Rhythmic LFOs How-To w/ NSI Quad LFO + Expander + Babel

Описание: This video explains how to make rhythmic LFOs with your Eurorack modular system, using the Quad LFO, the Phase Expander, and Babel from New Systems Instruments. You can use these same principles to combine any modulation sources that give you control over the phase of the outputs, and with any maximum/minimum/analog logic module. But note that the behavior of exclusive some (XOR/balanced middle) is unique to Babel.

Module descriptions:

The Quad LFO is an 8 HP analog sine core oscillator, giving four independent sine wave outputs. Each of the outputs ranges from nearly stopped to about 23Hz, covering the full sub-audio range and just dipping into the low audible frequencies. Each has linear voltage control as well, meaning that an increase in control voltage gives a proportional increase in output frequency. While each LFO is initially configured as a sine wave, there are four jumpers on the back to switch between sine and pulse wave outputs. This can be handy for using one of the four LFOs as a clock, or if you just want a square wave LFO for some other reason.

The 6 HP associated expander gives you three more LFO outputs, in a controlled phase relationship with the LFO to which they are connected. That is, each of the outputs is delayed by a certain percentage of the LFO cycle. The first output ranges from 0–180º, or from unison to a half cycle delay. The second ranges from 90–270º, or from a quarter cycle to three quarter cycle delay. And the last ranges from 180–360º, or from a half cycle to a full cycle delay. The phase expander can be useful for creating interesting rhythmic modulations, or when the LFO is configured as a square wave, giving you three phases of a sine wave LFO synced to a clock.
