Luppp Looping Tool: Scratching the Surface: Screen Caps

Luppp is a musical looping program for Linux, created by Harry Van Haaren of OpenAV.  Unlike the other looping and performance tools for Linux I have tried, it works for me.  The closest other thing I have had work is the DJ app, Mixxx, which I love, but it is really a different kind of animal.

Harry is hard at work adding functionality to Luppp, but here is a quick overview of the basics of Luppp 1.0.  Luppp is a very important addition to the Linux music community.  Thank you Harry!

The most basic thing to understand is that Luppp keeps time and everything happens at the beginning of a bar.  You click anything during a bar, it happens on the One of the next bar.  It's the simplest kind of quantization possible; it is what makes this kind of software work and having it in an app like this is something a lot of Linux users have been waiting for.

To load a sound into Luppp right click on one of the slots offered in each track.  I chose the top one in Track 1. Then you are asked how many beats long the sound is.  This is easily changed later.  Like Hydrogen, the assumption is that you are working only in 4/4.

Right click on a sound in a slot to change its length.  This multiplies or divides the tempo at which it plays.  Unlike software where you can only halve or double the tempo of a playing sound Luppp lets you squeeze any sound into one beat or stretch it all the way to 64, no matter what tempo it is playing at currently.
Luppp works correctly with JACK.  That's important.

Luppp has scenes.  Clicking the play button in the far right column starts every clip in that row.
You can also name your scenes.
Clicking another scene's play button starts clips in that scene and stops all other clips.
Clicking the play button for an empty scene stops all clips.
