If you are willing to go with sine waves, rather than tri (and I can't see
anyone would prefer a triangle over a sine for modulation purposes), a
quadrature LFO will do the trick. You can generate any phase of sine wave
by mixing sine and cosine waves in the proper proportions; and the
quadrature oscillator generates both.
