User manual ROLAND CA-30

[. . . ] Though a single-keyboard instrument, the CA-30 allows you to play monophonic bass organ parts and polyphonic instrument sounds. The PEDAL part usually plays a monophonic bass line that doubles the lowest note you play on the keyboard. You can, however, connect an optional MIDI pedal unit to the CA-30 and play the PEDAL section polyphonically using your feet. Before using this instrument, carefully read the section on the next page. [. . . ] With the following procedure you can set the CA-30 so that the bass notes (of the PEDAL division) are no longer triggered by the keyboard: (1) Switch off the CA-30 and the PK. Note: When the PEDAL section is triggered in this way, it is polyphonic (and can therefore sound several notes simultaneously). Playing only bass notes with your left hand If you prefer to play bass notes without the addition of a MANUAL I register, you need to split the keyboard and switch off all MANUAL I tilt tabs. (2) Press the upper part of any MANUAL I tilt tab whose indicator lights. (3) Press the bottom part of a MANUAL II tilt tab to activate the assigned register. The PEDAL notes now sound in isolation up to the split point for the PEDAL division (which is fixed). Some of the speaking stops on the CA-30 have alternate voices that can be selected and used in performance via the "Voice Palette" feature. For example, you can choose a Spitzflöte 4' rank instead of the Rohrflöte 4' rank assigned to the MANUAL I tilt tab of the same name. Voice Palette was so named because it greatly increases the number of tonal colors at your disposal; there are many more ranks available to you than the number of actual tilt tabs on the instrument. (1) Press and hold the lower part of a tilt tab and watch the MEMORY buttons ([0]~[4]). One of those buttons lights steadily to indicate the rank that is currently assigned to the tilt tab. There may be times when you accompany acoustic instruments that are difficult or impossible to tune. In that case, use the CA-30's TUNE function to adapt its tuning to that of the acoustic instrument: (1) Hold down the [TUNE] button while pressing the [DOWN] button to lower the tuning. The CA-30 allows you to add reverberation to what you play on the keyboard. The reverb effect provides a pleasant reverberation that gives the impression that you are performing in a concert hall, a church, etc. If you like the reverb effect but think it is too prominent or too faint, here's how to change the reverb depth: (2) Press the [DOWN] button to decrease the reverb level, or the [UP] button to increase it. (2) Hold down the [TUNE] button while pressing the [UP] button to raise the tuning. (3) To switch off the reverb effect, press the [REVERB] button once again. (5) Press and hold the [REVERB] button until its indicator starts flashing. (3) Hold down the [TUNE] button while pressing the [DOWN] and [UP] button to return to the CA-30's default tuning (A4= 440Hz). The [TUNE] button only lights when the CA-30's tuning differs from 440. Like all digital instruments, the CA-30 relies on the standard tuning system for western music, where the distance (interval) between any two semitones of an octave is the same. [. . . ] The CA-30 can transmit and receive various MIDI message types, some of which are straightforward, while others require some insight into the workings of the MIDI standard. The CA-30 uses the following MIDI channels for sending and receiving MIDI messages: Note: To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and switch off the power on all devices before making any connections. These channels cannot be changed, so be sure to set the external device to the channel number of the desired CA-30 part. INote messages The CA-30 transmits and receives note messages that translate which keys you pressed on the keyboard. [. . . ]
