A Few Minutes with BEAP, Part 2

In Part 2 of the "A Few Minutes with BEAP" tutorial series, we look at three example oscillators that can provide a lot of interesting sounds to your patch. We look deeper into the OSCILLATOR module - the core of Part 1. Then we look into the FM oscillator - along with a resource on using FM synthesis. Finally we take a look at the SAMPLR module, which gives us sample access within our patch - as well as the ability to sample our own work.

Swapping out oscillators in a great way to find some interesting sounds without having to make massive patch changes. This video should inspire you to take you BEAP patching to the next level!

All the tutorials in this series:Part 1, Part 2, Part 3, Part 4, Part 5, Part 6, Part 7, Part 8, Part 9, Part 10, Part 11, Part 12, and Part 13.

Hi Darwin, I'm just getting into BEAP. I've started reading the Simon Cann book you recommended.."how to make a noise", but i'm stumped. He writes little exercises about the FM8 but I don't know what the simplest correct arrangement is in BEAP to create the Carrier and Modulator patch. (Also C:M ratios..i have something but i don't know if it what he means.) Since you refer to this book could you attach simple patches that refer to what simon is talking about. Your tutorials are great, i'm just getting lost in what is fundamental to FM synthesis and what is fancy.

Is this attached patch the most basic FM setup that Simon refers to in his book chapter 1 Figure 1.2 ?

One of the easiest ways to experiment with the C:M ratio is to use the "FM Oscillator", which has a control for the Ratio (which is, in fact, the C:M ratio). Here's an example patch that shows a comparison of the two alternatives:

Copy patch and select New From Clipboard in Max.

But if you want to use standard oscillators, it is probably easiest to switch out of "SEMI" mode into "FREQ" mode (the button for tuning...), then the numbers represent the frequency, which is something that will be easier to work with using Cann's book.

My patch shows classic C:M arrangement with two oscillators, then (like yours) the use of an FM oscillator. You'll find that they work differently - mainly because of the oscillators that are used to create the C:M combo. The FM oscillator will actually work better as an adjunct to the book.

Hi Darwin,
Your tutorials are great, i love it.
And I have another Question to you.
Is there a way to get the source code of the BEAP module?
@Enki:
There is another Book in German.

the source code is contained in the module. select the module, find the Object menu up top, select Open Object, and then click the toggle presentation view button
