New inflatable 88-note Keyboard - fits into a laptop-sized case.
With the amount of electronics now capable of being fitted into, for instance, a laptop, and the mallability of connectors, this new keyboard will be welcomed by all keyboard players who currently struggle up and down stairs, along
100' hallways etc. to fulfil bookings. Complete with it's own compressor (which also fits into a laptop-sized case), it combines all the features of everyday keyboards without the bulk.
Other musical instruments may follow suit - such as drums (not symbals of course!!)
Obviously the plastics used would have to be able to withstand high pressures if the instruments are to feel solid.
As an addition, for one-man-bands, other inflatable members can be added so that a virtual 5-piece or orchestra could be supplied depending on the booking.
