Seiko DS250 – 1980 年代一种奇怪且极为罕见的 Additive 合成器，J.M Jarre 在他的 Rendezvous 专辑中使用。 DS250 内置了一组预设，它允许您通过按双功能键选择第 1 层和第 2 层来堆叠两个预设；按下这些按钮有点尴尬，所以我们的版本只有两组 16 个预设选择按钮，这更容易。 D-250 依靠某种形式的加法合成来创造它的声音，并产生不干净和原始的音调，而是具有美妙的泥土、有机和颗粒状的声音，具有许多特征。
Seiko DS250 – A strange and extremely rare Additive synthesiser from the 1980’s and used by J.M Jarre on his Rendezvous album. The DS250 has a set of presets built into it and it allows for you to stack two presets by pressing a dual function key to select layer 1 and layer 2; it is a little awkward pressing these buttons, so our version just has two sets of 16 preset select buttons which is much easier. The D-250 relies on some form of additive synthesis to create its sound and produces tones that are not clean and pristine, but instead have a wonderful earthy, organic and grainy sound that have bags of character.
