82) in use? MIDI receiving by the GR-30 is normally fixed at the Mono mode. (Data is received in the Mono mode even if "transmission in Polv mode" is selected for the MIDI CHANNEL setting.) Also, MIDI Control Change No. 64 (damper pedal) is responds only when receiving in Poly mode. -» Switch on the power while holding down the [+] button to call up the function. ♦ The P-GLIDE and HOLD pedal effects don't work ♦ The Hold and Pitch Glide functions cannot be used when play is controlled by MIDI messages from an external instrument (such as a keyboard). -> Use the controls on the external instrument to apply pitch bending and holds. ♦ Single notes are sounded when MIDI messages are sent from the external instrument, but messages such as Program Change are not received ♦ While the GR-30 is receiving in Mono mode, are MIDI messages being sent to the five channels other than the first channel specified by the MIDI "CHANNEL" setting? MIDI messages other than Note messages and Bend messages must be sent to the first channel. Be sure to send data from the external instrument to the first matching channel, even when the GR-30 is set up to receive data on six channels. • Arpeggiator doesn't work —» Please note that Arpeggiator doesn’t operate when using the Poly Mode Receive function. 87 ■When Sending Performance Data from the GR-30 to an External MIDI Device (sound generator or Sequencer) ♦ No sound from the external sound generator ♦ Do the MIDI channels for sending and receiving match? -4 Make sure the MIDI channels match (p. 71). ♦ The volume level of the external sound generator may have been lowered by a MIDI Volume message (Control Change No. 7) sent from the GR-30. -» Raise the volume on the GK-2A. ♦ Is the volume for the GK-2A or expression pedals too low? -» Use the controls to increase the volume. ♦ The external sound generator plays only one string (some strings can't be heard) ♦ Is the GR-30 using the Mono mode to send data to a sound generator which cannot simultaneously receive data on six MIDI channels? -> For such sound generators, send data in the Poly mode (p. 72). ♦ Is the Bend Data Thin function (p. 79) in use? -4 Do not use the Bend Data Thin function when it is not needed, ♦ Is MIDI "BEND RANGE" set to “1" or "2"? -> When matching with sending and receiving, use as large a value as possible (p. 71). ♦ When "BEND RANGE" is set to "0", the pitch changes in semitone steps. -» Change the setting to a preferable value. ♦ The Note messaaes input to the sequencer don't look like the scale that is actually played ♦ To start playing sounds rapidly and achieve smooth changes in pitch, the GR-30 transmits pitch as a combination of Note messages and Pitch Bend messages. This means that if only the Note messages are examined on the sequencer's microscope (event list) screen, the on-screen information may differ from what is actually performed. -» If continuous pitch change is not required, you can create data that is displayed more faithfully by setting the sending Bend Range to “0.” • Notes in a bass register not on the guitar cannot be played -» Output from MIDI OUT can be transposed as desired by changing the MIDI “TRANSPOSE” setting (p. 76). • The pitch is wrong (out of tune with the guitar) ♦ Is MIDI Bend Range the same for both sending and receiving? -» If the pitch is off, adjust the Bend Range setting (p. 71). • Pitch doesn't change smoothly ♦ Is data being sent in the Poly mode? When transmitting in the Poly mode, pitch changes during chord performances are in semitone steps (p. 72). -4 Play with single notes, or use the Mono mode to send data. 88 Specifications Guitar Synthesizer GR-30 • Weight 1.6 kg 3 lbs 9 oz (excluding the AC Adaptor) • sound generator 1 Part (Mono mode M=6/Poly mode switch-able) • Accessories Owner's Manual AC Adaptor GK Connecting Cable (C-13A, 5 m) • Maximum Polyphony 28 voices • Memory System Setup 1 Tones 384 User Patches 128 (The initial settiinngs are • Options Synthesizer Driver GK-2A GK Connecting Cable (C-13B, 10 m) Preset Patches 128 the same as the Preset Patches) # In the interest of product improvement, the specifications and/or appearance of this unit are subject to change without prior notice. • Effects Reverb Chorus 1 • Display 7 segments 3 characters LED • Connectors/Jacks Mix Out Jacks L and R (also serve as two stereo phone jacks) Guitar Out Jack Guitar Return Jack Bank Shift Jack Expression Pedal Jack GK IN Connector MIDI Connector (IN, OUT) AC Adaptor Jack • Power Supply DC 9 V (AC Adaptor) • Current Draw 440 mA • Dimensions 302 (W) x 274 (D) x 58 (H) mm 11-15/16 (W) x 10-13/16 (D) x 2-5/16 (H) inch- es 89 Roland Exclusive Messages 1.
