MIDI = control signals
Audio = sound

This patch routes MIDI control signals from JackRack into your wavetable 
synth. You might trigger some random notes this way, but you won't be hearing 
any nice reverbs. You want to route JackRack's Audio output to the alsa_pcm 
input (i.e. NOT the MPU-401) using the previous (Audio) tab.
