Hi Bill I have 2 of them they are the Roland MC-909 and MC-307 groove boxes. They are more than just a drum machine they are synths as well. The mc-909 has sampling as well. They are great machines. They are designed mainly for the electronic musician. ----- Original Message ----- From: Bill To: ddots-l@xxxxxxxxxxxxx Sent: Wednesday, February 4, 2015 1:38 PM Subject: [ddots-l] Your Vote for most Accessible Drum Machine A blind musician who is not subscribed to this list asked me to ask you: Which drum machine do you consider to be most accessible to a blind user? I myself do not own a drum machine and I really have no idea. Thanks, Bill Regards, Bill Bill McCann Founder and President of Dancing Dots since 1992 www.DancingDots.com Tel: 610-783-6692
