Tascam was and still is a very popular brand with musicians involved with home multi-track recordings and Tascam currently has a range of Digital 8-track porta-studios to facilitate this. Another popular product is the MP-GT1(Portable Memory Guitar Trainer) which is a small hand held device used to record songs that can then be slowed down during playback (without altering the key) to assist the guitar player to hear specific notes for learning purposes.
