A wikipedia wavetable explantion:

To begin the process, the sound of an existing instrument (a single note) is sampled and

processed using a spectrum analyzer, producing a graph of overtones contained in the

sample. This graph is then parsed into a sequence of samples or wavetables, each having

one period or cycle per table, generated by adding together the partials at each parse point. A

set of wavetables with user specified harmonic content can also be generated

mathematically. These wavetables are typically arranged one after the other in a random-

access memory, allowing for easy access and nearly instant start-point changes; when the

data is played back, a phase accumulator looping at a set rate (determined by the sample

rate and the frequency of the note desired) feeds the samples to a digital-to-analog converter,

creating a continuous waveform at the given frequency.

During playback, the waveform produced can be changed by switching to a different starting

point in memory, usually on command from an envelope generator or low frequency

oscillator. Doing this modifies the spectral characteristics of the output wave in real time,

producing sounds that can imitate certain analog instruments (such as organs, pianos,

harpsichords and reed instruments) acceptably without requiring the use of a pulse code

modulation technique, which requires much more memory and higher sample rates for good

results. The technique is also useful for evolving pads, where the waveform changes slowly

over time and can reverse itself or loop back to an arbitrary point.

Since a wavetable oscillator can generate arbitrary waveforms, it is also possible to load

simple sine wave, square wave and sawtooth wave tables and use the synthesizer like an

analog synthesizer, using subtractive synthesis to modify the sound. Also, some wavetable

synthesizers (such as the PPG Wave 2.3 with Waveterm) can reset the loop point on the

phase accumulator to a period longer than a single cycle, making a PCM mode possible with

minimal hardware changes.

Just a quick tip for windows users, you can use waveosaur to do some single cycle

waveforms, its freeware and actually pretty cool - http://www.wavosaur.com/

To find single cycle waveforms from classic analogues go here:

Yes, the double draw machine will allow you to mix waveforms. You don't have to mix them

thought. There is a mixer so you can set how much you do or don't want your wave mixing.

There is a Time parameter allowing to determine how quickly the two are interpolated (mixed

over time). Width sets the pitch difference between the two. It's a very cool machine. Loads of

sonic possibilities. Plus, you can then use the LFO's to even get freaky with it.

While the Digi Ensemble only has one loadable waveform, it does have the PCH2, PCH3 and

PCH4 + the Chorus which gives you poly like character and enormously big pads and that

whole mess.

Wave machine ‘time’ parameter:

Turn up the intensity of an LFO which is controlling osc waveform then mess about with the

time setting to hear the effects, off is steppy and going clockwise smooths things out.
