Please look at some You Tube videos on how to use Sampler. There are many, but, of course, the ones I see are in English, and I assume you would prefer to have them in French. The process is really fairly simple, but in the kit you are using, there are going to be samples placed at every available midi location except 32, 33 (G#0, and A0). Drums at 36 through 38, 40 through 43, and 45 through 51 have multiple samples.
You open the Sampler instrument and drag each sample into its proper location in Sampler. Starting with the first sample in the kit, Liverpool Bass C1_1.wav. When you drag that into sampler, ti will give your several options. Select Chromatic. Sampler will the sampler a C1, but you don’t want it there. Turn off the “Pitch” button, and drag the sample to C-2 in the Sampler keyboard,. C#1 wav will go to C#-2, etc.
i realize this is confusing, and you probably need to see what is happening. That is why I suggest you find a YouTube video.
If I get time later this week, I may decide to build this kit as a Sampler instrument, and document my process. If I do that, I’ll give you a link to the kit and the documentation, so that it will be available for future kit building.
But today, I am trying to finish vocal tracks on a song I’ve been recording for the past couple weeks.
