fmpsycho, if you keep going with these 'How to' threads, you'll soon have written a full user manual. Great work!!

:D

hehe ...

you Won;t live Long So is Exite 1 So... i am willing to give you a living Frog
Till Exite on will come out cause it ait ..\ to make you betifull noises

come on guys pitch in cause we all know that Exite one will Never Be out ...

3rd i have a Better idea ,, Lets make this the manual and help line and ,,, One day we all

Ok so i figure it out nuetron and all other wavetables around uses the waldorf oscilator and a switching machinism to get diffrent waveform the main thing is how to get a pc *.wav to load
cause the waldorf oscillator is a closed module so no way to actully understand but you can take a few of it's wav it's in the modules list and simple to manipulate well is there a way to load a wav Mark ?

There are some tools to create original wavetable ... on the original Waldorf MicroWave I (OS 2.0), MicroWave II and MicroWave XT !!!

The difficulty is more to understand how it works under scope: you have to combine the WaveTableOsc with a WT dsp file (one of the 64 available).
On the MicroWave OSC module for modular you can select the WaveTable Osc.
I do not know how to implement such thing with the SDK (to rebuild a Full MicroWave Osc module).
What would be more interesting would be to be able to create ones own WaveTable as with the original...
As soon as anyone find a trick, that would be kind to share with others !!! :D

Not quite sure what to say other than... you're barking up the wrong tree. :P

great - another one for my dictionary 8)

on topic:
does anyone here actually know how Wavetable Synthesis really works ?
I admit I don't - had a peek at the original Waldorf Docs once, obviously a too short one...
at least it's not about simply playing fragments of samples, as the adapted label by rompler manufacturers might suggest.

cheers, Tom

Hey that slang dictionary must be growing Tom. :cool:

I've attached a PDF we had here that talks about the general mechanics of WT synthesis. I suggest some research into the PPG which can easily be done here at PPG_dot_synth_dot_net

Ok, so here we go for Astroman.

Waldorf Wavetable oscillator principle:
=> you collect 64 single cycle waves and arrange them as a bank of material for your digital oscillator.
=> you arrange an index table of theese waves to set up a so called wave table
=> you allow to select which of these waves has to be used as a starting wave
=> then you allow to sweep through the table to change waves with the help of some modulators (enveloppe, lfos)
=> then you let the DSP interpolate between current wave and next wave in the table

If I get wrong somewhere, just correct me.

My 3 cents

thanks, that seems to nail it :D
and stardust seems to repeat my mistake
The key difference to samples is that wavetables are small snippets ... ;)
could one define (in alternate words)
the small snippets are a 1-dimensional array
the wavetable is another 1-dimensional array of indexes to the snippets
when (repeatingly) loading the oscillator single-cycle snippet interpolation is used

hey, that reads pretty smart, but a clear description nevertheless
cannot be that difficult, can it :D

cheers, Tom
ps: thanks for the PPG link, Mark

No worries. It's a great PPG site. Run by Paul Maddox that made the Monowave hardware synth (rare) & Monowave II chameleon synth, both of which were PPG WT based AFAIK. If you remove the PPG part of the URL you'll get to the home of synth.net where you'll find links to lots of other cool synth stuff. :wink:

if i got it right the way that digital osilators where created is Row of pre recorded PCM Wav Sines Looped and the difrrent between quasi and analog is that quasi preiodic is a Pcm wav form that is used for additive synthesis to generate other wav forms in that way Saving Space and Electrical power and other resorces.... ?

and then after making this addative digital oscillator the wavs in it generates the wavs as it's Functions ...

did i got this right ??

Ok , so you got me reading and i found diffrent ways to produce osillators and i want to say to you all that i found a lovley sienties that created an special clap osillator ...
his name was James k clapp and i want that last name cause it's cool ... to have that name ...

So i add a wikipedia links to you all if you want to know how to create your own sine wav and didn';t know how ......

Btw ... Great article ,,,,

you really changed the hole idea of this tread from how to make a Pcm sampler module that loads
wav and function as an oscillator that is not pre made
