CheeseTracker ~ Sampler & Sequencer


CheeseTracker is a software sampler and step-based sequencer. It allows a musician to turn single-note samples into instruments capable of covering three or four octaves (by playing the samples at different speeds, resulting in different pitches). In addition, it is possible to take a collection of samples that are recorded at different octaves, and combine them into a single “instrument,” allowing for even more octaves without sampling artifacts.

Using the Pattern Editor, it is possible to compose songs with these instruments that the computer plays automatically. The Pattern Editor allows the user to arrange samples in several independant channels, so that many samples can play simultaneously. These songs, and the samples which comprise their instruments, can be saved together in one-file archives called modules.

CheeseTracker imposes no limits on the length of the samples used. As a result, it can be used as a mixer as well as a sampler/sequencer. Effects such as reverb can be applied to each sample individually, eliminating the need for expensive pedals.
