Now, a pfactor-influenced output which is constant zero is considered as still constant, because pfactor*0 is always 0. 2011-01-09T12:06:58+00:00 Florian Jung flo@thinkpad.(none) 2011-01-09T12:06:58+00:00 urn:sha1:216f7933c5b4b65f7f45d3c459ead10f160d124b 2011-01-08T17:27:40+00:00 Florian Jung flo@thinkpad.(none) 2011-01-08T17:27:40+00:00 urn:sha1:d84da6cdfb9027a67b8ab50fe2c23374acc3b245 2011-01-08T16:58:48+00:00 Florian Jung flo@thinkpad.(none) 2011-01-08T16:58:48+00:00 urn:sha1:82e74a33661d235029f413eff2b21c4e29e057bc The following has been changed - Note::set_param now sets orig-values and does an apply_pfactor() - Note::reattack now also reattacks the filter's envelope - oscval[i]=0 has been removed as it's unneccessary in Note::get_sample() - in Note::get_sample: fm- and out-sums are calculated in 2SCALE now and scaled down (via >>SCALE) afterwards (instead of while every single add-operation) - the filter-envelope is now inited with the shorter constructor - todo-list updated 2011-01-07T17:40:47+00:00 Florian Jung flo@thinkpad.(none) 2011-01-07T17:40:47+00:00 urn:sha1:f76e20a3486b31945fd35f6b1a0bd517d6dc176e 2011-01-06T19:16:19+00:00 Florian Jung flo@thinkpad.(none) 2011-01-06T19:16:19+00:00 urn:sha1:e78131ccbbcb81da94e5992f788c6ea291a2050d There are still issues: - filtertest.prog.so: output_note-message which is not true - huge size of the .so (48K are too much!) 2011-01-05T17:40:20+00:00 Florian Jung flo@thinkpad.(none) 2011-01-05T17:25:04+00:00 urn:sha1:e8382521c1a35ad59efea5e8cebb915a67c0008e 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 2011-01-05T14:50:41+00:00 Florian Jung flo@thinkpad.(none) 2011-01-05T14:47:55+00:00 urn:sha1:3d95a25600b5cab8a7e5245b7a581bd8c8939276 The note-compiler can read a program-definition and emits a cpp-file which implements that definition. This implementation is optimized. HOWEVER, the compiler still does not emit a set_param() function. this will lead to a linker error because the function is not implemented (but defined). After adding an empty implementation by hand the emitted compiles well, and also seems to work when used in the synth. TODO: - implement set_param() - compiler must emit a loader-function (which returns a new Note) - use that loader function in the synth
