Continuous / discrete
Not all dimensions have to be continuous
For example, in many trad. instrument, pitch choice is discrete
(keyboard, guitar, wind…) (even if in the guitar and in wind
instruments, pitch can depend on other factors, and therefore the
output pitch can be more “continuous”, its initial choice is still
discrete)
In the piano, for ex., each event has a dimensionality of 2 (one
discrete – key, the other continuous – velocity), but several
simultaneous events are possible
As in the analog world, in the digital world, discrete selections can
be addressed in diff. ways (they can have 2 or more states, they
can toggle or not, they can exclude previous choices – radio
buttons …)
