-Hello Fred, thanks for the reply. I thought it was different this time. regards. Hans
-Hello Frank, I use a memory of 16GB, installed on my keyboard and so far I have used 1.5 GB of all memory capacity, this means that I am not even using 10% of the memory capacity, and it works perfectly, so the possibility a) "full memory" is ruled out.
On the other hand there is a program called ADOBE AUDITION, which has the option of transposing audio files (WAV / MP3) to + 1 + 2 + 3 and -1-2-3 without degradation problems. I just installed it on my computer and it works great for what I need. anyway thanks for your time. regards. Hans
