GEM/LEM PK 4900 String Machine 1979 | HD DEMO

(c) 2018 by AnalogAudio1

Demo of the GEM/LEM (Galanti Group) PK 4900. Played along with Korg SDD-3000 for delay effects (right channel only).

The rare GEM/LEM PK 4900 is a multikeyboard containing a polyphonic section (called POLYTRON) including a string-ensemble (INSTA-STRINGS) and a monophonic preset synthesizer (called MONOTRON). Both sections are independently tunable, although intervals are not possible. Both sections have their own output on the backside. CHORUS and VIBRATO switchable.

It sounds somewhat cheesy, sometimes like a cheap organ (squarewave sound), but it was a cost effective keyboard back then. Actually some combinations sound very nice, especially slightly detuned. Although the strings are called "Insta-Strings", the strings are completely different from the strings of the LEM Insta-Strings keyboard I demoed two years ago.
