User manual ROLAND C-180

[. . . ] The instrument sounds can be played via the entire keyboard, while the bass notes can be triggered via the left half of the keyboard. Whenever you play two-hand parts (and perhaps even chords with your left hand), the bass part will sound the lowest note of every chord you play. Record your own performances The C-180 makes it easy to record your own performances. Before using this instrument, carefully read the section on page 2. It provides important information concerning the proper operation of the C-180. To get the most out of the C-180 and to ensure many years of trouble-free service, we urge you to read through this Owner's Manual thoroughly. [. . . ] Note: The [TREMULANT] register cannot be used by itself. It must be combined with at least one other MANUAL register. It has no effect on the BASS sounds. 3. Press the [ORGAN BRILLIANCE] button (indicator goes off) if you want to make the organ sound mellower. 9 Owner's Manual 3. 2 BASS functions Changing the split point As stated above, the left-hand part of the keyboard can be used to add bass notes to your playing. The C-180 scans all keys from the far left up to the split point to decide which bass notes to play. After activating this split function, only the BASS part will sound: it will sound the lowest note you play to the left of the "M" symbol. Playing only bass notes to the left of the split point You can also activate a BASS split function that will mute the MANUAL part to the left of the split point, leaving only the BASS part in the left half of the keyboard: 1. Press and hold a BASS tab, whose indicator does not light, in the off position (press the side closer to the rear panel). Its indicator starts flashing and goes dark when you release the tab 2. Start playing with your left and right hands. This time, the left half of the keyboard can be used to play monophonic bass lines (one note at the time), while the right half allows you to trigger the organ registers (see page 9). To switch off this BASS split mode, press and hold the BASS tab in the "off " position until it flashes again. BASS range (can be changed) MANUAL range (without BASS split) MANUAL range (with BASS split, see below) Note: Do not forget to switch on at least one BASS tab in order to hear the bass notes. Playing the bass notes with an optional PK-5 The C-180's BASS registers can also be triggered via MIDI. Regardless of the interval, very little ambiguity is produced. For the Mean Tone and Pythagorean temperaments, you also need to specify the key in which you want to play: 2. Hold down [CANCEL] and the selected [M] button while pressing the key on the keyboard that corresponds to the tonic of the desired key. Note: When performing in ensemble with other instruments, be aware that, depending on the key, there may be some shifting of the pitch. Please tune to the other instruments in the ensemble. Note: When you play back your recorded song, it will use the temperament that was selected at the time of recording. This may be different from the currently selected temperament. Changing the Reverb level If you like the Reverb effect but think it is too prominent or too faint, here's how to change the Reverb depth: 3. Press and hold the [REVERB] button until its indicator starts flashing. Use the [BASS] slider to set the desired Reverb depth. Selecting different tunings Tuning the C-180 There may be times when you accompany acoustic instruments that are difficult or impossible to tune. In that case, use the [PITCH] control on the C-180's rear panel to adapt the C-180's tuning to that of the acoustic instrument. Turn the [PITCH] control towards the " " to tune the C-180 lower (so that the A4's frequency drops below the default "440Hz" setting). Turn it towards the "#" symbol to tune the C-180 higher. Using different temperaments Like all digital instruments, the C-180 relies on the standard tuning system for western music, where the distance (interval) is the same for all semitones of an octave. [. . . ] Furthermore, the C-180 sends and receives CC11 messages that describe the movements of the EXPRESSION PEDAL. Other control changes that the C-180 transmits are CC07 for the volume (Organ/Orchestral Bass & Layer) and CC91 to communicate the Reverb depth setting (see page 11). Note: Some of the above MIDI messages are only available in Orchestra mode. See also the MIDI implementation chart at the end of this manual. MIDI channels used by the C-180 The C-180 uses the following MIDI channels for sending and receiving MIDI messages: ORGAN mode Rx/Tx channel Manual part Bass part ORCHESTRA mode 12 14 Channel SysEx messages The C-180 also transmits SysEx messages that have a rather complex structure and are thus only meaningful to seasoned MIDI enthusiasts. If you work with the internal Recorder or an external sequencer, it may, however, be possible to record them without even knowing what they look like. [. . . ]
