+	 * By default, we assume single byte data, which is true
+	 * for system realtime (midi clock, start, stop and continue)
+	 * and active sensing, and handle the other (known) cases
+	 * separately.
+	 * In contrast to the standard, CME does not split sysex
+	 * into multiple 4-byte packets, but lumps everything together
+	 * into one. In addition, CME can string multiple messages
+	 * together in the same packet; pressing the Record button
+	 * on an UF6 sends a sysex message directly followed
+	 * by a song position pointer in the same packet.
+	 * For it to have any reasonable meaning, a sysex message
+	 * needs to be at least 3 bytes in length (0xf0, id, 0xf7),
+	 * corresponding to a packet size of 4 bytes, and the ones sent
+	 * by CME devices are 6 or 7 bytes, making the packet fragments
+	 * 7 or 8 bytes long (six or seven bytes plus preceding CN+CIN byte).
+	 * For the other types, the packet size is always 4 bytes,
+	 * as per the standard, with the data size being 3 for SPP
+	 * and 1 for the others.
+	 * Thus all packet fragments are at least 4 bytes long, so we can
+	 * skip anything that is shorter; this also conveniantly skips
+	 * packets with size 0, which CME devices continuously send when
+	 * they have nothing better to do.
+	 * Another quirk is that sometimes multiple messages are sent
+	 * in the same packet. This has been observed for midi clock
+	 * and active sensing i.e. 0x0f 0xf8 0x00 0x00 0x0f 0xfe 0x00 0x00,
+	 * but also multiple note ons/offs, and control change together
+	 * with MIDI clock. Similarly, some sysex messages are followed by
+	 * the song position pointer in the same packet, and occasionally
+	 * additionally by a midi clock or active sensing.
