What's interesting with the newer generation of electronic gadgetry and probably the future of Instruments is,the way in which we interact with them,if you look at some of the instruments which change your way of interacting and making or thinking of music,like Touchscreens and such,its gives you a new way of expressing music or connecting with the technology,things like the Korg Kaoss pads or Kaossilators are just the surface of what is being scratched in this respect,more and more you see the music being less about composition but more about interaction,everything is samey in terms of sounds but Instrument designers have to cook up new ideas of what makes it more unique to interact with,its probably why so many people have gone back to the physicality of the tactile approach to shaping sound on legendary Analog synths,because the Japanese blackbox synths that came along to replace them,changed the way in which we though about synthesizers,we were brainwashed into thinking about sound in a different way and what we considered expression of ourselves,but we are analog programmed animals and we need some physical emotion in expressing ourselves,like a middleman between our ideas and the instruments we use.
If you look at things like the kindle,literature is still literature whatever form its in,the gadget has just removed the need for many processes to make a book,and its also changes our perception on interacting with the physicality of books,and the ability to carry many novels in one form,much like the MP3 player removed the need to carry Cds,eventually Books will become fashionable again when people have grown tired of the little physicality we require as humans to interact with our environment,I'm sure classic novels in hardback form will become priceless and definelty collectors items
I see the day when technology would remove the need for the actual playing of music and interpret your thoughts and ideas through some kind of telepathy software that bridges the gap between the mind and the instrument and translate your ides in your head to Musical ideas,because all that changes over time is the way we interact with our chosen instrument,the sound will never be changed,because where else is there to go with sound form????there are so many choices with instruments these days that nothing is classic anymore!!!How many synths these days really stand out as a unique sound form!!!everythings mass produced,
the interface between the musician and the music is the limitation and the way things will change in the future the days of legendary sound machines are gone,because we have vast access to libraries of sounds,its like having a classic Sculpture,then a company comes along and makes reproduction,soon the original doesn't look so interesting except to a few people who appreciate it
the only thing instruments need to be revolutionary these days is to remove the frustrations of the user because we all have imagination,sound seems to be less important to many people these days because everything sounds the same that the end result is the same regarless of what you use,its only the audiophile person who cares,especially with the throwaway society in music biz these days
Having an interface that gives you the freedom of expression of your soul and remove the limitations and frustrations of many people who feel overwhelmed by the way in which manufacturers force you to work in a given way,physicality is the way forward with sound these days
