What is the General MIDI 2? The upwardly compatible General MIDI 2 ( ) recommendations pick up where the original General MIDI left off, offering enhanced expressive capabilities, and even greater compatibility. Issues that were not covered by the original General MIDI recommendations, such as how sounds are to be edited, and how effects should be handled, have now been precisely defined. Moreover, the available sounds have been expanded. General MIDI 2 compliant sound generators are capable of reliably playing back music files that carry either the General MIDI or General MIDI 2 logo. In some cases, the conventional form of General MIDI, which does not include the new enhancements, is referred to as “General MIDI 1” as a way of distinguishing it from General MIDI 2. What is the GS Format? The GS Format ( ) is Roland’s set of specifications for standardizing the performance of sound generating devices. In addition to including support for everything defined by the General MIDI, the highly compatible GS Format additionally offers an expanded number of sounds, provides for the editing of sounds, and spells out many details for a wide range of extra features, including effects such as reverb and chorus. Designed with the future in mind, the GS Format can readily include new sounds and support new hardware features when they arrive. About the Sounds Contained in a GS Sound Module A GS sound module contains 128 basic sounds (Capital Tones) and a number of Variation Tones. The mapping for the Capital Tones is compatible with Level 1 of the General MIDI System. Capital Tones are stored in Bank 0, while the Variations are stored in Banks 1 through 127. The selection of Variation Tones that are made available will be different depending on the sound module. You should check the manual for any module you are going to use, and familiarize yourself with the sound collection it contains. About the Drum Sets Provided by a GS Sound Module The Drum Channel (ch. 10) provides for the use of several Variation Sets in addition to the basic Drum Set (Standard Set: PC #1). Drum Sets are selected using Program Change messages. The types of Variation Sets that are made available will be different depending on the sound module. Refer to the manual for the module you are using so you know what kinds of drum sets it contains. * If a Variation Tone or Variation Drum Set you have requested is not found in the GS module you are using, the module may not sound at all, or an incorrect sound may be played. ¦ Main Features Superb Playability and Expressiveness Since this standard 49-key keyboard also provides response to velocity, it allows you to express even the finest nuances. In addition, an Octave Shift feature allows you to conveniently shift the soundable range up or down by an octave. Moreover, it is equipped with a pitch/modulation wheel, and provides a jack for connecting a damper pedal. Complete Range of Control Features Since the keyboard provides for sound selections that use combinations of Program Change and Bank Select messages (value for CC 00 and CC 32), you can also select any of the Variation Tones that may be available on a GS sound module. In addition, a variety of continuous controllers (Control Changes) can be assigned to the data entry slider. The slider can then be used for variable control over the desired parameter (reverb or chorus depth, for example) on a GS sound module. Viewing the contents of the LED display allows you to operate easily and precisely. Makes Desk Top Music (DTM) More Enjoyable The PC-70 is very compact, so it requires only a minimal amount of desktop space. The keyboard is sure to become an invaluable part of any DTM setup, since it can be used for real-time or step recording, as well as for practice while listening to “minus-one” playback.
