Because Cakewalk Pro Audio software will be used for
sequencing, rather than the XP-80's internal sequencer, many of the
control keys on the XP-80 will not be used. This information
covers only the basic key functions of the XP-80 for general
purposes. For further details, please consult the Roland manual.
||Disk Drive: 3.5" 2DD/2HD disks can be
used. Press the eject button located at the bottom right
of the disk drive to remove a disk.
|Volume Slider: This slider adjusts the
overall output level for headphones and rear output jacks.
|C1 & C2 Sliders: Various parameters
may be assigned to the sliders.
|Pitch Bend / Modulation Lever: Moving the
lever from left to right controls pitch bend. Moving the
lever forward controls vibrato. Other control parameters
may be assigned as well.
[Filter/Env]: Press this button ON when modifying filter
and/or envelope settings in real time using the four sliders
(Cutoff--modifies brightness, Resonance-- modifies resonance,
Attack--modifies attack time, Decay--modifies decay time) (pp. 28,
[Level]: Press this button ON when adjusting volume balance
in real time using the four sliders (pp. 28, 32).
The buttons in this section allow you to assign various functions
to the keys of the XP- 80's keyboard.
- [RPS]: Switches RPS on/off. Realtime Phrase Sequencing

buttons while holding down [Transpose] allows you to set the
desired amount of transposition (p. 38).
Mode & Effects
The buttons in this section select modes. The button
indicator of the selected mode will light (p. 20). Sound
sources (patches) are selected in this section: Performance
mode, Patch mode, Rhythm mode, GM mode (General MIDI).
- [Perform]: Performance mode contains various groupings of
patches (voices). Individual patches may be changed.
This particular mode is primarily used when utilizing the XP-80's
- [Patch]: Selecting this mode makes available the five
individual patch groups of 128 voices each: User, PR-A,
PR-B, PR-C, GM. (See other handout.)
- [Rhythm]: Rhythm Set mode makes available the ten
percussion instrument sets. (See other handout.)
- [GM mode]: To set General MIDI mode, hold down [Shift] and
press [Perform]. [Perform], [Patch] and [Rhythm] indicators
will not light. This special mode makes the XP-80 function
as a GM-compatible sound source.
- [Sequencer] / [Chain Play]: Selecting Sequencer mode and
Chain Play mode determines how the sequencer will operate.
One of these modes has to be selected for the internal sequencer
to operate. (The internal sequencer will not be used in this
class.) Sequencer mode is selected for recording, playback
and editing of a song. Chain Play mode allows you to select
the order of song playback.
- [System]: System mode is for determining global XP-80
settings such as tuning, display contrast and how MIDI messages
are received. Please do not change any settings in
- [Utility]: Utility mode allows the saving and transmitting
of sound source settings--not a key you will use often ...
- [Disk]: This mode is used for saving/loading data to/from
the floppy disk drive. It also allows access to disk
format, which prepares a disk for MIDI data storage.
- EFFECTS: The buttons in this section turn their respective
internal effects on/off.
- [EFX]: = Effects. Switches the multiple effects unit
on/off (p. 40).
- [Chorus]: Switches chorus on/off (p. 40). Chorus
provides a fuller-sounding timbre.
