Pour y parvenir, je compte mettre Ableton Live 5 en Rewire (= câble virtuel entre plusieurs logiciels, qui leur permet de se synchroniser et de jouer ensemble) slave de Reaktor 5 pour qu'il récupère sa midi clock automagiquement (Reaktor peut analyser un signal externe et caler son horloge midi dessus). En effet, cette solution a été fournie dans ce topic, dont voici le contenu :
" I made a thing for doing this (listen to an incoming audio source, and then generate a midi clock as to its tempo, all in realtime. The idea is to use it in order to get Ableton Live to auto beatmatch to an external audio source) in Reaktor Core. It uses windowed peak detection. 1ms window seems to work well for most applications. 1st High-pass the signal at 1/window size (secs) Hz (FIR is best if you can afford the CPU time). Then you need to make a peak detector that detects the peak in each window. Then a small rolling buffer (8 bytes works well) which remembers the last 8 peak values. Average these all, then compare the most recent peak to the average. You can then set a ratio threshold to detect peaks. between 20 to 50 works for pretty reliable beat detection. You can also fuck around with this. That is an option... I stopped changing it when it did the job well enough for me. "
Merci d'avance,
