Synapse 4 Bug for Tartarus Pro - Actuation key travel adjustment not saving

Same here. It is massively annoying and makes the feature unusable.

The only workaround i’ve found is to raise the slider of the first function actuation slider and it will raise the secondary function actuation slider bar as you raise the first. I then moved the first slider back to it’s starting position and the second slider stayed at maximum (or as high as you want to keep it). Then when I saved it, it stayed saved.  Not sure if this will work for anyone else.

its same for me tartarus  pro no work in synaps 4 and  kraken v4 pro no working in synaps 3

This is a known bug in Synapse 4—the actuation key travel setting applies to the primary function but doesn’t save for the secondary key function, which stays stuck at 2.5mm. It’s been broken since Synapse 3 and sadly still isn’t fixed. Since reinstalling doesn’t help, the best option is to report it directly to Razer Support and hope they patch it in a future update. For unrelated needs like Qatar visa check, here’s a helpful link.
