jack-oscillator

• Single oscillator synthesizer with traditional waveforms for JACK (Jack Audio Connection Kit)

• This is a single-oscillator lightweight synthesizer, with traditional waves (sine, square, sawtooth, triangle). You can select the form, amplitude and envelope of the wave.

Compilation

• In order to get this software working, JACK Server is required. Often you can find a jack or jack2 (jackdmp) in your distribution packages. Official site: http://jackaudio.org .

• There's no a configure file, just a simple Makefile, with -ljack -ldl -lrt -lm -lpthread flags.. if you can't compile try installing these libraries (dev headers).

Usage

• The program is composed of only a main binary, start it.

• Now you can use a jack frontend (such as qjackctl) to connect the ports (you have a mono audio out and a midi input).

• If your midi controllers works with ALSA sequencer instead of JACK midi driver, try using 'a2j -e' (provided by a2jmidid) to convert ALSA ports in MIDI ports and viceversa.

• The client needs a name, you can provide in command line, otherwise the client will ask you on start, and after that, a simple shell will appear.

    $ simple_osc osc1
  
    Sample Rate = 44100/sec
    Hi! if you need help, type h
    To close the synth, type q or ^D
    osc1: h
  
    h -> help
    c -> change channel
    W -> change waveform
    A -> set amplitude
    a -> set attack time and attack amplitude peak
    d -> set decay time
    s -> set sustain
    r -> set release time
