Description	The ER33 is an 9 voice synthesizer with 8 oscillators and FM based sound sound structure very similar to the Yamaha DX 7. All 8 oscillators can be edited simultaneously or adjusted separately. The first 12 parameters are presented this way on the non backlit LCD screen. It should be noted the LCD display is readable at any angle a feature this instrument is known for. A second set of editing parameters deal with the overall sound of the instrument. Some of the parameters that are familiar to synth enthusiasts are Pitch Envelope and LFO Vibrato. A chorus effect rounds out the sound shaping section. A nice feature in the editing portion is an over all level control for matching volume levels between programs. An additional set of editing features deal with the whole setup of the ER-33.
