Hi,

Sorry I should have read the documentation properly. When do you plan to bring the plugin operation to 1024 frames? To connect it and make it work I could not do it via ardour routing but directly by routing qpwgraph, one of the most used gui for pipewire. Do you find that? How do you usually do it? Last thing: my electric guitar has a somewhat defective pickup and when I make chords these are not read very well.

Thanks for this free plugin for linux! Is Awesome!

I typically usw and test it in carla and Jack. 1024 frames is too high. The goal is to Make the plugin close to realtime so rather go for 128 or 64 samples. The Plugin works besteht with the bridge pickup. You also need to play with the input gain in your sound interface.
