Batch xFader is designed to accomplish the tedious work involved making sampler instruments out of samples. This process generally involves
Batch xFader can accomplish all of these tasks as a batch process on the selected folder of WAVs very quickly. It supports x64 Windows and is a Mac Universal Binary & so natively supports both Silicon and Intel Macs.
The embedded sustain loop is a region that plays until the sound is released/faded out and it’s essential for making sure that held notes still play after the audio data has finished. If you use MPC/Beats to suto sample, this loop region can be embedded automatically. Batch xFader can either use this loop or replace it with a new one based on percentages.
This loop section will sound unnatural & glitchy when it loops without some kind of processing. Some samplers do offer real-time cross fading to solve this problem, but if this is done permanently to the file it means the sample will always work with every sampler. Batch xFader uses an equal power method of cross fading which sounds very natural without the volume drops of Linear cross fading.
Cross fades use data from before the loop section starts and fades it in at the back end of the loop to achieve the natural loop, so it’s important to have enough audio before the loop for this. The cross fade amount is set using the slider & the graphical display shows this area and the fade section in red.
Generally when recording on computers there is some sound card latency which introduces a small delay at the start of the files. You can use a sample editor to find out the size of this in samples and use this box to enter that number. Batch xFader will then trim that amount of samples from the start of each sample. You may not need the front section at all after the loop is calculated and so selecting ‘ALL’ will trim the entire front section excluding any fade in time.
When a sample doesn’t start on a zero crossing it produces a click. Whilst it’s possible to use an envelope attack in a sampler to hide this, this option allows creating a short fade in to permanently avoid any clicks. This value is in samples and usually 100-1000 is enough.
Usually the data after the sustain loop isn’t required as the sustain loop plays until fade (unless there is a specific release loop in the sample), and so this option allows deleting all data after the loop.
If for example you have recorded a mono instrument using MPC/Beats auto sampler, it always records in stereo. This option allows taking the 1st channel only and converting it to mono. This option is carried out before any other processing so it saves time too.
In the Process section you select the Source Folder which contains the samples you wish to process. Note that Batch xFader does not write over your original samples, all samples are saved within the ‘EXPORT NAME’ sub folder which will be created if it does not exist.
As well as the ability to export at the original Bit Depth/Samplerate, there is also the ability to export additional formats in case you want to support specific samplers that only use this samplerate etc… For example Elektron devices use 48khz, whilst MPCs use 44.1k.
When ready, click process and all files will be processed using the settings.
