Thanks a lot, @rd2rk! That was exactly the missing piece. I hadn’t explicitly assigned the parameters (Drive, Channel Volume) to Snapshots using the right-click → Snapshots option in HX Edit. Once I did that and saw the value turn white and enclosed in brackets, everything started working perfectly. I confirmed that: Each snapshot now retains its own values for Drive and Channel Volume. Switching snapshots properly recalls the correct values. Saving the preset after adjustments makes them persistent, as expected. I really appreciate your clear and concise explanation — it saved me hours of frustration. Hopefully this helps others who run into the same issue with firmware 3.80. Thanks again!

Hardware: Helix LT Firmware/Editor: Firmware 3.80 (build 7d01f5e), HX Edit 3.80 OS: macOS Sonoma on MacBook Pro M2 (no hub, direct USB-C to USB-A adapter) Global Settings: Snapshot Edits = Recall Attach Preset: Can upload .hlx test file if needed Bug description: When changing a parameter (e.g., Drive, Channel Volume) in the Amp block between two snapshots, Helix does not store the values individually per snapshot. After saving, both snapshots retain the same value — always the last one edited. Steps to reproduce: Create a brand new preset Insert a single Amp block (e.g., Brit Plexi Brt) Go to Snapshot 1 → Set Drive to 5.0 Save the preset Go to Snapshot 2 → Set Drive to 7.0 Save again Switch back to Snapshot 1 → Drive is now also 7.0, not 5.0 Same happens with Channel Volume or any other amp parameter. Additional notes: No controller assignments are present (confirmed via HX Edit and on-device) Volume/Pan block was also tested but its Gain parameter is not snapshot-compatible (expected) Same behavior occurs with other amp models Factory Reset has been performed (FS 9+10) Bug still occurs with absolutely clean preset HX Edit and firmware both up to date (v3.80) Snapshot Edits setting is correctly set to Recall Please confirm if this is a known bug in version 3.80 or if anyone has found a reliable workaround (other than duplicating amp blocks per snapshot). Any help is appreciated
