You can order as many as you like. We would recommend ordering one at a time because you never know at what point through the revision process you will not want to make any more changes.

We aim to perform all revisions with 1 or 2 working days. All revisions must be manually set up and recorded through analogue equipment. Which takes time. 

No, due to us using analogue equipment and analogue summing with some ITB processing. All mixes or masters must be recorded in real time through analogue equipment.

This can be the case. The initial mix or mastering is set up where we feel it should be. It is fine to deviate away from this slightly but it is good to bare in mind that after 3 or 4 revisions we can be moving too far away from what is right and more to what is wrong. 

A master re-run is when you need to update the mix or change something on your end. This is classed as a master re-run. A revision is when we edit the original audio files you sent for your order.

No you can not and the reason for this is that a master re-run is a change that is required to be made based on a fault on your end. Rather than an edit to our mastering on our end, which is what a revision is used for.
