The Sound Structure of the A3000

The sound structure of the A3000 introduces an innovative concept of organizing Samples and
Programs. This departs from the more or less hierarchical sound organization of
conventional synthesizers / samplers, as shown in the following three examples:
Fig. 1 = Hierarchical Sound Structures
Example 1 Example 2 Example 3
Multi Performance Program
Voice Patch Keygroups
Waveform Partial Zones
Sample Sample Samples
In all these examples there are four levels that are based upon each other.
In comparison, the sound structure of the A3000 looks (and is) very simple:

Sample - Sample Bank
Obviously there are only two levels, in which SAMPLES and SAMPLE BANKS are
organized on the same level. Single samples can therefore be assigned to the Program
directly, without having to be organized in a Sample Bank.
However, if one sound consists of several samples that are spread over the keyboard (i.e. a
"Multisample"), these can be combined into a Sample Bank and managed as a whole.
Another feature of the sound structure of the A3000: In addition to the actual sample data,
the SAMPLE itself can contain all sound parameters, which in other schemes of sound
structure can only be applied at higher levels. Thus, we need to distinguish between the
WAVEFORM DATA and the SAMPLE PARAMETERS.
On the other hand, not all sample parameters have to be set within the Sample.
Parameters such as Level, Pan, Filter, Envelopes, LFO, MIDI-Ch. etc. may be set globally
for all samples of a SAMPLE BANK. The individual parameters of the single samples then
remain unchanged. The advantage here is that the Samples can be freely assigned to other
Programs without affecting the sample's sound parameters.
The "Performance Level" of the A3000 is the PROGRAM, which can be compared to the
Multi Programs or Performances of other synthesizers and samplers.
Programs allow the creation of complex Multi Setups, or alternatively, Performances with
layered or split sounds – or simply "Voices" with one sound based on one Sample or Sample
Bank.
