You can join together multiple small sample loops (for instance 128 bytes) and replay them without gaps.
When used along with sample mip-mapping you can get quite nice audio quality, compared to just pitched samples replaying. Here is a production that uses this tech:

very cool, thanks for the video. This is a perfect example of "chip music".
Historically, this kind of wavetable synthesis was pioneered by the German company PPG, and implemented in their "PPG Wave" line of synthesizers from the end-70s to the mid-80s.
For instance, the PPG Wave 2 uses small 128 byte wavetables with 8-bit resolution, which contain tifferent types of harmonic overtones.
The smooth change in harmonic content is being achieved by linear interpolation between multiple wavetables.

Your example is aiming at C-64 like filtered sounds, but I think it would not be that hard to implement this sound engine on the Amiga.
