I downloaded the full 16 velocity layer sample for the grand piano for my raspberry pi 3 SamplerBox, how do I edit it to use all 16?
normally you can handle this by editing the definition.txt file. You need to put the definition for each layer. Have a look It is easy to understand. But in fact I have myself an issue with the number of layers that can be played, limited to 3 only, even if I put more, in sample sets and in definition.txt.
You could try also Erick's solution (see samplerbox2 http://www.nickyspride.nl/sb2/. ) But I am still trying to put multilayer fonction on my samplerbox...
