My family had a Lowrey console organ since I was 10 or so. My first keyboard was a synthesizer Radio Shack made in the 70s. I can't remember the model, but I mowed grass and saved all summer for it. It cost $400 and was mono. It played some "loops" but mainly was modeled after a moog having a lot of knobs and sliders to change the sounds. I used to hook it up to a oscilloscope to study the waveforms. It was cool at the time.......................I wouldn't mind having it now either!
