Hi ! What's the advantage of DSsampler when compared to audiolayer ?
Maybe DS can stream from disk??

AudioLayer can stream from disk.
how?? is there a preference or something??
AudioLayer versus DecentSampler
1. AudioLayer supports EXS24 and SFZ formats
2. DecentSampler supports its own format
3. Both can do round robbin and have multiple layers
4. Both have some built-in effects, AudioLayer has more.
5. DecentSampler *.dspresets are essentially renamed xml files you can edit with a text editor that supports xml to visually see and verify your instrument is formatted correctly.
6. The documentation of what features/function are supported in DecentSampler instruments is well documented and you can verify what’s going on.
7. The support of EXS24 and SFZ formats in AudioLayer is now clear and well documented in the updated manual so you can make adjustments to sfz files.
8. In AudioLayer you can see exactly which samples are triggered.
9. In DecentSampler you can’t see which samples are triggered in standalone or AU.
10. There may be differences between how efficiently each of the apps run.
11. Trying to recreate the same sounding instrument in DecentSampler may be less straight forward than it seems.
12. The latest AudioLayer 1.4.0 and 1.3.0 on iPadOS 14.4.1 doesn’t import some SFZ files correctly whereas 1.3.0 on iOS 12.5.1 they load correctly. The updated manual documents what’s supported by AudioLayer is sfz so you can fix your instruments. DecentSampler files worked on both operating systems.
13. AudioLayer can use audio sample file names to automatically map them to MIDI notes when you create instruments using the app. The DecentSampler app can’t be used to create sample instruments it’s only a sample instrument player.
14. There’s a difference between the two apps in their initial price and what sample instruments they come with.
To a large degree when you want to use AudioLayer or DecentSampler may largely depend upon which instruments you want to use or create. Both apps have an abundance of quality instruments available.
Man that was some answer ! Many thanks
Pressing the handle on the "Toilet Lid Drone" is an experience. It sounds like the device you'd use on an alien space craft. Very useful for industrial textures.
Does DecentSampler also have automapping of samples to layers?
It would be interesting for someone to compare the efficiency. I am surprised by how many instances of AudioLayer I can run without problems -- and am able to use instruments whose sample sets are well over a 1GB without problem. I've been curious whether DecentSampler can do that.
AudioLayer wins this one... Decent Samples reports RAM consumption issues and halts so I don't think it does disk streaming. The Piano Book files are all well under 1GB in size and the larger ones often hold multiple presets.
With DecentSampler, you create an xml format file. Instruction on how to do so. There really isn’t any auto mapping of files, but you could create templates from other *.dspreset files by changing them to *.xml files and changing out the relevant note or file names. There is this Decent Sampler Helper Tool which uses JavaScript to automatically generate xml code from file names.
Here’s an interesting technique called the Monolith Sampling System for recording, processing, and creating sample instruments including those for DecentSampler I discovered on the pianobook site.
It would be very nice if the developer of SynthJacker added DecentSampler file export support as an option in addition to the sfz support it already has.
I guess I would say that the automapping is worth adding to the comparison list. As it works quite well in AL and doesn't require needing additional tools for importing sample sets that have conforming names.
More to the point, the DecentSampler app can’t be used to create sample instruments at all. Updated my original post to reflect these differences.
how?? is there a preference or something??
@Paulinko so AL is disk stremimg or not?
There is an option in DS for selecting auto, RAM or disk streaming, try it.
I have both, Used AL in my live set but I find it not very stable and CPU hungry, Had some bad glitches in the middle of some of my performances. Will try DS...
And... Another good diference, is the price!
13. Free vs $$$
Yes AudioLayer does disk streaming, they call it Stream Sample Engine details about it on page 4 of their manual.
Nice... i will check it out for stability. Hopefully I get fewer issues with max RAM triggering.
What hardware and OS are you running on? I’ve found AudioLayer to be robust and stable for playing. The only glitches I run into is occasionally when importing new instruments or when loading lots of instances at once on my iPad 6 (iOS 13.7) which is not a high RAM model.
Running a similar instrument (using the same sample set and MIDI source) on both apps in disk streaming mode on an iPad Air 3 running iPadOS 14.4.1, I found DecentSampler to be a little more efficient which makes sense as it has fewer built-in effects but the difference in efficiency was very small.
More significantly the two apps definitely sound different which may very well be due to my translation from one format to another. Below is a screenshot of the same four Klimpa samples from the pianobook site being used as an EXS24 in AudioLayer and in DecentSampler without any effects in either app being recorded on two separate tracks triggered by the same MIDI source. The DecentSampler track has some reverb whereas the AudioLayer track doesn’t. . . . very strange?!
In contrast using the slightly different samples for the EXS24 versus the original DecentSampler samples in the same basic preset format in DecentSampler yield virtually the same waveforms which is not surprising as they’re a fraction of a second different in length and the end portions of the sample are very low volume.
Finally we have the same four samples in AudioLayer using the EXS24 and SFZ instrument formats which are different from each other and the DecentSampler waveforms above.
It’s much easier to troubleshoot instrument creation using AudioLayer with its visual feedback on which samples are being triggered and to verify at a glance that your zones and layers are as you intended. Depending upon how complicated your instrument is, it’s not too difficult to convert an sfz file created for AudioLayer into an instrument for DecentSampler.
Dam that’s pretty detailed.
How did you create the .dslibrary? When you create a .dslibrary, are you able to use DecentSamplers bultin effects?
@Paa89 I’ll create a video of how I put together a *.dslibrary with a variety of *.dspresets using iPadOS apps, recording from analogue gear, and using DecentSampler’s built-in effects too.
I found a way to change the *.zip file extensions to *.dslibrary on an iPhone or iPad. Use the following "Shortcut":
https://www.icloud.com/shortcuts/fbc9a7d7777d42af8b7c94dd27983f7a
You will need to enable the use of "Untrusted Shortcuts" to use it.
Then you can download Decentsampler files and rename them so they will open Decent Sampler
and install the instrument. You will still need to use "File.../Load..." and click on the dslibrary file to
select the instrument.
If you have AudioShare, you can just use the rename functionality.
That works great. But it was also fun to finally use a ShortCut.
"Hey Siri, get me a beer."
I'll need a drone for that and a little beer heliport added to the fridge.
The file download ShortCut has been very useful for downloading files like Audulus from websites which are more complex file structures like *.dslibrary files.
@coniferprod - do you have the time and energy to consider this for a SynthJacker Update? There's
another free sampler app with a custom but well documented zipped files packaging. Just calling the
zip a *.dslibrary would help a lot of users since the file serving app calls them *.zip and the app won't
accept it so users need to change the extension which is not trivial on IOS.
(Your definition of trivial might vary with experience).
It’s trivial when you know how to change file extension names but clearly not well known nor obvious. Editing the code to transform a list of samples into the correct format can be very tedious and time consuming plus prone to errors so an IAP to do the conversion into a *.dspreset file would be well worth the money.
Can’t load anything. Any help?
