Re: Getting Started With Midi Sequencing
Your section Virtual Instruments vs Samples is inaccurate. A software sampler IS a VI. A better comparison could be made between samples vs synthesis where a sampler uses audio segments of real instruments, whereas a synthesizer mathematically models an instrument to replicate a sound. A synthesizer may use any number of different synthesis models - subtractive, additive, FM, physical modeling are just a few. What is important is the difference in demands on your computer and the accuracy of the result. A sampler requires more memory to allow the audio segments to play back on demand... the more memory you have, the larger sample collection you can use. A synthesizer works mathematically, so requires more processing power than memory. Generally, even the raw waves used in synthesis are not generated by samples.
As to accuracy of sound, generally sound types will be more suited to one type of generation than the other - acoustic pianos tend to sound better sampled, synth emulations tend to be better synthesized/modeled. This often comes down to the organic nature of the instrument being replicated. The more organic the original, the larger the sample required to emulate it. One of the things that is hard to do with samples is accurately crossfade changes. Take a hammond organ. If samples were used, it would be really hard to emulate the ramp up and ramp down of the leslie speaker. Since a real hammond organ uses tone wheels to generate its sound and these are pretty easy to replicate through physical modeling, a synthesized hammond actually sounds better than a sampled one. Samplers are becoming more and more complex, and the line between sampling and synthesis is being blurred. You could use for example, samples for the tone wheel generation, and synthesis to model the leslie speaker. This is of course just one example.
I know I tend to be harsh on typos and stuff (thanks for pointing out mine - KVM/KVR!), but you could probably do to read your article closely and fix a few words there... not just typos, but the wrong words.
