Title: Creating samples with an unique feature?
Post by: FreezeFlame(Alchemy) on August 06, 2014, 13:45:42
Im curious on how to create samples that can be mixed and will produce an distortion effect upon mixing two seperate samples in the same pan even and playing them on two channels seperated (similiar to how those mixed synth sounds from the s3m module anyx work).

I included two samples i managed to create (within more then 3 hours of trial and error, and even then and now, im not sure i managed to create them to begin with :().
Play them together like this:

Wave1: Sample 01
Wave2: Sample 02

Still, gotta love there small size and sound ;).

This effect is pretty well-known as an easy method to fake pulse width modulation. It's actually enough if the second sample is identical to the first one, but inverted and with a slightly different base frequency. You don't have to create two completely different samples.

Then why is it badly documented then?

No wonder it worked (even if it was more an trial and error thing in the start :D).

Truly, what the heck can be done with sample modulation, is amazing.

Eh? Where would you document this? Certainly not in the OpenMPT documentation, because 1) it's not a trick specific to OpenMPT and 2) the manual was never intended to contain a list of tricks.
I'm pretty sure it's been covered in at least one tracking handbook, and you can probably ask pretty much any oldskool chiptune musician on the Amiga and they will tell you that they know this trick. It's so commonly used, why would anyone make a big fuss about it and document it as the next big thing?

So that others can to use it in there compositions without the need to find an Amiga chiptune composer and ask him about this case.

QuoteWhere would you document this?
On an wepside dedicated for making small sized module files without the need to go the chiptune road with describtion on how the tricks work and how they can be done (haven't saw one so far, and it can be a good resource for beginners).

Quote1) it's not a trick specific to OpenMPT
Know that. I can use this effect in anything that can process samples in 2 channels of the same pan even.
Quote2) the manual was never intended to contain a list of tricks.
Oh, alright.

Tracking handbooks exist?? Cool.

Well, there are plenty ways to find this out. The classic way to learn tracking is to look at what other people, anyway, and it's highly effective.

Go ahead. ;)

Yes, the classic Trackers Handbook (http://resources.openmpt.org/tracker_handbook/handbook.htm) is even linked on various places on this website.

Started reading it. So far its pretty neat :).

Its possible to do this trick without having an second slightly modified sample.
And its related to making an manual flanger (i call it faznik) effect by adding an fine portamento effect on an different channel.

Here's the code for IT:

And there's an topic in the Modarchive forum i found, which can be useful for small module projects and bad sounding samples ;).
