    Basic Structure

    The Seven Functional BlocksThe S90 XS/S70 XS system consists of seven main functional blocks: Tone Generator, A/D Input, Sequencer, Arpeggio, Controller, Effect, and Audio Record/Playback.

    AWM2 (Advanced Wave Memory 2)This instrument is equipped with an AWM2 tone generator block. AWM2 (Advanced Wave Memory 2) is a synthesis system based on sampled waves (sound material), and is used in many Yamaha synthesizers. For extra realism, each AWM2 Voice uses multiple samples of a real instruments waveform. Furthermore, a wide variety of parametersenvelope generator, filter, modulation, and otherscan be applied.

    Troubleshooting

    Tone Generator BlockThe tone generator block is what actually produces sound in response to the MIDI messages received from the Sequencer block, the Controller block, the Arpeggio block and from the external MIDI instrument via the MIDI IN connector or the USB connector. The MIDI messages are assigned to sixteen independent channels, and this synthesizer is capable of simultaneously playing sixteen separate parts, via the sixteen MIDI channels. However, the sixteen-channel limit can be overcome by using separate MIDI ports, each supporting sixteen channels. The tone generator block of this instrument can handle MIDI messages over Port 1. The structure of the tone generator block differs depending on the mode.

    Tone Generator Block in the Voice Mode

    Only one MIDI channel can be recognized in the Voice mode because only one part is available in this mode. This status is referred to as a single timbre tone generator. A Voice is played from the keyboard, using a single part. To set the MIDI receive channel for single timbre operation (Voice and Performance modes), use the Basic Receive Ch parameter (page 137) in the Utility MIDI display. In the Voice mode, the instrument recognizes only data over MIDI Port 1.

    NOTE If you want to play song data on an external MIDI sequencer or computer consisting of multiple MIDI channels, make sure to use the Multi mode (page 6).

    A program that contains the sonic elements for generating a specific musical instrument sound is referred to as a Voice. Internally, there are two Voice types: Normal Voices and Drum Voices. Normal Voices are mainly pitched musical instrument type sounds that can be played over the range of the keyboard. Each Voice consists of up to eight Elements (Normal Voice) or up to 73 keys (Drum Voice). An Element or Drum Key is the basic and the smallest unit for a Voice. This means that only one Element or key can produce the musical instrument sound. In addition, a Normal Voice can produce the realistic sound or various types of sound by combining multiple Elements. Each Voice is created by editing parameters unique to each element/key (Element Edit parameters/Key Edit parameters) and parameters common to all the elements/keys (Common Edit parameters). In Element Edit and Key Edit, you can edit the parameters only on the S90 XS/S70 XS Editor.

    NOTE For instructions on editing a Normal Voice, see page 34. For instructions on editing a Drum Voice, see page 58.

    Normal VoicesThis is a Voice which is played conventionally from the keyboard, with standard pitches sounding for each key. A Normal Voice consists of up to eight Elements. Depending on the settings in the Voice Edit mode, these Elements are sounded simultaneously, or the different Elements are sounded according to the note range, velocity range and the XA (Expanded Articulation) settings. The illustration is an example of a Normal Voice. Since the six Elements here are distributed across both the note range of the keyboard and the velocity range, a different Element sounds depending on which note you play and how strongly you play it. In the note distribution, Elements 1 and 2 sound in the lower range of the keyboard, Elements 3 and 4 sound in the middle range, and Elements 5 and 6 sound in the higher range. In the velocity distribution, Elements 1, 3 and 5 sound when playing the keyboard softly, while Elements 2, 4 and 6 sound when playing it strongly. In a practical example of this in use, a piano Voice could be composed of six different samples. Elements 1, 3 and 5 would be the sounds of the piano played softly, over the respective note ranges, while Elements 2, 4 and 6 would be strongly played sounds, for each respective note range. Actually, the S90 XS/S70 XS is even more flexible than this, since it allows up to eight independent Elements.

    Troubleshooting

    Drum VoiceDrum Voices are mainly percussion/drum sounds that are assigned to individual notes on the keyboard. A collection of assigned percussion/drum waves or Normal Voices is known as a Drum Kit. Unlike Elements, the Drum key is equivalent to the corresponding note, meaning that you cannot change its range. Drum or percussion sounds are assigned to each Drum Key. You can create various types of Drum Voices by changing the drum or percussion sound assigned to each key and edit the parameters such as pitch and EG.

    Expanded Articulation (XA) is a specially designed tone generation system that provides greater performance flexibility and acoustic realism. This feature, adopted from the MOTIF XS synthesizer, allows you to more effectively recreate realistic sound and natural performance techniquessuch as legato and staccatoand provides other unique modes for random and alternate sound changes as you play.

    Realistic legato performanceConventional synthesizers recreate a legato effect by continuing the volume envelope of a previous note on to the next one, in the mono mode. However, this results in an unnatural sound different from that of an actual acoustic instrument. Like the technology of the MOTIF XS series, the S90 XS/S70 XS
