Russ way to go.....I will be at AJ's "Lab" next week with Fran to play one myself.....& if the shoe fits I'll be wearing it for sure.....AJ is tops when it comes to support on Ketron products I have been dealing with him for years and he ALWAYS goes the extra mile and way beyond for his customers.....he is also super knowledgeable & knows these KB's In & Out..

I would definitly install the Vocalizer it will add a new dimension to your music ....only if you use it properly...Uncle Dave is a Master with one & has taught me many unique vocalizer techniques that really make a song come to life.....its not too difficult once you put your mind in the right way of thinking when you sing. Being your a old MS player Im sure you'll do OK with the SD5...Good Luck Russ and let us know how you progress along OK?

Take Care
