I just acquired a new BlueLine M1a for use on a very old fashioned DC system. Works great! But, I have a question. There is an analog control unit that you can buy, wire up, and then have a lot more control over specific sounds, volume, etc.. Is this unit a chore to program?I do not use DCC and so I have no experience with set-up, programming, and other steps that seem to be part of that approach. Is the process reasonable for an amateur like myself? Any experience you could share would be appreciated greatly. Thanks, Dave
