Virually all examples are GUIfied now, using mainly the instrument mapper.
To look at the examples, use "File/Retrieve from server". Expect everything
that starts with example_ to be an example which you can run and look at.
All synthesis instruments are available in every example.
The instrument flexible_slide also provides an own GUI.
example_stereo_beep is a small example which outputs a 440 Hz sine wave
on one your left speaker, a 880 Hz sine wave on the right.
All others are midi synthesis examples. Fortunately they are quite
convenient to use these days...:
You can use them in conjunction with midisend like that
- start artsbuilder
- choose File/Retrieve from server
- choose either example_instrument_fx or example_instrument_pure:
example_instrument_fx has an additional echo effect.
- go to File/Execute Module
- choose add and add an instrument on some midi channel
- it is now executing and will synthesize the events that come over
the midi bus, so lets create some ;)
- start midisend in a shell window
- you should be able to play on your keyboard now
- you may switch instruments on the fly with the instrument mapper
- for sequencing, you should probably install a midi bus aware
sequencer (see midibus section) - Brahms (which was formerly called
kooBase) for instance is a great tool for working with aRts
You should be careful with the number of maximum voices allowed at
the instrument mapper in the main structure. Perhaps your computer
can calculate more voices than the default (eight) with some instruments,
perhaps even eight are too much... look at the cpu usage to see how
your computer is doing.
