Hi Mattia,

Possibly the reason you dont like/use live\_loop is because you feel it cannot be controlled ?

With a very simple framework and a couple of defines, you can start and stop the audio output of  
any live loop, allowing you to use it anywhere within a composition.

I posted a simple framework and example a long time ago… I’ll try find the post for you.

Eli…

EDIT: I cant find the post I want but see my comments in these 2 posts, they pretty  
much explain how to use a tracking variable to turn the sound output of a live\_loop  
on and off as you require

> Hello World! Some simple house beats. I like using a ‘sequencer’ function to control the timing, then pass it a series of Procs which define the tracks, one for each instrument - gives you an easy way to control the timing and also the expression of each beat. Also makes mixing in new instruments a breeze. Note that the kick and snare here are samples, but the hi-hat is a noise synth; wrapping them in functions with the same interface (my\_samp, my\_hat) means you can treat them the same way whe…
