- I understood what you meant, but the two methods ARE equivalent in that they
- both reduce the amount of sample data which has to be stored in the module.
-
- Premixing does have its own problems, though - overlaying several samples
- played at different speeds can produce unpleasant artifacts when looping,
- unless the loop points are chosen carefully. Premixing also requires more
- memory when playing the modules, and could produce an appreciable delay
- before playing if many different sequences are to be mixed.
-
- If the samples are mixed in real time (effectively using up more channels, of
- course) none of these are major problems; you run into CPU/DMA load problems
- instead, depending on the available hardware.
-
- Clearly, a system that implements both - preprocessing AND many channels -
- would be the most flexible solution.
