V3.1

Minor bug fixes related to filter calibration

- - - - - - - -  - - - - - - -  - - - -

V3.0

Version 3.0 brings an exciting new feature: Filter Calibration!
You can now fine-tune your filter response to balance out the natural non-linearities found in original SID chips, especially across different 6581 revisions (R2, R3, R4). Whether you want to match the smoother behavior of a 8580, align multiple 6581s, or even calibrate to a specific character, this new tool gives you the flexibility to get the sound you want.
Details in updated Manual, page 16
Big thanks to RIO for making this possible!
