I know nothing about musical instruments except the piano :) The other day, a friend was telling me about Korg MicroKORG Synthesizer/Vocoder which her husband bought for their son who is a young musician. She told me it comes with 37 keys and 128 user -rewritable programs and is perfect for the musician looking for a serious yet affordable synthesizer. The perfect one for their son who is a budding musician and she told me that if I need anything for my son, I can check it out at shop micro korg . They have a lots of musical items that I can choose from. I will surely let my son knows since he is also a musical person.
