Introduction to Sooperlooper


Sooperlooper is a live looping sampler. It’s a great program! The main idea is to record and loop different audio samples in parallel. Already saved audio files can be loaded and looped as well. Many different features for recording or synchronizing make it a toy for long hours of playing around with. It interfaces with the jack audio connection kit, comes with ubuntu linux and, obviously, is free to download, copy and alter (GPL V2.0). Compiling the source is not as easy on ubuntu platforms (due to some package problems), I might post on that later.

Running slgui (the user interface comes separated from the actual looping server) a window opens with one (empty) stereo loop device and the jack master output (which is the input plus all active loops) is opened.

The main functions to start with are the record button, trigger, overdub and mute.  When recording is started the input is piped to that loop and recorded. Pressing record again the loop is played back (and looped) from the beginning.  Overdub starts recording over what is played back, mixing both together with a ratio defined by the “feedback” bar. When muted “trig” starts looping the sample, whereas “once” stops playback (of that loop) after the first round.These few functions give already a lot of fun. Using “undo” and “redo” to the left one can play happily with the first loop.

All this is nicely done when using a MIDI keyboard. In the preferences  one can make sooperlooper to “learn” MIDI events for different commands. With vkeybd (post) I arranged the main functions on the keys from 1-5 for the first loop and the rows below for others.  A detailed description of all functions is found on the website.

More loops can be opened and synchronized, more on that in a later post.
