The design process can be split up into a few different sections. First the DSP side of the synth needs to be developed. This will include the sound and modulations sources as well as the FM component as those are the most important part of the synth. Next will come the analog component with its filters, amplifiers and any analog effects that I may choose to include. After this will come the polyphony and determining how best to route the DSP signal to the different voice cards and how to route multiple signals into the effects and output. After that comes interface design which includes both the placement and labeling of front panel controls and designing the software interface for the screen. After this comes rigorous testing to ensure that everything on the front panel controls all the voices properly and is easy to use as well as ensuring consistency between the voices and overall QA testing.
