Architecture of the Ultra Analog
The Ultra Analog is a very adaptable and versatile two-oscillator synthesizer. The different control
elements of the synthesizer have been grouped into three sections in the graphical user interface
shown in Figure 1.

Figure 1: Graphical user interface of the Ultra Analog Synthesizer.
The main section of the interface, the synthesis section, is related to the main sound generat-
ing and processing modules including two oscillators, a noise source, two multi-mode filters, two
LFOs, four envelope generators and two amplifiers. These modules have been laid out into two
symmetrical rows on the interface following the general internal signal flow of the synthesizer as
will be described below. The column to the left of the main section is the control section which
includes the modules related to performance and the processing of MIDI events. Finally, the top
row of the interface is an output effect stage which includes a multi-effect module, master clock
module as well as a master level and a recorder module.

The individual modules and controls of the user interface will be described in detail in Chap-
ter 4. We will now take a closer look “under the hood” at how the different modules are connected
