I believe that this was made many years ago, and maybe even from a standard kit, that you could buy in an electronic store.
With a sampler it was possible to make your own recordings/sounds and use the in your work. For the actual sampling and processing of the sounddata, there was a wide range of software. I used the Aegis AudioMaster II and later III, to process my samples on the Amiga, before importing the samples into ‘Editor’.
I believe that the Aegis AudioMaster 3 (or AudioMaster III) software also came with a hardware sampler.
