Outline

Here is an example of schema and generated table for MIDI Gateway module:

There are two ways to modify a component parameter. They are:

  • Direct control using a component address
  • Indirect control through a unit

Component Address

Every component has its unique address in order to exchange its parameter via data bus. A component address is a 4 byte integer like IP address. Thus, you have two ways of address management — static and dynamic.

Unit

*** TODO: rename unit to union

Analog 3 will have many parameters that may cause difficulty in control them. Unit helps simplifying synth manipulation.

A unit is a virtual component that consists of zero or more components or units. It has its own control parameter. A unit is a component on data bus. Thus it has a component address. Updating the unit parameter causes changes in its sub-components at once.

An example usage of units is building polyphonic perspective. When you build a four-voice polyphonic synthesizer, you make a unit for each synth parameter (such as VCF cutoff frequency) and recruits corresponding physical components of the four voices. Its representation looks following:

Another example is bundling multiple parameters to simplify manipulation.
