Title link takes you to Fran Samshuijzen's Autophonic Instruments site with a number of modifications. The list includes the EMS Synth A, Twin Casio SK-1, a Sampler with the T.I. TMS 3477 IC, and this beauty, the Randrum."Originally a small analogue drumcomputer, consisting of a box with the three knobs, seen in the middle section with the dark inside.
One switch for six different patterns of 16 steps, with 3 sounds : basedrum, snare and hihat. Two potentiometerss for speed and volume."
