TOPIC: sounds distorted or speeded up...

hi, I'm Daniel and I'm making, as my first soundfont with some accordion samples. The problem is that it sounds distorted or speeded up ... This is if I use the preview on POLYPHONE with the virtual keyboard. But the samples listened to individually feel good ... is there a setting that I overlooked? If I use it on the DAW Studio Evolution Mobile it has the same problem ... While strangely on Caustic for Android the sound appears correct, accordion ... what could it be? here the 33 mb file

Root key and key range are not set for each sample in instrument part. They all play together.
Set it as in the picture below

thanks ... so a naive mistake of a novice ... but this job can not be done automatically? after all the program detects the notes of each sample ...

Yes, it can be done.
You select all samples from the Sample section and press the left-facing arrow button in the picture below.



and then you select the instrument from the instrument section and click the "sample auto-positioning" option from the "toolbox" button.
but you may run into problems if the frequencies of the samples cannot be estimated exactly.

really thank you ... you saved me a lot of extra work ... it works great!
