Fasttracker II Clone has been released in version v2.25.

It is an open-source re-creation of the DOS classic Fasttracker II, a tracker program for composing music in module format (XM).

The new version mainly brings further sinc interpolation improvements and a re-added quadratic spline interpolation.

• Further sinc interpolation improvements
• Re-added 3-point quadratic spline interpolation (why not)
• Small tweak to the tracker scope interpolation (in quadratic/cubic/sinc mode)
