the div is open the class will get add else it will get removed

Result of the code I have written:
The color is getting added to all the div at the same time irrespective of open div

I'm learning SwiftUI and tried to implement the MVVM architecture. The idea is simple, I tried to add photo to a list which it changes based on the weekday selected. The photos are locally saved.

However When I used the MVVM architecture, it complicated the whole situation. Specially if you want to save each schedule of the weekday separately. Because each weekday is a separate array. I'm sure there is a much easier way to do the code below. But I didn't figure it out.

Running my AWS CDK on Azure DevOps Pipeline, but getting this Cannot find module '@aws-cdk/cloud-assembly-schema' error. No idea what goes wrong at the moment.

Run cdk synth myStack

I am trying to setup a varnish cache where the varnish instance is hosted on one server and the backend is on a different server. They are both on aws lightsail instances. The issue I am having is when I try and go to the site, I get the Error 503 Backend fetch failed error. Here is the varnish default.vcl:
