Not entirely responsive to your specs, but I managed a 3minute modulation
with Moog moogerfooger effects a while back. Here:
"If you have a CP-251 control processor. Turn the LFO rate all the way
down, patch the square wave into the Rate input, and the waveform at the
triangle wave output will be a falling sawtooth wave of 1/60 Hz (actually
the one I measured came in at 55 seconds/cycle - pretty dang close). If
you want a rising sawtooth, run it through the mixer and use the inverting
output."
CP-251
*set LFO Rate to minimum
*connect TRS cable from square out of LFO into the red Rate jack, then a
2nd TRS cable from the triangular out to the phaser.
gives me dead on three minutes on my gear - 180 seconds from the
vertical peak of the rising sawtooth to the next vertical peak.
