Whats more, the midi file created in such a way would be very non-standard, and would not work being played back on the general midi soundset. This is a highly skilled job though, requiring in depth knowledge of the instruments you are trying to emulate. They may use 6 different midi notes for the snare (say for a funk track) and expand the palette out to include different ghost notes etc, and can, with work, create something very convincing. Of course, you can set up your own midi drum tracks to include more sounds, and experts at creating midi based music for film scores or similar do just that. On a midi drum track you generally just get 'Standard Ride' and 'Bell', with a sample set that doesn't typically take into consideration what 'state' the cymbal was previously in when it is hit again (it just mutes the previous sample and plays the new one, this is not how it works in real life). Similarly there are many ways to play each cymbal, with drummers often taking many years to get their 'jazz ride' playing sounding good, attacking the cymbal in different ways, sometimes while it is already moving with different levels of energy to get it doing what they want. These details would probably not be picked up on the midi file recorded from the drummers inputs. Dead center for the backbeat, off to the side for ghost notes etc. But a drummer may be intentionally varying where they are playing on the snare skin all the time, to put in ghost notes and fill out the groove with many subtleties. For example a snare soundfont might have center snare, rimshot, maybe a sidestick, each at all the different velocities. Moving onto something like drums and you have a situation where drummers routinely use more sounds than are commonly included in a midi drum soundset. As a point of reference I've seen some super over the top piano sample libraries aimed at the professional MIDI worker to top out close to 500Gb, though in truth 50Gb is a bit more normal ) So for the MIDI file to sound suitably flawless you would need a soundset very close to what the original musician played it on.Īdditionally, there is just SO MUCH to model/sample on a piano that even the biggest and most expensive sample sets don't paint a complete picture, though some of them are very good. Playing music is after all an interaction with an instrument and a feedback loop, how you play is adjusted in real time depending on the sounds you hear coming back from the instrument so a midi file captured from an Upright acoustic piano (one of those models with a midi module of course!) is unlikely to CONVINCINGLY translate directly to a Steinway Grand, as the performances would be different. Sure it would sound 95% there if you switched sounds but you might have to go back and tweak it again. The resultant midi file would probably end up being fairly specific to THAT piano sample set, and may not work so well if you tried it using a different sound. Now it's possible, with a powerful computer, fast hard disks and an expensive piano sample library that you could get quite a lot closer, however this might take a fair bit of tweaking to get rid of any last little artefacts that sound artificial. However, bear this in mind, even if you have a fantastic piano player playing on the most expensive digital stage piano available then most experienced/professional musicians would still be able to detect that the 'keyboard instrument' was not a real piano. solo piano, and you got very very lucky with the sample set you paired to the midi. In theory, perhaps just about if it was a simple performance eg.
