Stopping a Midi Loop

[Lenvdb64]

Hi all
I am creating a drum pattern in the pattern builder in a step editor.
The notes have been added to a Midifile and I am running this file to test if it is playing back correctly
I have a "Stop" button which I want to click in order to stop the playback, but it seems that while the loop is running I am unable to click this button or any other button on my control form.
The code below for the Playback is on the Click event of the Play button

How did you work around this?

Hi,

First of all, read this article for future issues – Support. From the article you'll learn that code should be given as text, not as a screenshot. It forces me to type your code to show errors instead of just copying/pasting.

Secondly, you definitely need to learn how things you use works. SpinWait blocks your main thread which is the UI thread in your case. Why do you need to use SpinWait? I suppose you take it from the example from the Playback – Overview. But it's not a good idea to just copy/paste code without understanding it :-)

So there is no error in the library. There is no issue in using the Loop property. But there is an error in your code. You need to define OutputDevice and Playback as class fields (I hope you know C# or VB.NET) and use them across apllication without any SpinWait. Don't forget to dispose the device and playback instances.
