    Chapter 5 Setting/Changing Sounds (Patches) Changing Tone Release (RELEASE) With the “RELEASE” setting, you can change the decay of the 1st (or 2nd) tone you selected with 1ST SELECT (or 2ND SELECT). By increasing the release time, the sound fades away more gradually at the end of a note, even after the strings stop vibrating.

    With a latch hold, however, pressing the pedal once begins the hold, and pressing the pedal again ends it. On the GR-33, a latch hold is available only when using Arpeggiator. When Arpeggiator is playing and Pedal 3 (HOLD) is pressed, the GR-33 holds the arpeggio being played at the moment the pedal is pressed.

    MIDI OUT External MIDI Sound Device The GR-33 can also serve as a convenient input tool for a MIDI sequencer (a device for recording performances). This chapter explains how to make such steps using external devices (and how to use MIDI functions).
  • Page 87 The latest setting is automatically stored in memory, even after the power is switched off. If the sending Bend Range on the GR-33 is set to “0,” an effect similar to setting COMMON “CHROMATIC” (p. 42) to “Type3” is obtained for the sounds from the external MIDI sound generator.

    The number of the Program Change message that is sent can be freely changed and saved to the patches on the GR-33. (At the time of purchase, Program Change numbers 1 through 128 are assigned sequentially to patches A11 through D84.)

    * The “bank” referred to here is an extended Program Change message set forth in the MIDI specification, and has absolutely nothing to do with the GR-33’s bank number (the second place of the display that is, the “Bank” in “Bank Shift,” “Bank Up, and “Bank Down”).

    A MIDI foot controller such as the FC-200 or Boss FC-50 may be connected (p. 24), using the foot controller to switch patches on the GR-33. In that case, Program Change messages and the like written to the called-up patch for the...

    • Make sure that a sound generator which cannot simultaneously receive six MIDI channels is receiving data from the GR-33 in the Mono mode (p. 88). Procedure for Setting MIDI [TRANSPOSE] 1. Select the patch whose setting you want to change, and press [COMMON] to enter Patch Edit mode.

    Chapter 9 Connecting to External Sound Generators and Sequencers Using the GR-33 as an External Sequencer Input Tool By connecting the GR-33 to a MIDI sequencer (a performance-recording and playback device), even guitarists who don’t play keyboards can perform real-time recording to the sequencer.

    MIDI loop connection is not being used. Creating Realistic Plucked String Instrument Sounds (Data) Using the GR-33 to input parts for guitars and similar string instruments, including harps, koto, and others, makes it possible to achieve voicing and an expressive feeling of dispersions for separately plucked strings that cannot be reproduced with keyboard input.

    3. Use [VALUE] to select “On.” 4. Press [PLAY] to return to Play mode. * This is the setting items for the GR-33 (System mode), and not patch settings, so there is no need to perform a Patch Write operation. The latest setting is automatically stored in memory, even after the power is switched off.

  • Page 96: Practical Use Of Midi Channels

    (p. 86) To achieve faster sound generation and smooth pitch changes, the GR-33 transmits pitch as a combination of Note messages and Pitch bend messages. This means that if the sequencer’s microscope (event list) screen shows only Note messages, what appears on-screen may differ from what is actually performed.

  • Page 104 The MIDI standards inhibit non real-time messages from interrupting an Exclusive one. This fact is inconvenient for devices that support a “soft-thru” function. To maintain compatibility with such devices, Roland has limited the DT1 to 256 bytes so that an excessively long message is sent out in separate ‘segments’.
