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.
After searching for many years to find one of these illusive keyboards I was immediatly struck by its great set of presets, but I thought it was let down by not being velocity sensitive – So that was the first thing we added to Castle Instruments version. I also thought it could benefit from resonant filters, so we added those and also added velocity modulation to allow control of the Filter Cutoff and resonance; this really added so much expression to the sounds. We also added multiple filter types which can be selected from the filter menu on the interface.
We also added controllable ADSR for amp and filter, Hi-Pass filters, and MIDI syncable LFO’s; all of these extra features take the sounds way beyond what can be achived with just the hardware synth. Of course our version has the original sounds from the hardware DS-250 and we created the factory presets for you in the preset folder, but it is great to be able to go way beyond what the hardware can do and explore new sounds – sort of like if Seiko had added all these new features to their original hardware.
Our version also has two random patch generators – one for each preset layer which makes it easy to throw some chaos theory into your patch creation and just hit randomise until you get something you like.
Also included is a full effects section including: Chorus, Phaser, Flanger, Tape saturation/warmth, Reverbs, MIDI syncable Delays and an arpeggiator.
The Castle Instruments DS-2500 is great for taking a journey into the strange and digital world of additive sounds and textures who’s roots are firmly entwined in the original sounds from the DS-250 hardware and comes with 100 presets and 30 MULTI’s to get you started.

Randomisation System
2 Layers (16 Voices per Layer)
41 Filters with LFO

精工DS250-1980年代奇怪而极为罕见的添加剂合成器，由JM Jarre在其Rendezvous专辑中使用。DS250内置有一组预设，通过按双功能键选择第1层和第2层，可以堆叠两个预设。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，这更加容易。
D-250依靠某种形式的加性合成来产生声音，并产生不干净原始的音调，而是具有美妙的泥土，有机和粒状声音，并具有特色。
经过多年寻找这些幻觉键盘之一后，我立即被其出色的预设吓了一跳，但我认为它对速度不敏感而感到失望-所以这是我们在Castle Instruments版本中添加的第一件事。我还认为它可以从谐振滤波器中受益，因此我们添加了这些滤波器，还添加了速度调制以控制滤波器的截止频率和谐振。这确实增加了声音的表达。我们还添加了多种过滤器类型，可以从界面上的过滤器菜单中进行选择。
我们还为放大器和滤波器，高通滤波器和MIDI可同步LFO添加了可控制的ADSR。所有这些额外的功能使声音听起来超出了仅通过硬件合成器即可实现的功能。当然，我们的版本具有硬件DS-250的原始声音，并且我们在预置文件夹中为您创建了出厂预置，但是能够超越硬件的功能并探索新的声音，这是非常棒的-就像精工是否将所有这些新功能添加到其原始硬件中一样。
我们的版本还具有两个随机补丁生成器-每个预置层一个，可以轻松地将一些混乱理论带入补丁创建中，只需按随机化，直到获得您喜欢的东西即可。
还包括一个完整的效果部分，包括：合唱，移相器，镶边，磁带饱和度/温暖，混响，MIDI可同步延迟和琶音器。
Castle Instruments DS-2500非常适合进入附加声音和纹理的奇异数字世界，其根源牢固地缠绕在DS-250硬件的原始声音中，并具有100个预设和30个MULTI，可以帮助您入门。 。
特点：
110个预设
30个多重
随机化系统
2层(每层16个音色)
41个带有LFO
琶音器的滤波器
7个全局效果
卷积混响
