MIDI INPUT

RECEPTION DATA

In accordance with the YAMAHA MIDI COMMITTEE

STANDARD and the MIDI 1.0 standard (version 1.0), the

KX88 receives all MIDI data except for the undefined

SYSTEM COMMON MESSAGES $F1, $F4 and $F5, and
their following data bytes.

1. Once $FE has been received, if data or status signals are

not received within 300+10 msec, an error will be as-
sumed, The display will indicate error, and transmission
and reception will stop.

2. For output STATUS BYTES will be abbreviated.

(running status)

3. When a STATUS BYTE with an incorrect number of

DATA BYTES has been received, neither that STATUS

nor DATA byte will be echoed back.

4. A string of up to 20 bytes of user-specified data may be

sent using MANUAL DUMP.

5. Using UNIVERSAL PARAMETER, controller data may

be transmitted inside a user-specified string of up to 8
bytes.

6. By a special function when turning the power on, you

may cancel the abbreviation of STATUS BYTES.
