My latest music technology find is sfxr. It's brilliant. In a nutshell, it's designed to make those 8bitish old old video game sounds. It's specifically designed for video game designers to get quick sound effects. However, I've found that with a little processing and coaxing, the blips, bleeps and crunchy blurps sound really nice in a psytrance setting. It's too bad it's a standalone program and not a vst instrument.
