It's both a single waveform and WT designer toolbox, tested and approved !

It generates compatible Solaris wav format out of the box for just one Ko per wave !
It's recommended though to transform them in raw format , follow this tutorial : https://www.hellomico.com/getting-start ... io-to-raw/
Copy / paste or drag the files into Audacity then skip to the end " Now we’re ready to export. Select option File->Export Multiple "
Example of samplepool.text file with one sample
[Pool]
name = E352
[Sample]
sampleindex = 1
filename = 01.raw
samplerate = 44100
samplelength = 256
loopstart = 0
loopend = 255
rootkey = 60
finetune = 0
lowkey = 0
highkey = 127
It works !
