MIDI Implementation 

Notes:

 See the MIDI Mapping config option for details on how MIDI notes are mapped to LDB-1se instru-

ments. When no patterns are running, incoming MIDI notes are played immediately, otherwise they are 
played at the selected tempo (quantized). MIDI note off messages, and zero velocity note on messages 
are ignored. 

Song Select Messages:

 The LDB-1se will respond to MIDI song select messages that have a song number 

of 1 to 16. The selected in the current bank pattern will play. 

Real-Time Messages:

 The LDB-1se will respond to the below MIDI system real-time messages. The LDB-

1se can be configured to ignore clock messages or all transport messages. 

Clock:

 Overrides the internal clock.  

Stop:

 Stops the currently playing song or pattern immediately. 

Start:

 Starts playing the current song or pattern at the beginning. 

Continue:

 Starts playing the current song or pattern at the point at which it stopped. 

Song Position Zero:

 Sets the song position to the beginning of the song, so that a Continue message will 

start it playing from the beginning. This message is handled because some MIDI implementations only 
send one Start message and subsequent messages consist of a Song Position Zero message then a Con-
tinue message. Messages that attempt to set the song position to a point other than zero are ignored. 

 

 

Memory 

The LDB-1se contains non-volatile memory. That is, it remembers data even with no power. 

The only thing that is automatically saved to non-volatile memory is the current bank number. All other 
data will only be saved when you explicitly save it. That includes patterns, songs, triggers, and configura-
tion options. 

 

 

Factory Reset 

To reset all configuration values to the factory defaults, Hold the Start and Mode buttons while powering 
on the machine. 

To reset all patterns to the factory defaults, Hold the Start and Set buttons while powering on the machine. 

To reset both configuration values and all patterns to the factory defaults, Hold the Start, Mode, and Set 
buttons while powering on the machine.
