Like I said, there is no easy way to make 4-hydroxy-2,6-dimethoxybenzaldehyde.
However, if you've read _Pihkal_ enough by now, then you will know that 2,4,6-trimethoxybenzaldehyde is synthetically accessible from 1,3,5-trihydroxybenzene, which is itself accessible from certain natural products.
Also, olivetol is easily methoxylated and formylated to 4-(n)-pentyl-2,6-dimethoxybenzaldehyde.
