From e8382521c1a35ad59efea5e8cebb915a67c0008e Mon Sep 17 00:00:00 2001 From: Florian Jung Date: Wed, 5 Jan 2011 18:25:04 +0100 Subject: Finished note-compiler, seems to work. TODO: CLI The note-compiler now also generates code for set_param, and a function has been added which returns a pointer to a newly created object (important for loading from a shared object). There's also a destroyer function. TODO: - write a CLI for the note-compiler - let the note-compiler issue the build-commands on his own - make the synth load instruments from shared objects --- TODO | 1 + note_compiler/main.cpp | 107 ++++++++++++++++++++++++-- note_compiler/note.cpp.todo | 72 ----------------- note_compiler/templates/set_param.1 | 25 ++++++ note_compiler/templates/set_param.2 | 34 ++++++++ note_compiler/templates/set_param.nofilter | 13 ++++ note_compiler/templates/set_param.nofilterenv | 7 ++ 7 files changed, 179 insertions(+), 80 deletions(-) delete mode 100644 note_compiler/note.cpp.todo create mode 100644 note_compiler/templates/set_param.1 create mode 100644 note_compiler/templates/set_param.2 create mode 100644 note_compiler/templates/set_param.nofilter create mode 100644 note_compiler/templates/set_param.nofilterenv diff --git a/TODO b/TODO index e9ee05b..883a589 100644 --- a/TODO +++ b/TODO @@ -9,6 +9,7 @@ TODO für den synth ist, sondern zur not einfach *1 rechnen? o in get_sample(), beim aufaddieren zum out (und vmtl auf fm-)wert: erst nach dem addieren scalen, statt für jeden faktor einzeln + o wenn sync global aus ist, kann auch osc.sync genullt werden o filter_envelope könnte mit anderem ctor geinitet werden (weniger schreibarbeit) o notes compilieren und als .so-datei laden diff --git a/note_compiler/main.cpp b/note_compiler/main.cpp index 7f48c0b..8612bd2 100644 --- a/note_compiler/main.cpp +++ b/note_compiler/main.cpp @@ -657,12 +657,96 @@ void write_get_sample() out << "}\n";
