Importing Long Wave Files

One example:

But also pattern effect commands like retrig would rather be used from a different perspective (on current position) than how retrig is currently applied (at the beginning), so this makes this effect and a few the other effects pretty useless for this samples type.
I think this really belongs to the audio-tracks brainstorming discussion rather than here.
