Story

The Mark II is an enhancement of the SX-150, also known as the Synthesizer Chronicles special kit. The original “Chronicle” was a kit that you had to assemble, and included variable controls for LFO Rate, Attack, Decay, Pitch Envelope and Cutoff. The three switches are for Resonance ON/OFF, LFO Wave (square or triangle) and Power (Off, Low Volume and High Volume). The External Source jack allowed you to drive the kit from a voltage source instead of the resistive strip. The build-in speaker was very tinny and thin, so using the Output jack to drive mono headphones or run audio to a mixer was a much better choice.

The Mark II builds on the original, replacing the Resonance switch with a variable control, and adding an LFO Depth control. The power switch has been changed to Off, On and Gate; where Gate disables the Attack and Decay controls. The External Source jack has been relabeled as “Line In”, but probably works the same way. Finally there are two new pressure-sensitive push button switches: VCF Modulation and LFO Modulation. The tiny built-in speaker is still mostly pointless – you’re better off plugging headphones into the Output jack instead. The Output audio is pretty rich and clear in comparison. Now, this is not a kit; basically you just get a small box that contains the Mark II, a sheet of silvery labels for customizing the knobs, and a foldout sheet with warnings (don’t play the Mark II in the shower, and don’t leave it in your car with the windows rolled up in the summer) and brief descriptions of what each of the controls do.
