+ * So we need to interpret these here before sending them on.
+ * 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.
