I did a search for tape player wind-up and wind-down effects and stumbled upon Tape Stop by kiloHearts. I picked it up, played nonstop for a couple days and wanted to share my enthusiasm in this mini user review.
Very simple, yet powerful – not many buttons or controls, but limitless in the sense that it spins-down and speeds-up whatever audio you feed into it. It's a fantastic tape transport effect emulation. I can feel the motor. I can hear the magnetic flakes jumping off the tape. Nice price. Useful. Fun. Use this wisely, and it could really spice up a track:
GUI couldn't be better. .. certainly doesn't get in the way. LOL.
