Q: BazTutorial15 granular synthesis

[disco judas]

Hi


In the last half of part 1 he is doing some stuff with connecting the end point of the sample and scaling amplitude. It goes over my head. Anyone please walk through it slowly?

I think you need to give us a link so we can see what you are talking about

Yeah, sure

Thanks!

Sorry, don't know anything about max/msp.

You could try this web site:
http://www.granularsynthesis.com/index.php

Or Miller Puckette's book 'Theory and Techniques of Electronic Music.' which has loads of theory which is then implemented in Pure Data examples:

http://crca.ucsd.edu/~msp/techniques.htm

This book is pretty comprehensive. (also free )

Perhaps if you amend the title of this thread to show it is a max question a max person may be able to help you more.

Thanks.


I feel like an idiot when looking at the maths of Miller Puckette book.
But, I want to learn it. Do you know this stuff.
Any tips for learning this stuff.

Cheers

I started reading the Millar Puckette book and doing the examples. I got into the second chapter and found it all a bit time consuming, you know, it stopped me actually doing any music. So I stopped because it was a bit low level. I bought Audiomulch which will do granular stuff but operates at a higher level.

Maybe I will try that sort of thing again when Max4Live comes out...

he is dividing the duration of the grain by 2 (to get half the duration) and with a line~ object using half the duration to fade in and half to fade out. if you look at the line~ help file you will see how you can send it four numbers. the first number is the number that it counts to, the second is the time it takes to count to that number... the help file explains all this in more detail with examples.

the tbf object orders the outputs. again if you recreate the object as it is in the video and go to the help file it is well explained. data flow, ordering input/output of information is one of the little but significant mathy learning curves in max. i think that if you have no programing background and are learning this on your own it will probably be a pain in the ass for a little while as your patches get more complex. but eventually you get it and you don't remember how you could ever not have gotten it. try to come up with some useless patches that just pass numbers which use the trigger object (and some other ordering objects, bucket...) than keep them for adding to patches which do something useful to you.

the scale object scales 2 sets numbers. so that incoming numbers from 1-100 could be expressed as outgoing numbers 1-10 for example. again better explained in the help files.

he is using this to scale between standard midi values 0-127 to his desired amplitude values min and max gain.

hope that helps a little.
