Waldorf Wave Table
Wavetable synthesis is a technique that employs arbitrary in the production of. The technique was developed by of (PPG) in the late 1970s and published in 1979, and has since been used as the primary synthesis method in synthesizers built by PPG and and as an auxiliary synthesis method by and. It is currently used in software-based synthesizers for PCs and tablets, including apps offered by PPG and Waldorf, among others. It was also in a similar time frame by Michael McNabb, who used it in his 1978 composition. Contents. Principle Wavetable synthesis is fundamentally based on reproduction of an arbitrary, single-cycle. In wavetable synthesis, some method is employed to vary or the selected waveform in the wavetable.
The position in the wavetable selects the single cycle waveform. Digital between adjacent waveforms allows for dynamic and smooth changes of the timbre of the tone produced. Sweeping the wavetable in either direction can be controlled in a number of ways, for example, by use of an LFO, envelope, pressure or velocity. Many wavetables used in PPG and Ensoniq synthesizers can simulate the methods used by, such as Pulse Width Modulation by utilising a number of of different. In this way, when the wavetable is swept, the duty cycle of the pulse wave will appear to change over time. As the early Ensoniq wavetable synthesizers had non resonant filters (the PPG Wave synthesizers used analogue Curtis resonant filters), some wavetables contained highly resonant waveforms to overcome this limitation of the filters.

Confusion with sample-based synthesis (S&S) and Digital Wave Synthesis In 1992, with the introduction of the the term 'wavetable' started to be (incorrectly) applied as a marketing term to their sound card. However, these sound cards did not employ any form of wavetable synthesis, but rather samples and. S&S (Sample and Synthesis) and Digital Wave Synthesis was the main method of sound synthesis utilised by digital synthesizers starting in the mid 80's with synthesizers such as Sequential Circuits Prophet VS, Korg DW6000/8000 (DW standing for Digital Wave), Roland D50 and Korg M1 through to current synthesizers. User wavetables The creation of new wavetables was previously a difficult process unless supported by specialized editing facilities and (near) real-time playback of edited wavetables on the synthesizer. Such editors often required the use of extra hardware devices like the Waveterm or were only present in expensive models like the WAVE. More commonly, pre-computed wavetables could be added via memory cards or sent to the synthesizer via MIDI. Today, wavetables can be created more easily by software and auditioned directly on a computer.
Since all waveforms used in wavetable synthesis are periodic, the and representation are exact equivalents of each other and both can be used simultaneously to define waveforms and wavetables. Practical use During playback, the sound produced can be harmonically changed by moving to another point in the wavetable, usually under the control of an or but frequently by any number of modulators (matrix modulation).
Doing this modifies the harmonic content of the output wave in real time, producing sounds that can imitate acoustic instruments or be totally abstract, which is where this method of sound creation excels. The technique is especially useful for evolving, where the sound changes slowly over time. It is often necessary to 'audition' each position in a wavetable and to scan through it, forwards and backwards, in order to make good use of it, though selecting random wavetables, start positions, end positions and directions of scan can also produce satisfyingly musical results. It is worth noting that most wavetable synthesizers also employ other synthesis methods to further shape the output waveform, such as (filters), and. An example of, where the data at addresses from 63 to 67 are zoomed. (based on Figure 2.1 on ) On, it is called f-table (function table), and used for various purposes including: wavetable-lookup synthesis, note mapping, and storing ordered.
Table-lookup synthesis (or Wavetable-lookup synthesis ) is a class of methods using the tables by, called 'table-lookup oscillator' technique. The length of waveforms or samples may be varied by each sound synthesis method, from a single-cycle up to several minutes. Terminologies The term ' waveform table' (or ' wave shape table' as equivalent) is often abbreviated to 'wavetable', and its derive term ' wavetable oscillator' seems to be almost same as ' table-lookup oscillator' mentioned above, although the word 'wave' (or 'waveform', 'wave shape') may possibly imply a nuance of single-cycle waveform. However, a derive term ' wavetable synthesis' seems slightly confusing. In a natural usage of words, its original meaning is basically same as ' table-lookup synthesis', and possibly several actions on waveform(s) may be expected, as seen on a paper about (a simplest class of ' wavetable-modification algorithm' known as ). Then in the late-1970s, Michael McNabb and independently develop the multiple-wavetable extension on the table-lookup synthesis which was typically used on and known with wavetable sweeping, and it was later referred as ' multiple wavetable synthesis'. Simultaneously since late-1970s, also the using relatively long samples instead of single-cycle waveforms, have become influential by the introductions of the and.
Background On the above four terminologies for the classes of sound synthesis methods, i.e.,. Wavetable synthesis — original, generic meaning (i.e. A single-cycle table-lookup synthesis). Multiple wavetable synthesis — developed by McNabb and Palm, typically used on. Wavetable-modification algorithm — including. if these had been appropriately used to distinguish each other, any confusions could be avoided, but it seems failed historically. At latest in the 1990s, several influential products were marketed under the similar to 'wavetable synthesis' (including wavetable card, wavetable, and ), and these confusions have further affected on the several industry standards (including algorithmic and wavetable synthesis, and optional hw acceleration wavetable synth ).
As a rebound of these, at the latest since the mid-2000s, a new confusion seem to begin flourish. Merely a subclass of generic wavetable synthesis, i.e. McNabb and Palm's multiple wavetable synthesis, tends to be erroneously referred as if it was a generic class of whole wavetable synthesis family, exclusively. As a background of these confusions, the difficulties of maintaining the consistencies between concepts and terminologies during the rapid developments of technology, may be significant. And it is a reason why this slightly classical terminology 'Table-lookup synthesis' is explained on here.

SOS contributor Steve Howell replies: Wavetable synthesis is actually quite easy to understand. In the early days of synthesis, (analogue) oscillators provided a limited range of waveforms, such as sine, triangle, sawtooth and square/pulse, normally selected from a rotary switch.
This gave the user a surprisingly wide range of basic sounds to play with, especially when different waveforms were combined in various ways.; Strong, Alex (1983).

The wavetable-synthesis technique is very simple but rather dull musically, since it produces purely periodic tones.

Multiple wavetable synthesis, the subject of this paper, is based on a sum of fixed waveforms or periodic basis functions with time-varying weights. Scheirer, Eric D.

The original specification was contributed by E-Mu Systems and was based on their “SoundFont” format 15. After integration of this component in the MPEG-4 reference software was complete, the MIDI Manufacturers Association (MMA) approached MPEG requesting that MPEG-4 SASBF be compatible with their “Downloaded Sounds” format 13.
