Prophet T8 Demonstration

YouTube via naokidel | January 17, 2010

"先日、入手したSequential CircuitsのProphet T8を、ちょっとだけ弾いてみました。
あ〜あ、ヘタクソ（＾＾；）

軽いリバーブをかけただけですが、イイ音〜♪
（録画時のレベル合わせがダメだったみたいで、かなりクリップしていますが。）
アフタータッチも鍵盤ごとに掛かる（当たり前か＾＾；）ので、面白いです。
効き具合が、鍵盤によって全然違うけど・・・・

しかし、鍵盤の戻りが悪いところや、変に重い鍵盤があったりして、色々と調整しないといけないです。"

Googlish:
"Recently, the Sequential Circuits Prophet T8 was obtained, and tried to play a little bit.
Oh Oh, crap (^^;)

The only light reverberated sounds good ~ ♪
(The match seemed to be no good at record levels, but rather to the clip.)
Each keyboard aftertouch can take (or course ^ ^) so interesting.
The effectiveness condition, but very different depending on the keyboard

However, what is wrong and the return of the keyboard, or due to the heavy change keys, and many things have to adjust."

10 Big Bass

"The MiniMoog and x0xb0x make a pretty nice combo. Send them through a Moog Bass MUrF, distort slightly, compress and tweak the individual filters of the MUrF and you should get a pretty versatile bass sound."
