1. About Analog Sequencers
Most people think of an analog sequencer as basically a device which can "play" a series of pre-determined notes on a synthesizer automatically. This is the most common usage to which a sequencer is put to.
But in fact, the SQ-10 Analog Sequencer is capable of much more than simply establishing sequences of pitch levels. It should be remembered that the monophonic synthesizer is a device which uses voltage control to vary the three elements of musical sound: pitch, tone color (timbre) and volume. The practical advantage of the SQ-10 is that it will simultaneously generate three different voltages at each step in a pre-established sequence. By utilising the SQ-10 with an "interfaceable" synthesizer (such as the Korg MS-10 or MS-20), the user can vary not only pitch levels, but the entire composite synthesized sound by presetting the instrument's pitch, tone color and volume at each step. This opens up a considerably larger number of practical applications, particularly for live performance situations.
In addition, the Korg SQ-10 Sequencer has the unique ability to vary its own "rhythm" by patching a sequence of voltages into its own internal voltage controlled clock. This feature enhances even further its performance capabilities.
2. Features of the Korg SQ-10 Analog Sequencer
•Capable of studio grade performance, with 12-step, 3-channel, 6-mode sequences. Maximum sequence is 24-steps.
•Built-in Voltage Controlled Clock Generator allows continuously variable step spacing control by means of frequency modulation.
•Each step has an independent Trigger Out jack. You can have a sequence of as many steps as you want. Or, use a number of synthesizers to create complex rhythms.
•Built-in Portamento function allows control of output voltage change rate for both Channel-A and Channel-B.
•Continuously variable relative duty system controls output periods within step time spacing for both Channel-C and Sequence Trigger.
•Built-in analog mixer makes possible additive mixing of output voltages from each channel and series connection of a number of sequencers.
