CDXtract provides the most reliable and powerful sampler utility for the audio professionnals.
CDXtract is based on a very sophisticated and robust architecture that is fully object-oriented. Most of the high level functions required to work on sampler files are directly implemented in the Kernel and accessible to any format that needs to use it. The advantage of this architecture is that the same code is not duplicated again and again, moreover it increases the overal reliability. One example is the support of alternate loops that are available in some hardware samplers but not in any software samplers so far. Each sample read by CDXtract is handled by a special object called a "Virtual Sample", this Virtual Sample is responsible for providing audio data to any other components. If this sample has an alternate loop then the Virtual sample object will emulate its looping mode and will provide audio data accordingly which means that the player and all the converters don't have to deal with this alternate loop problem, for them it's just a simple forward loop. This guarantee that an alternate loop will always be perfectly converted whatever the destination format is.
Here again CDXtract benefits from a excellent design based on a driver technology. Each source format and each destination format are implemented as drivers and all the conversions are performed through an internal format. So everytime we add a new destination format then all the existing source formats can be converted to this new destination format, and everytime we add a new source format then it can be converted to all the existing destination formats. That's why the number of possible conversions in CDXtract is growing at an exponential rate, while the competition is still adding one conversion at a time.
CDXtract has always been a precursor and again this version 4 includes some unique features that bring the sampler conversion to a new level of creativity. CDXtract 4 allows you to select several programs and combine them in different ways. For example you can stack them on top of each other in order to create new multi-layered programs. Possible applications are infinite, you can for example create a new violin instrument by stacking a legato violin, a staccato violin, a tremolo violin and finally a pizzicato.
CDXtract 4 includes a stack editor that allows you to adjust the velocity scale and the global velocity response of your new multi-layered instruments.
Given the number of possible conversions within CDXtract, the number of options available is quite large. Moreover it's not easy for the user to understand if a given option affects or not one specific conversion. That's why CDXtract 4 has an extremely intuitive representation of all the options applicable to each conversion. All the options are represented in a conversion graph that speaks for itself. In the following example, we are converting an Akai disc to the EXS24 format. The Akai programs with the same program number are automatically merged with the "AutoMerge" option, then the tuning reference is adjusted from 442 Hz to 440 Hz and the output level is set to -6dB. The Akai stereo samples are converted to stereo interleaved samples and they are saved in the same folder using the Aiff format.
