+description: Process audio using JACK.
+notes: >
+  This can be used to receive audio from JACK by connecting only input ports.
+  It can be used to output audio to JACK by connecting only the output ports.
+  Or, you can use it as a filter with something like JACK Rack by connecting
+  both output and input ports to send and receive.
+  You can configure as many channels as you need and repeat the in_1/out_1
+  pattern for as many channels as you have configured.
+  If you are using a MLT consumer that uses ALSA, then you should start
+  jackd with the dummy driver, e.g.: jackd -ddummy -r48000 -p2048.
+  The MLT JACK client name uses the format: mlt{pid}.
+bugs:
+  - >
+    MLT cannot automatically adapt to the sample rate at which JACK is configured.
+    Please make sure they are configured the same.
+  - Does not automatically reconfigure to the number of channels requested by consumer.
+  - Some effects have a temporal side-effect that may not work well.
