East Coast/West Coast thing doesn't limit itself to hip hop. In synth world it is lot less violent and doesn't have as much harsh language. In synth world it is about philosophy of what synthesizer should be. East Coast is about creating instrument suiting regular western music. I am not talking about country. I am talking about all western music where octave is divided into 12 steps. West Coast was about revolutionizing the music by throwing all the rules away starting from regular scales. On east Bob Moog was figure head and on west it was Don Buchla. It might be needless to say East Coast became popular while West Coast stayed in obscurity.
You really have to like synths to know West Coast even exists. It has mostly lived on modular side. I don't remember seeing West Coast hardware that isn't able to connect any modular format or was in some modular format. That is part of the philosophy. Make Noise 0-Coast (in picture above) is one of those synths. It is not completely West Coast. It is something in between East Coast and West Coast. I would say it is West Coast synth made for people familiar with East Coast. It is easy gateway to West Coast synthesis.
0-Coast is one of those instruments bridging cap between East Coast and West Coast. It is coming from West Coast side. But East Coast side is also taking steps towards West Coast. Arturia's Brutes and Korg's Minilogue and Monologue take little steps towards complex oscillators of West Coast with their wave shaping capabilities. They do more than just extending pulse width modulation which has been standard in East Coast.
This is not only hardware thing. Native Instruments have West Coast Blocks in Reaktor 6. Softube added emulation of Buchla 259e into their Modular software couple months ago. Arturia just upgraded their V Collection to 6th version. It includes virtual version Buchla's Music Easel. This makes two virtual versions of Buchla hardware in short time. V Collection is collection of classic instruments in virtual form. Music Easel is first West Coast synth in it.
I hope this this gives more West Coast for us after West Coast becomes more familiar to musicians. I don't need things throwing away western musical scales. I like to have more instruments like 0-Coast which are reasonably priced and easy to use for people more familiar with East Coast. It is time for something new and fresh. Mix of East Coast and West Coast could be it.
