synesthesia 

A condition in which one type of stimulation evokes the sensation of another, as when the hearing of a sound produces the visualization of a color.

NOT an illness like schizophrenia, just a neurological condition.

I am a synesthete, and I taste words.

Synthaniac 

Someone that plays synthesizers when he/she isn’t listening to them, taking about them, thinking about them, blogging about them, reading about them or planning his/her next synthesizer related purchase.
Likes to patch at ridiculous hours of the morning and turns the amp up as loud as humanly possible so that everyone else within the radius of Chernobyl can enjoy it as well. They own a specific pot dedicated to different types of audio cables and more often than not keep they’re favourite synth somewhere close by for emergencies.

After a successful night out Dylan decided he was feeling creative and it was time to craft a new wave/synthpop patch on the Korg MS2000. His neighbours however, were not synthaniacs and so, did not agree.

"Some F*ckface just beat me for that Juno on ebay, now I gotta spend all day looking for a new one."

synesthesia 

A condition where real information from one sense is joined with false perceptions from other senses. People with this condition can "see" sound, or "smell" colors, etc. The experience varies from person to person. One synesthetic may have a solid color overlaying their vision, corresponding to pitch and volume; another may see different colors for different letters (K is always red, C is always blue for example). Synesthesia is often experienced when taking high doses of LSD; the likelihood of this effect appears to directly correlate to dosage.

Synesthetics often become composers or musicians; their unique ability to visualize sound is a distinct advantage.

Synthesian 

A person who learns piano songs from synthesia tutorials. These people usually can't read notes because they're too lazy to learn them.

Musician? More like Synthesian, haha!

Synesthesia 

A condition which causes the senses to be crossed wired. For example: numbers, letters, words, music can all have colors, shapes, personalities, feelings. The equivalent of being born on LSD. Introverts are more likely to have it than extroverts.

Because of synesthesia; the number 4694 looks like beautiful fall colors to me.
