Sound

OSCILLATORS The sound generator is based on a master oscillator with a MK50240 top octave divider chip, so it divides the generated oscillator square wave into the 12 semitone notes of an equal tempered octave. The left range split can have monophonic bass sound with extra volume and percussion attack control.

SOUNDS there are basically 3 sounds t"CELLO", "VIOLA" and "VIOLIN" you can mix a combination of three string sounds.
The String Melody II features also five different ensemble effect variations with pretty strange name: "O, ACC., SOLO, ORCH., and ORGAN"
O: chorus & mixer

acc.: accordion as plain out (w/o chorus) & mixer

solo: fast LFO - tremolo (FM), low LFO - vibrato (AM) w/ chorus & mixer

orch.: full orchestra w/o mixer and bass

organ: only low LFO chorus & mixer

ENVELOPE it is possible to control the attack and the decay times per keyboard zone.

EFFECT chorus generated by ITT TCA350 transistor bucket brigade along with a double low frequency oscillator
