 There was a 'touch' (delayed) vibrato setting, and a 'glide' switch on the foot volume pedal (found also on many Lowery home organs), which dropped the pitch one-half step.This made it unique compared to other string machines that had only one oscillator and relied on delay line chips to produce the ensemble effect (chips that have to reduce the audio bandwidth to mask the digital clocking).It was a heavy machine - about 70 lbs - and was rather durable except for the removable keyboard cover which looked like it hinged up, but rather pulled straight out.
