The new version of PataTracker (1.3.0) now supports WAV files for samples.
Please have a try.
Congrats on the new release! I've tested it with WAV files of various sample rates and bits per sample and it plays them just fine. I really appreciate that you were so quick to incorporate the new feature.
Now, on a different note, whilst playing the Valoria DX demo song, I've noticed that there are sometimes slight audio pops or skips of a few milliseconds when the sequence changes... Is it just me? This never happens in other audio applications such as Reaper or Renoise, at least not until I have dozens of tracks, each with several VSTs. In any case, I have checked and it's not the CPU, as it never goes above 10% when playing the track. Hope this information is useful.
Edit: Disregard the information about the audio skips, I've figured out it was because the buffer size was set too low, so I changed it in the settings.
I guess it's time to write some good tunes now. :)
