Vivid: yes i know this what you wrote, but i have huge library of 8-bit samples in iff/8svx format from my Amiga days, i think it can be supported loading of samples from Dropbox, iFiles or from native iPadOS file browser, i am not interested in importing samples from that modern synths on iPad. So i have to convert my samples into 16-bit stereo wav files, i will try it in batch processing in SoundForge, but after loading to Vivid tracker it will be again 8-bit mono? Weird.
Yes, if you load a 16-bit stereo wav sample it will converted to 8-bit mono since that is the sample format in Amiga mod-files. However, if you press the "STEREO" button on Screen 4B, any stereo sample will then be divided into two 8-bit mono samples.
I will consider adding support to iff/8svx samples. :-)
