Modulate one clock with a triangle wave and the other with the wave inverted. The PAiA string keyboard did this. There's a web site somewhere that has all of the variations used in string synths, the Dimension D and so on.</div><div><br class=""></div><div>I suppose you could run one at the highest possible frequency/shortest delay time and have the second, modulated BBD in parallel.
