Hello! I wrote a new version of the script. It is here: http://www.linuxmusicians.com/viewtopic.php?f=4&t=9875&p=30… I covered some little bugs, improved his speed and I also mixed samples using sox. For example, if I had four samples of the same note, I mix them in a new file, changing his name, format and metatags. Do you think it is still too similar to the one provided on the website to re-distribuite? It doesn't depends no more on ffmpeg, because in some distribution (Debian) it is not distribuited with support to mp3. I use lame instead. I relaunch my questions: 1)what options would you use to create this orchestra from London Philarmonia samples? 2)Do you want help me? 3)how can I obtain sustain effect compatibly to linuxsampler? 4)I'm new in linuxaudio.org. Do you think it is the case to open a new thread in the developement section? Federico
