I've been working on a boomerang looper at the request of an artist for some content. Basically a live stream comes in, and when you press the space bar it creates a loop. When you press the space bar again the live stream commences.

I thought I had matrixset indexing frames correctly but I am noticing a glitch. After creating a loop and commencing the live stream there is a momentary pause that is very frustrating, sometimes its barely noticeable. In other words, when transitioning from the loop back to the live stream.

I am wondering if anyone has advice on my patch on how to make this glitch-proof or an alternative. Thanks in advance for any advice offered!

Hi Mike I tested your patch and I have no pause

if you are using full hd content consider to use opengl

and check your codec of your live stream or movie file

Hey Micron, thanks for testing out the patch. Its nice that you don't notice a glitch. Sometimes I don't see a pause either, so its nice to have another pair of eyes verify this.

I am continuing to play with the variables. I think I'll try the HAP codec, and possibly an openGL version of this, although Im not sure what the openGL equivalent to matrixset is.

Hi Mike, I also tested your patch and didn't notice any pause or glitch. If you want an openGL version of matrixset I would recommend you check this article by Rob.

Thanks for digging that article up. Will definitely have a look. 

since that article was written there is a new object that makes this process easier, as JS object called jit.gl.textureset. it is a direct replacement of jit.matrixset, but stores textures instead. 

search the file browser for jit.gl.textureset-example.maxpat for an demo.

also had this disorder with your patch, but i replaced the matrixset with the textureset, and now it works great.

Thanks Rob, for the textureset suggestions, and Herr Markant for the revision!
