01/W MIDI Implementation Chart

Revised: 98Jul29

I only have access to the MIDI Implementation Chart for the 01/Wpro and 01/WproX. There may be differences between this Chart and those of other models.

Notes 1. Transmitted and recognized when CONTROL = ENA in Global Mode. 2. Transmitted and recognized when EXCLUSIVE = ENA in Global Mode. 3. Transmitted and recognized when PROG CHANGE = ENA in Global Mode. 4. Transmitted but not recognized when using Internal Clock. Not transmitted but recognized when using External Clock. 5. Transmitted and recognized when AFTERTOUCH = ENA in Global Mode. 6. Only Sequence Data will be transmitted and recognized

Basic Channel
This is the same as the Global Channel (Global is Korg terminology). This is set in Global Mode on Page 0. The chart shows the range of channels the 01 can have when the power is turned on ("Default") and the range of channels it can be changed to ("Changed").

Mode
Mode 1: Omni On, Poly
Mode 2: Omni Off, Poly
Mode 3: Omni On, Mono
Mode 4: Omni Off, Mono

Note Number
The range of notes the 01 can send and play. The 01 can only send as many notes as there are keys (unless you are sequencing). However, the Sound Module in the 01 can play all 128 MIDI notes (if you can find a way to send those notes in over MIDI).
"True Voice" means the number of different notes that can be played.

Chart interpretation example:
The 01/WproX has 88 keys.
With no transposition, it will output MIDI note numbers 33(A0) - 120(C8).
You can transpose it down an octave, making the note range 21(A-1) - 120(C8).
You can lower it one more octave using pitch bend, making the note range 9(A-2) - 120(C8).

Velocity
Shows if the 01 is velocity-sensitive and whether it uses Note Off messages (a Note On message with velocity = 0 is another way to turn a note off).
The 01 is velocity sensitive.
The 01 does NOT send or recognize Note Off messages.

Aftertouch
Key's (Polyphonic Key Pressure)
Ch's (Channel Aftertouch)

System Common Messages

MIDI Time Code Quarter Frame (F1h)
Song Position Pointer (F2h)
Song Select (F3h)
(reserved) (F4h)
(reserved) (F5h)
Tune Request (F6h)
End Of Exclusive (EOX) (F7h)

System Real Time Messages

Synchronization messages

MIDI Timing Clock message (F8h)
Sent by a master unit to all slaves to synchronize sequencing tempos. This message, also called a "clock tick", is sent continuously at a rate of 24 messages per quarter note. Timing Clock messages may be sent only after a Start or Continue message, or may be sent at all times, even after a Stop message.

Given a rate of 24 ticks/messages per quarter note, we can calculate the number of ticks for all note values. The shortest note value we can have is a 64th-note triplet, which takes one tick.

(reserved) (F9h)
Start (FAh)
Continue (FBh)
Stop (FCh)
(reserved) (FDh)

Other Real Time messages

Active Sensing (FEh)
Used to detect and maintain a hardware MIDI connection.

System Reset (FFh)
Re-initializes the receiver/slave. Should never be re-sent out MIDI Thru.
