Do you mean:
When I arm an instrument track for recording, the volume of it drops.

Or,
When I compare the playback of the instrument track to when I monitor to record on it, the volume changes.

Please be more specific as the the nature of your issue.
Thanks.

thank you
tha later is my problem

Maybe you are monitoring at a much higher volume level than your record level, ?

are there any places to adjust these types of issues in studio 1
thank you
i am new and still finding my way

When you have Dropout protection set to anything else but Minimum, try to set it back to Minimum.
If that solves it, you probably have a plugin in the low latency monitoring path of the instrument, that is introducing a latency > 3 ms.

The audio signal of Instruments with Low latency monitoring for instruments enabled, will bypass plugins introducing a latency > 3 ms when monitored.

Instruments within a Low latency monitoring for instruments path, have a green instead of blue activate button and a Z on their channel(s). Inserts on the channels that are included in the low latency path also have a green activation button. Inserts that are (partially*) bypassed ( > 3ms) are lacking a clear visual indicator of their current state and are just blue.

* When on a bus receiving low latency and non low latency paths.
