TUTORIAL: 'Single wavecycle' resampling

[Project_B]

This made my evening. excelent. Care to show some examples of this technique in action?

[futures_untold]

Maybe later, but I've other tutorials to write before I make audio examples tbh...

You could post up a few though.

Nice one futures!

Been on the single cycles for a while now, I just love resampling so much

This and then layering single cycles gets some pretty awesome sounds especially when you start modulating stuff too. I was thinking of doing a little tutorial on something like this at some point but I think you've covered everything.

Also another nice thing to try; layer up a few different resampled waveforms and then modulate the volume of each individual waveform for that smooooth morphing effect, sounds good man

iv got a folder of about 300 korg waveforms somewhere if anybody wants i can upload it. i heard the other day that looping an 808 kick in the right place can make for an amazing sub.

tbh loading any home made sample into kontakt & fucking with the loop points gives better results than the korg pack tbh.

Good stuff. Loads of wavetable synths around - Korg wavestation of course, Surge does it, etc etc. Top fun, so it is

wouldn't mind an upload, big ups.

Ableton Live's Sampler Actually works amazingly well for this. You can load up to 128 samples and chain them so that a midi controller (or mouse) can scroll through every sample. Sampler also has a built in filter, oscillator, amp envelope, two LFOs that can be used to modulate anything, and makes it extremely simple to isolate a waveform.

Actually that was helpful, thanks for the insight.

El-B covers it well in this video here:

I'm surprised people do it so little. I mostly make breakcore, so snare rushes are present in pretty much every tune, which inspired me to sample a single wavecycle even before I learned how to do 'proper' sound design.

I often use a 909 kick, turn it into a layered gabber kick with all sorts of effects and processing on it (I process my hardcore kick drums the way most people process Reeses) and then sample a bit over a single cycle (for extra dirt) from the release portion of the kick.

Makes for reaally fucking dirty ass basslines.

this needs to be bumped!
my question: how can you make actual wavetables? i'd love to experiment with that one day (though i suppose it's a really really boring task). in my imaginary world of simplicity there would be a way to select a single wavecycle in a sample and then just scroll the marked area sideways to get a number of snapshot-wavecycles, enabling you to smoothly morph from point A to point B.
is there something like this? and even if there isn't, and i could be arsed to spend a day cutting out single wavecycles, how do i transform them into a wavetable file to load into my synth?

by the way: you should be awarded, futures_untold. your threads have helped me so much!

I had a go at something similar to this. Grabbed a bunch of single cycle wave samples that i found online and pasted them end to end to make a huge sample with a bunch of different wave forms. Threw it in a sampler and set the start and loop offset points to move via the mod wheel. Not exactly what i was after but it sounded pretty cool.

[futures_untold]

The oldskool method is to cut and paste each wavecycle period as you both describe above.

There are two alternative methods.

The first is to find/write a program that generate wavetables mathmatically.

the second is to find a program that 'fills in the gaps' between the start and end waveshape, thus giving a wavetable. One such program exists, yet is a module for Synthedit. It can be found at http://evm.110mb.com/modules/wavetableeditor.htm

Something which may prove useful is the Blofeld Wavetable generator found at http://lady.rdsor.ro/~kotro/index.php?m=soft

A similar program is http://www.kvraudio.com/get/1731.html, although this only generates individual wavecycles.

the architecture waveforms kick as!

Posting in this thread so I can come back to it later, will help me with my basslines.

Zebrallete has the ability to draw your own waveforms, load waveforms and morph between wave snapshots.
Plus it`s free.
Very powerful freeware.

How accurate is audacity at cutting on the zero crossing?

Also, another question.. When you set up the loop settings of the waveform in a sampler like abletons sampler, do you set the loop to play forward then forward again when it ends its cycle, or forward then reverse? i can only seem to get a decent result when it loops from the start point to the end, then loops back round from the start.... I would of thought that it would of made any diffrence, since slicing at the zero crossings should mean a seamless loop, but when I loop a single cycle of say a sine wave, I get wierd results looping the sample "forward - reverse"


hope that makes sence


also, is anyone doing this in Kontakt, if so how have you set the loop up.

[VirtualMark]

its easy in kontakt. firstly i put it in sampler mode instead of dfd, then i can hear the wave as i adjust the loop points. set the loop up to go from start to finish over and over.

it doesn't need to be zero crossing - think of a saw wave. it goes from minimum to maximum over a period of time, then instantly drops to minimum again. the best thing to do is just load up a sample and experiment with different loops, its pretty easy once you get used to it.
