So, I finally cut a sample pack today (it’s up at op1.fun). I used my Zoom to record audio from a couple of pocket operators, whacked up the WAV file in Wavlab into half-second clips, and used the OP-1 Drum Utility to make my AIFF file. It all sounds fine, and installed with no problems. However, when I pick that sample pack in the Drum sample menu, as soon as I strike a sample the OP-1 starts a noticeable hiss that continues even when nothing is playing, and persists after I switch back to the synth, and only goes away when I turn it off and turn it on again. The hiss is not in the original samples, and even if it were, the creepy thing is that it plays whether or not a sample is playing, and once it starts, persists even when another instrument is selected!
Has anyone else seen that? I need to try installing one of the other patches from op1.fun and see if that does it too, or if there’s something whacked about the AIFF I made using the drum utility.
