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. The CA-30 makes it easy to record your own performances. [. . . ] You can activate as many registers as you like. 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. Voice Palette gives you a tremendous amount of added flexibility. 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. Flashing MEMORY buttons indicate locations that contain other ranks you can use instead of the one you get by simply activating the tilt tab. Some MEMORY buttons continue to flash, while one of them lights. Note: If you pressed and held a tilt tab by accident and now see flashing MEMORY buttons, press any other button or tilt tab to leave the Voice Palette selection mode. 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. You can lower the CA-30's overall tuning to as much as 432. (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. You can increase the CA-30's overall tuning to as much as 445. (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. [. . . ] 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. IProgram change, bank select messages In ORCHESTRA mode, pressing a tab to select the desired sound will cause the CA-30 to send two bank numbers (Bank Select MSB & LSB) as well as a program change number. when receiving such a cluster , the CA-30 selects the corresponding sound.
