Two 9 stop evaluation sample sets are available for free download. The first comprises the single-channel samples (ie a blend of Close and Ambient) whilst the second set incorporates all three perspectives - Close, Ambient and Surround. These sample sets are fully functioning without time-out or limited compass ranks and are provided on a freeware basis. Please see below for the full licensing terms.


The memory requirement at Hauptwerk default loading conditions (16 bit, lossless compression, all loops and releases) is approximately 1,645 MB for the single-channel set and approximately 4,768 MB for the multi-channel set. The single-channel evaluation sample set is compatible with Hauptwerk Free edition, but only if the set is loaded at 16 bit with lossless compression and - crucially - the multiple sample loops drop-down box is set to “Load only first”. Loading in this fashion takes 1,433 MB memory.


Although the sample set is small, the samples (24 bit, 48 kHz) are identical to those found in the larger sets which, along with the array of couplers, pistons and other playing aids, should allow ample opportunity for evaluation. Separate samples for all tremulant affected stops are also included, along with the ability to control the volumes of all divisions and - for the multi-channel set - the volume of the Close, Ambient and Surround perspectives.


Incidentally, with reference to the main user manual, please note in particular the section on Temperament and Tuning and the recommendation to set the Random Pipe Detuning Adjustment in Organ Settings | Organ Preferences to zero when using any temperament other than the original organ tuning.
