- Common MIDI Misconceptions #101 : Sample Dump Standard
-
- I have talked to (in person and here) many people who do not understand what
- "Sample Dump Standard" is. I have heard that it can get audio from a
- compact disk into your sampler, let you put a sample into a DX100, move a
- sample from any sampler to any other sampler.
-
- Like most misconceptions, some of these things are true. Sample Dump Standard
- is a specification by the IMA/MMA about the system exclusive passage of
- samples between MIDI devices, be they computers or other samplers. Like most
- standard (one size fits all) implementations, SDS is a loose standard.
-
- Many samplers in the world today do not support SDS. You can't move
- samples between SDS and non-SDS samplers. You need Sound Designer, Alchemy
- or SampleVision for that (blatant commercial plug.. hee hee).
-
- Some samplers that do support SDS do so in a non-standard way that renders
- them unable to communicate with other SDS devices. These include Pre-3.0
- Prophet 2000 series and Akai S900. These samplers live secluded in their
- little MIDI world, with only specially written computer programs to talk to
- them.
-
- In theory, SDS should make our (the software developer's) job easier, right?
- Wrong. In order to use the individual features on each sampler, we still
- have to write system exclusive routines. I have yet to hear of anyone
- who had an easy time moving samples between unlike samplers using SDS.
-
- As a means of conveying sample data between machines, SDS is, well.. less than
- optimum. An example is that SDS provides no way to just change loop points. If
- a computer program wants to set loop points in an SDS sampler, the computer
- must retransmit the entire sample over MIDI just to change these two values.
- You must always transmit the entire sample, even if you change just one
- sample. This can take minutes on larger samples.
-
- My main point here is to show that SDS will not save the world from non
- standard MIDI implementations. I think the attempt to standardize sampler
- transfer is a noble one, but impossible given the differing architectures
- of samplers from different manufacturers. We generally are able to support
- a sampler better when the manufacturer used their own system exclusive
- functions which better suit the sampler's architecture.
-
- Samplers that claim to be SDS standard:
- Emu EMAX, Sequential Prophet 2000/2002, Akai-Linn, Oberheim DPX-1,
- Forat F16, Dynacord ADD-1 & ADD-2, Yamaha TX16W.
-
- Samplers that do not use Sample Dump Standard:
- Ensoniq Mirage & EPS, All Rolands, Korg DSS1/DSM1, Akai X7000/S700/S900,
- Casio FZ1/FZ10.
