Introduction A NDROMEDA A6 R EFERENCE M ANUAL 15 I NTRODUCTION There was a time when most of us thought that analog synthesis was dead. Yeah, there were a few new analog instruments – and rather decent ones, at that – that have come and gone over the past few years. They were glimmers of hope that the robust, full and rich sounds of the analogs[...]
