Modbox

Compact dual LFO

The Modbox is a tempo syncable modulation source with a three-phase LFO, CV skewable LFO, sample and hold, and a white noise generator.

LFO 1 is a three-phase LFO with independent outputs for each phase which are set at 0, 120, and 240 degrees. Shape can be switched between Sine, Triangle, and Saw with a push of a button.

LFO 2 is a skewable LFO with three shapes. The LFO shape can be smoothly changed from a Ramp through Triangle to Saw wave shapes. The skew shape can be changed with the Skew knob or with CV

The Sample and Hold circuit's clock is normalled to the 2nd LFO but can be clocked externally as well. The sample and hold samples voltage from an internal white noise source and can also be replaced by an external voltage source. White noise has its own output as well for use with other modules and applications.

Both LFOs can be sync'd to an external clock source by holding the wave shape button for different lengths of time. As they are independent of each other, one can be sync'd while the other runs free like a gazelle on an African plain.

Tempo sync calculates the time between incoming clocks and reacts instantly to each new clock pulse. Each rate knob becomes a multiplier/divider when sync is engaged.
