With our new round of courses starting up tomorrow, it seemed appropriate to do another video tutorial with Maths, the Make Noise favorite that is the basis for one of our classes. This time, we’ve employed the module to perform a function that isn’t usually associated with Maths at all, that of a pseudo-Complex Oscillator.
Of course, Maths has many functions that make it useful for virtually any patch. Its most common uses are as an Envelope Generator and LFO, though it can perform dozens of other tasks. However, as you may know, an LFO is just a audible oscillator cycling at a slow rate. So if we increase the cycling speed of the LFO, it becomes a basic oscillator.
Maths generates triangle waves based on the comparative shape of the Rise and Fall times. That triangle wave can be bent closer to a saw or ramp wave, by changing the Rise and Fall values. Channels 1 and 4 can both produce these wave shapes, and can be patched to control each other without patching externally (a patching convention dubbed “inbreeding”).
While this is only one example of how we can inbreed Maths, it is a fairly powerful one. If the Unity output on Channel 1 or 4 is routed to the Both input on the other Channel, the result is one Channel Frequency Modulating the other Channel. This can yield interesting atonal results, as the module does not have a dedicated 1 Volt per Octave input. If instead we use the SUM output to control the Both input on one of the channels, we can get even more complex and varied tonalities.
Maths isn’t going to replace your other Oscillators. However, using it in unexpected ways can expand the way you look at your system, hopefully opening your mind to other avenues of exploration.
