Bipolar (alternates 1.0 and -1.0) band limited impulse generator based on B-Spline interpolation of order 3, integrated twice to create a triangle waveform. In this case, richer sound, but probably turns out not to be as useful (less efficient, distortion issues) as LFTri or an integration of square wave. But also see DPW3Tri.
