Hi all.

If you love sampling, then you should find this very interesting. Everyone knows that sampling is an art in its self. It can be very difficult if not near impossible to loop evolving sounds, or even standard ones. So, any help in this area is obviously well worth talking about. That said; if you havent already heard of this program, let me introduce Seamless Looper by Zero-X.

Seamless Looper is a program that allows you to work efficiently with large numbers of samples of all shapes and sizes, quickly and easily. Even the most complicated waveforms can be looped in no time at all. So with that said, lets start by opening a few files and looking at what can be accomplished here. The files Im working with here in the first part are Trumpet sounds, so these would be considered standard files. Ill demonstrate the abilities of seamless looper to process near impossible evolving waveforms later on in this post.

So here goes.

Image 1

Im actually going to open every file in this folder at the same time in order to show you how the program organises everything. Notice how its all spaced out nicely, and no window is displayed on top of the other.

Image 2

Next I drag open the file I wish to see enlarged, and seamless looper scales the view perfectly. By simply looking at the wave file open in this way, I can roughly see where the waveform cycles, so lets also roughly select that area for processing.

Image 3

So I have my waveform, and the area where I think it might loop. Next all I have to do is press the S key. Doing this will bring up a window asking you what you would like set as the minimum loop size and what way seamless looper is to search. The following settings work without fail for me every time and I have never needed to change them based on the selections I make where I think the sample might loop.

Image 4

Now that Im ready to loop my sample, I hit the Auto Search button. At this point Seamless Looper will scan the selected area and report back all the possible points where the sample will loop.

I can hear all this loop points in real time by hitting the preview button and directly clicking on the values displayed. This is very handy because it allows you to quickly pick the best point possible.

Image 5

In this case with the sample Im working with, all the values displayed on the screen are actualy perfect loop points and the sample performs seamless. So, Im going to leave it on the very first choice, and so I hit the OK button which brings me back to the main screen.

I can now play back my sample and actually see where it was looped in the area I had selected. It sounds grea, a very smooth loop.

Image 6

All is left to do now is to crop away all the unused audio after the Loop End Point. This is done automatically by simply pressing the CTRL+E keys.

The end results will look like this.

Image 7

So thats how the process of looping a fairly standard samples goes. Its quick and easy. Next up is nothing short of a nightmare samples. This one fades in and constantly evolves in shape and size.

Image 8

The first steps that must betaken here to loop this type of sample is to deal with the problems of it evolving in size, and in true style Seamless Looper actually has the ability to level out the entire waveform automatically Smile

I start by pressing the V key. The settings Ive chosen have also never failed me, so I leave them as they are always.

Image 9

After processing the waveform now looks like this. As you can see, its nice and level, ready for looping.


When it comes to looping this type of sample, you need to take a different approach because it does not have any view viewable cycle to it, nor does it have one you can hear by ear. In all essence its technically un-loopable, so the selection you need to make here is more of a personal preference on what your hearing than any technical reasons. So, Im making this selection.

Image 11

Time to apply the first part of this loop. Pressing S as before brings up the scanning options, but this time around because this sample has no cycle to it, Im going to tell Seamless Looper not to show me any loop points under 1 second long.

Image 12

After activating the search, like before your presented with a list of suitable loop points. However, unlike before the ones presented will have a clearly defined point where the sample is jerked back to the start point each time it loops. This is expected, and is exactly what you are looking for. You simply need to listen to a selection of the points presented and pick one you prefer. None of them will be smooth, so its purely personal choice you need to make here. For this sample, Im going to chose the one with the points furthest away with each other.

Image 13

Ok, so the sample is looped. Now to remove the jerking effect and to smoothen out the loop point you simply press the X key to activate the Cross Fade features. This is by far the most impressive cross fade feature Ive ever seen. Its ability to smoothen out even the most poorly looped samples is truly amazing. So, for this sample Im going to use the following settings.

Image 14

After processing, not only does this give me a flawless loop in what Id consider an almost un-loopable sample, it does it effortless as you can see from the following image.

Image 15

It doesnt stop there either. You can even work in a multi track mode which is absolutely fantastic for processing samples for a multisample.

Image 16

Sound designers can also make use of the Formula Wave Shaping tools to create your own unique sounds.

Image 17

And to shape them.

Image 18

There are also a lot of other feature you can use to speed up your workflow. For example, you can setup Seamless Looper in such a way that by even opening a waveform for processing, its automatically normalised, or DC adjusted. Saves on repetitive tasks when working with large batches of samples.

Another very handy feature is the sample offset option. This feature allows you to make adjustments to the loop points upon saving the data, which in turn gives you full compatibility with all the different specifications surrounding the wave file format.

For example, if you looped a sample in something like sound forge, and imported it into your Triton. The start loop point would be imported incorrectly. It would be out by 1 sample. Most of the time this goes completely unnoticed as 1 sample location may not produce a pop or click. But, there are times when it will matter. This feature guarantees you 100% compatibility, and eliminates the need to double check data your importing. If it sounds right in Seamless Looper, it will sound identical to that on your Triton.

So thats some of what this program had to offer. Id highly recommend at least downing a demo and giving this ago yourself. Especially anyone new to sampling who has been disheartened by the looping process in other applications or on their KORG.


Kind Regards.

Is this still safe to purchase? The creators website is no longer available, so am slightly apprehensive. Thanks for any advice. Or an equivalent utility link would be appreciated. Laughing
