Assemble a grouping of digital oscillators within a computer program such as Pure Data or Super Collider. These software applications allow users to build their own synthesizers from the most basic levels, creating opportunities for complete customization and control. Unlike digital audio workstations such as Logic or ProTools, Pure Data and Super Collider do not use a designed interface. Instead, users must create schematic diagrams or coded transcriptions of the wave generators they wish to use.
Program the synthesizer preset on a keyboard such as the Alesis Micron or Korgo microKorg. Although these devices do not allow for the degree of customization found in the previously mentioned software packages, they provide users with a more intuitive interface in which they can customize attributes of the oscillators included in the keyboard.
Customize the simulated oscillators and filters in the modeled synthesizers of a program such as Logic and Reason in order to produce an authentic, synthesized tone. Although these programs do not authentically replicate the behaviors and characteristics of the original hardware voltage-controlled Moog Synthesizers, the rarity of these hardware devices and the abundance of software modeling packages make these DAWs a viable option for synthesizer creation.
Download the technical schematics for the synthesizer or synthesizer effect you are interested in designing (i.e. flanger, modulator, etc.) and assemble the device as it is described. For the layman, this may prove to be a difficult, if not impossible, task. Ensure that you have developed a working knowledge of electronics and manufacturing before beginning this process.
