In the last article, we did a lot of setup - we got input/output handling in place, and added a compressor to the processing chain as an example of an “effect module”. In this article, we will continue adding effects, including a dual overdrive module and a three-stage EQ/Filter module. With these additions we will further explore Max 5’s user interface options, as well as taking a look at some of the “tweaks” that make Max/MSP functions a little more guitar-faithful.
Last time out, we created the LFOur, a generative patch composed of a quartet of synchronized LFOs whose output we can use to make noise. While it's interesting to watch how the different LFO configurations make combinatoric waveforms and it's restful and instructive to watch the sliders flick and rock, it would be nice to have something to connect it to. This tutorial includes some patches that will do just that.
In an earlier article, Andrew Benson and Ben Bracken went through the process of connecting a guitar to a Max-based processing system, and creating a few guitar-oriented effects patches. In this series of articles, I will be building a Max-based guitar processing "rig", and will give you the opportunity to look over my shoulder as I design and implement this system.
I'm personally a lot more interested in the ability to synchronize processes in Max using time values that resemble musical note values to create control structures that can be easily time synced. This tutorial is about making one of those kinds of modules - a quartet of synchronized LFOs whose outputs I can sample individually for several kinds of data (triggers for waveform start, LFO outputs that I can sample at variably synchronized rates, and a nifty summed waveform I can use for more exotic kinds of control).
