+TEST JACKO OPCODES
+Michael Gogins
+
+This csd tests the Jacko opcodes.
+
+There is a segmentation fault at the end of the performance. This does happen 
+in the Jacko plugin, but it does not affect the performance.
+
+Csound not only writes a soundfile using -o, but also sends realtime audio and 
+MIDI to other Jack clients using Jack connections.
+
+Test MIDI output with:
+
+zynaddsubfx --input JACK --output JACK --auto-connect --sample-rate 48000 --buffer-size 128
