Tapir Lisp is a Lisp-like language for describing a directed graph (it's not a tree); it define a sound signal flow. Note that Tapir Lisp does not have conditional expressions, functions and thus local bindings. It has some features below:
- create unit generator instances
- define sound environment (e.g. bpm)
- define global variables
- for creating multiple signal output
S-expression reader and printer are placed at ../sexp.rs.
Unit generators generate sound signal. The output signals may be depend on values from other unit generator's or not.
For details, see make_unit() in ./eval.rs.
There are some types of special forms.
def and environment modifications are that.
def evaluates the secound argument and set it to the name of first argument in global binding.
If set to same name twice Tapir Lisp will cause error.
Environment modifications are simply modifying bpm or measure via bpm or measure.
