"The Synti 1055 was designed as an improvement to the Satellite, which Thomas Organ Company aquired the rights to manufacture in 1973 this was produced about '75. However it is not quite a Minimoog, Moogs are upgrade to the Satellite. The Synti 1055, like the Satellite, is an analog preset monosynth with a 3 1/2 octave, 44-note (F-C) keyboard (7 more notes than the Satellite). The major difference between the Synti 1055 and the Moog keyboards is that the 10 preset tabs are above the keyboard instead of below. To the left of the keyboard there are 7 sliders for modifying a preset, including filter modulation, cutoff frequency, and resonance. The lid hinges to expose the inners and you can see by the piscs how clean that is."
