this auction"# Controls on/near the hand-grip: Bender - up only, like a bending a guitar string, this stock control is proportionally assignable to pitch and/or filter frequency.
# Modulation switch - momentary, like the bender up-motion, this stock control applies modulation such as vibrato or other effects.

# Filter frequency - moved here for opening or muffling the overtones of the oscillators - this is pretty much the most expressive knob on the keyboard, now available for your left hand anytime during performance.
# Hold - a second hold button, in addition to the one on top, but here you can use it when standing.
# Portamento - this also works in parallel with the stock portamento switch, but is a momentary toggle, allowing you to slide between notes, then immediately return to non-slide mode when you relase the switch.

# Octave - moved here for very fast octave changes, reachable by your left pinky finger, leaving your other left hand fingers free for the other controls. This gives you a 4.5 octave range durinng stand-up performance, without your right hand ever leaving the keyboard - uheard of in most strap-on synths!
# Volume - moved here for easy fade-ins and fade-outs while playing.
# (Repositioning the controls does not alter the original sound of this warm and fat-sounding vintage gem. Previous mounting holes have been blocked, but the paint does not match all areas perfectly, due to the age of the plastic. The unit has been professionally serviced this year, including cleaning of all controls.)"
