Using the Local Control setting
If you're using a DAW software with the performance data from the pads and TD-27's
sound generator section, you should turn the Local Control "OFF. "
We need to connect these sections in the following order:
the performance data from the pads0a DAW software0TD-27's sound generator
section.
Since the performance data from the pads and TD-27's sound generator section are
connected internally, such a connection order would normally be impossible. However,
if the Local Control is "OFF, " the performance data from the pads and TD-27's sound generator section will be independent, allowing you to use a
DAW software as shown here in the illustration.
Specifying the HH Note# Border
The note number transmitted when you strike the hi-hat will change depending on the amount of pressure on the hi-hat pedal.
At the factory default value (127), the closed hi-hat note number will be transmitted only if the hi-hat pad is played with the pedal completely
depressed. If you want this note number to be transmitted when the pedal is slightly raised, set this to a value such as "90. "
* In some cases, changing the hi-hat note number border setting might cause a song to play back differently than when it was recorded.
