Mono ==== Hello. This is an excercise in subtractive synthesis. My intent is to write a bandlimited oscillator, a 4-pole low-pass filter and an envelope generator that run in real-time, and to have a TB-303- inspired graphical user interface on top of that. Current features: ----------------- [yes] oscillator (though not yet properly bandlimited) [yes] 4-pole all-pole low-pass filter [yes] ADR envelope generator [yes] single pattern sequencer [yes] butt-ugly GUI [yes] real-time audio output on Linux, IRIX and Solaris Current problems: ----------------- * oscillator is not properly bandlimited * sliders aren't quite calibrated * butt-ugly GUI :) * minor malfunctions (bugs? features?) * there is no sequencer button feedback during playback * there are no tones synthesized during sequencer programming * audio hardware configuration is selected at *compile* time * sound file write is selected at *compile* time and doesn't work with RT audio output Requirements: ------------- * Sonic Flow version >= 0.1.3 * Gtk-- version >= 1.1.8 * libaudiohw version >= 0.2.0 * libsoundfile version >= 1.0.0 * libpbd version >= 1.0.0 * libsigc++ version >= 0.8.5 * GTK+/Glib version >= 1.2.5 * POSIX threading (libpthread; comes with Linux for example) * C++ Standard Template Library (comes with GCC 2.95 for example) Download: --------- http://download.sourceforge.net/mono/mono-0.1.0.tar.gz Configuring audio output a.k.a. What to do after downloading: ------------------------------------------------------------- As of now, the audio configuration process is not that nice; you have to be a nerd in order to succeed. Namely, (1) selecting between RT audio output and file output - file src/engine.cc, at end of function Msyn_Engine::build_network() - output file is "mono_out.wav" (see Msyn_Engine) (2) selection of RT audio driver - file src/audio_output.cc, function Msyn_Audio_Output::open_audio() - I've tested ALSA and OSS output so far (3) run configure and make (4) run src/mono (5) thumbs up!
