I am building a Barberpole phaser and I am using the H3000-Osc, because I can specify the phase offset. I have 8 such modules, which are offset as 0, 45, 90, 135, 180, 225, 270 and 315 degrees. The ABS works when you feed it a sawtooth; it outputs a triangle with half the frequency. However, not having the same frequency, doesn't help me with what I want to do. The sawtooth LFOs are used to sweep the 8 phasers and the 8 triangle LFOs are used to fade the VCA in and out. If the triangle is half the speed of the sawtooth, then the VCA will not shut completely when the sawtooth reaches the max value and so the Barberpole phasing effect is ruined.
Any idea how to double the frequency of the triangle LFO? A rectifier perhaps?
