This unit is a 100% original design ! Like firsts digital soundeffect units used by UK soundsystems in the early years, it uses separate push buttons to trigger the various modulations and thus allows the production of many different sounds !
However, this is definitly not a sampler ! This machine is a real digital siren : The sound-generation parameters can be set independently (Modulation Speed, Pitch, Sound Shape, and this for each sound). Thus allows the user to play on every of these parameters while staying easy-to-use (1 push button for 1 sound).
