MusicRow has recently released a new plugin that emulates scratch sounds. The plugin can be used as an insert effect on the track that you want to scratch.
Vinyl Boy brings DJ scratching directly to your studio, with the advantage of precise midi treatment for the exact results you need. With Vinyl Boy you can scratch your audio tracks in real time- just open it as an insert effect on the track that you want to scratch, and use your modulation wheel for the authentic feeling and touch of vinyl scratching!
