up sound generator mode" (p. 72)
●
If an exclusive message initializing the sound generator is inserted (e.g., on your sequencer) at the
beginning of a song, the sound generator will be initialized before the song begins.
■
I want to transmit the data for only a specific parameter to the
computer (sequencer software)
●
In addition to bulk data, which transmits a group of parameters together, the SD-90 can transmit “individual
data” for separate parameters. If a bulk dump would involve too much data, you can try using this
“individual data.”
Individual data lets you create data without having to look up each system exclusive message, and
provides an efficient way to create (for example) song data that contains exclusive messages.
"Transmitting individual data"
■
In some cases, depending on the environment in which the unit is
installed, the surface of the panel may sometimes feel rough and
grainy.
This is due to an infinitesimal electrical charge, which is absolutely harmless. However, if you are
concerned about this, connect the ground terminal (p. 12) with an external ground. When the unit is
grounded, a slight hum may occur, depending on the particulars of your installation. If you are unsure of
the connection method, contact the nearest Roland Service Center, or an authorized Roland distributor, as
listed on the "Information" page.
Unsuitable places for connection
• Water pipes (may result in shock or electrocution)
• Gas pipes (may result in fire or explosion)
• Telephone-line ground or lightning rod (may be dangerous in the event of lightning)
■
Howling could be produced depending on the location of microphones
relative to speakers.
This can be remedied by:
• Changing the orientation of the microphone(s).
• Relocating microphone(s) at a greater distance from speakers.
• Lowering volume levels.
