Looks like all SID registers (except for the 3rd voice) are write-only. Here is a solution I found on the csdb forum:

you have 2 options(others will bring up more:)

1. you turn on d000 ram, and call the player like that. then you can read the values from ram, and write them back to the sid regs afterwards. but this will distort the player's output. (mostly noticable to music people, or at specific players)
2. you recode all sta $d400 (generally any sid write) to jsr someroutine, where someroutine can store the value and then update the sid register. cubic player does this, it automatically recodes every player.

I think the second option is the safest. So we need a script that recodes every write to $d400-$d7ff on a .sid file into a jsr that stores the value somewhere on RAM (to be defined) before.
