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
