 - **Name:** Panning setting

-- **Description:** Changes the volume balance for the left and right output channels. `N01` is left, `N10` is center, `N1F` is right. ~~Intermediate values are supported only by the T6W28 chip; it effectively decreases the output volume in one of the output channels, but never silences it unless `N01` or `N1F` is used.~~ The special `N00` silences both channels.

 #### VGM Logging
 
 Under the **Tracker** menu is a new option called "Log VGM File...". Select it to save a VGM file, then play any song to start logging all audio events, and stop the player to finish logging.

+## Compatibility
+
+SnevenTracker modules (`.snm` files) share the same format with `.ftm` and `.0cc` files but are incompatible with them. Copying and pasting of frames and patterns still works across these trackers.

-SnevenTracker (SN76489 Tracker) is a fork of FamiTracker version 0.4.6 that
-emulates the Texas Instruments SN76489 sound chip, which is used in a wide
-variety of computers and gaming consoles. The project's ultimate aim is to
-implement multiple sound chips in a more modular manner than 0.4.6, in order to
-provide insight into eventually supporting them in

-### Notes
-
-- Replaces 2A03 with SN76489, removes all expansion chips
-- Tracker functionality chiefly based on MOD2PSG2
-- Produces `.snm` files, zero compatibility with FamiTracker or 0CC-FT except
-  for clipboard formats
-- Should support multiple master clock rates and both versions of the LFSR,
-  also Game Gear stereo functionality
-- Should support two instances of the SN76489, plus an extra sound chip
-- Should support VGM logging (may be backported from 0CC-FamiTracker), KSS
-  export is planned
