It's not that either is always better or worse, though, they are just different and tend to be good at different things. Some instruments are synthesizers in the traditional sense (generating their sounds electronically/algorithmically), some play manipulated samples. I wonder whether some are just synthesized, with no samples at all? But all else equal, a mono instrument will require half the sample space of a stereo one. This doesn't make these things synthetic sounding. Even the Rhodes and Wurli EPs are mono (though they are often played through stereo effects). there's no such thing as a stereo flute, trumpet, or violin, so you'd expect all those sounds to be mono. Many samples are not stereo, that's true, and in fact most "real world" instruments are not stereo, i.e. Pedaling? You mean sustain pedal? That doesn't require samples, except perhaps for piano resonances (and the pedal noise itself) on some models, and also, it doesn't apply to instruments other than pianos. Pipe organ and harpsichord, probably not (because their timbres don't really vary with velocity/volume). EPs (Rhodes, Wurli, etc.) are almost always going to have velocity layers. There are all different kinds of secondary sounds, with different parameters, and can also be done differently on different keyboards. They lack all of the long-sample nuances. Rumor has it that most of those other secondary sounds have tiny samples. Short version: The amount of total ROM in a keyboard, by itself, tells you very little about the size of the piano sample set. your Avant Grand example with four 1GB ROMs could hold more than 4GB of audio data). And just like acoustic piano sounds, the amount of space these sounds take up can vary a lot, as can the number of such sounds a keyboard includes.Īlso, compression can be used, such that a certain amount of physical ROM can actually hold more data than its spec implies (i.e. So if there are other sounds (EPs, strings, whatever), they will take up ROM sample space as well. As is how many velocities a note is sampled at.īut also, very few (if any?) keyboards have nothing but a single piano sound in them. Also how many actual notes are sampled (as opposed to being stretched from samples of nearby notes) is a big factor. In terms of how much ROM (or other storage mechanism) is required for piano samples, longer periods before looping may be more of a factor than the length of the loop itself. I suspect that most other sampled pianos lie somewhere in between.
CANDYBAR KEYBOARD CASIO MANUAL
I managed to find the service manual online today, and those sizes are clearly marked as GB, not Gb. In contrast, the Avand Grand N3 has four 1 GB ROMs. They're probably included in the higher-end CLP270/CLP280 models. The schematic shows two more slots for ROMs, marked "not installed". The lack of clarity makes it hard to know just how big the samples are.
CANDYBAR KEYBOARD CASIO PLUS
Plus one more flash ROM of unspecified size. They're labelled as Program/Wave, presumably shared for programs and samples.
The service manual for my old CLP240 (released by Yamaha in 2005) indicates two 128 M ROMs. Loop length is partly (largely?) dependent on the size of the samples in ROM, so I thought it might be instructive to find out how much sample ROM exists in modern pianos. long after Dewster's extensive test coverage of that subject some years ago. In another recent thread the subject of sample looping has resurfaced.
