If you look just below the bottom right hand corner of each of the charts you will see the key ' o: Yes' and ' x: No' confirming this. Quite simply, a 'o' means the device can handle the feature and a 'x' means it can't.

In the cases where messages are interpreted other than in the most straightforward and obvious manner, we should find some sort of explanatory note to keep us on the right track. It should tell us what MIDI messages the device understands and what messages it can actually transmit. In effect, a MIC is a summary of what a device can do as far as MIDI is concerned. We will use these as examples throughout the article. those funny charts in the back of your latest acquisition's manual that are full of noughts and crosses but don't make a lot of sense! In case you don't know, have a look at Figure 1 and Figure 2 which show the MIDI Implementation Charts (which we will abbreviate to MICs for the rest of the article) for the Yamaha KX88 and FB-01 respectively.
