[philburk]

Here is a working example: https://jsyn.com/jsyn/examples/chebyshev_song.php

Mark working examples at: https://jsyn.com/jsyn/examples/index.php

Use this to build a JAR with no JPortAudio dependencies:
./gradlew build jsynExamplesJar

https://jsyn.com/jsyn/examples/tj_sawfader.php is missing the Ping button and modulation controls!
The code is running as written. The explanatory text is wrong. FIXED

https://jsyn.com/jsyn/examples/fmlab.php - The instrument menu is broken. It flashes then disappears.
Also https://jsyn.com/jsyn/examples/filterfun.php

https://jsyn.com/jsyn/examples/tj_delay1.php - does not echo!
