veets and bluewolfse7en: Thanks much for the suggestion of keeping the A4 as the master - it is working like a charm. I am yet to experiment with the midi machines as I am still trying to get up to speed with the basics though having cut my ElektronWorkFlowTeeth on the A4 has def helped with the fundamentals.
Going to experiment with on the fly sampling into the MD this weekend - can’t wait!!!
Thanks Again - Elektronauts is a great community!
