Yes. The instruments comply with the limitations of the original sound chip in regard to the following: the waveforms used for the creation of the samples the number of voices (limited to either one or two voices, depending on how the instrument would typically be used within a composition) the 15 available levels of volume the precise pitch frequencies the speed at which the sound within a sample can change over time (e.g. in arpeggios, samples that change pitch or pitch bend, the timing of volume changes, etc.) There are a few minor exceptions, such as possibly overlapping voices when using the drum kit products due to how sample drum kits have to function with the respective software samplers. And of course, the instruments can be used in any way you want! This is only to say that everything is compatible with genuine 8-bit music composition, but there are absolutely no restrictions on how you use the sounds!
