翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク PPG Wave ： ウィキペディア英語版 PPG Wave The PPG Wave is a series of hybrid digital / analog synthesizers built by the German company Palm Products GmbH from 1981 to 1987. == Background == Until the early 1980s, the tonal palette of commercial synthesizers was limited to that which could be obtained by combining a few simple waveforms such as sine, sawtooth, pulse. The result was shaped with VCFs and VCAs. Wolfgang Palm transcended this limitation by pioneering the concept of wavetable synthesis, where single cycle waveforms of differing harmonic spectra were stored in adjacent memory slots. Dynamic spectral shifts were achieved by scanning through the waveforms, with interpolation used to avoid noticeable 'jumps' between the adjacent waveforms. Palm's efforts resulted in PPG's first wavetable synthesizer, the Wavecomputer 360 (1978), which provides the user with 30 different wavetables consisting of 64 waves each. While the expansive range of sound is evident, the absence of filters results in the Wavecomputer 360 sounding buzzy and thin, which hampered its original commercial viability.〔(【引用サイトリンク】url=http://www.hermannseib.com/english/synths/ppg/history.htm )〕〔(【引用サイトリンク】title=Palm Productions GmbH (PPG) • Wave 2 )〕 Palm's efforts to resolve the apparent shortcomings of the Wavecomputer 360 would result in the creation of PPG's Wave series of synthesizers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PPG Wave」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
