MIKADO Analog Sequencing System

Prototype analog sequencer project on the Techno Toys site. Title link takes you to more info including a sample, details for each module and an image of the hardware in the flesh.

"Mikado is a configurable analog sequencing system, optimized for controlling a small (2-4 voice) analog modular synthesizer.

Mikado was designed to meet the need for a flexible, non-traditional hardware sequencer. A primary design goal was to include several modules for creating and manipulating rhythms using dividers, logic, and manual input. Flexible voltage sequencing, quantizing, signal routing, and manual inputs were other necessities.

Mikado is a "semi-modular" sequencer ala the Fenix or Serge systems, rather than discrete modules as other systems are. This is in keeping with the goal of controlling a small system, and reflects the designer's needs. Mikado could also serve as the heart of a larger sequencer system by adding modules from other manufacturers. In the present design, banana jacks are used for patching, though other types of jacks could be used by changing the front panel drilling accordingly.

Mikado's module complement and front panel were designed and specified by Jim Johnson. Electronic design and PC board layout are by Jim Patchell. PC boards for this project will be made available, and a customizable front panel is also available. It should be noted that, while the remaining material on this page describes the sequencer's specified configuration, the circuit and PC boards will have some additional capabilities, such as extra LED drivers, some additional sequencer modes, etc.
