LP Waveform morphing!!

Jiggz · Post by **Jiggz** » Sat Sep 02, 2006 11:34 am

From the manual:

"Because the waveform is voltage controlled, this parameter can be modulated. This allows the generation of some very interesting timbral changes."

Now i really want a LP......additive synthesis!!

I dont know much about the Voyager, but can it do this? This really does make the LP capable of some uniqe sounds that push it further than your average subtractive (at least the ones i've played).

I would love to hear this in action. (continues to drool)

yep, the voyager can do that. The fact that you can modulate the waveforms in a number of waves AND the fact you have continuously variable waveshapes makes for endless variations in sound!

Not many synths offer this.

I wish you could modulate the individual wave forms via the mod busses. The way Voyager is set up now, you can only modulate all of them together.

really? im sure you can send mod from mod bus 1 to osc1 wave and same with mod bus 2 to osc 2 wave or am i missing something? And if you use pot mapping and a foot pedal that gives even more options.......

You can't via the mod busses. Only all three waveforms together.

Jiggz,

Waveform modulation isn't the same thing as additive synthesis - those are entirely two different concepts.

Waveform modulation will give impart an interesting animation without altering the basic sound (think of what a chorus pedal does and you'll get the idea). Both the Voyager and the LP offer waveform modulation, but the Voyager offers more possibilities because it has more control options. Since the Voyager and LP waveform parameters are voltage controlled, you have more sonic options than the simple pulse-width modulation (PWM) available on your average subtractive synth.

Gold,

You are correct - it is possible to modulate a single Voyager waveform. Pierre Zeeman offered this as one of the many cool techniques in the 'Tips & Tricks' document posted on SquareWave this month.

Yeah, i know..... it's poor man's additive synthesis. I think you would need a wall sized modular to even attempt additive synthesis.....and i emphasize the word attempt heavily!

But in essence real additive synthesis is still shaping the waveform by adding or subtracting harmonics at varying intervals no? (correct me if i'm wrong), so in this sense the waveform modulation on the Voyager and LP will achieve interesting timbral changes that are reminiscent of additive synthesis, especially if random modulation could sweep the waveform shape as apposed to just a cyclic LFO moving backwards and forwards.

Greg is right. Additive synthesis is nothing like using an LFO to modulate the shape of a waveform. Additive synthesis is acheved by adding waveforms with different pitches, harmonics and amplitude envelopes. The two concepts are similar in that they both have to do with combining waveforms, but the similarities end there.

Continuous waveshaping is a great feature, but does not sound at all like additive synthesis.

Greg and the Oyster are right regarding additive synthesis. But I stand corrected on the wave forms. I forgot about potmapping. That is a feature I just haven't wrapped my head around yet. I've been using it for this and that, but I haven't really exploited it yet. This has been a good lesson, and there it was in the new Tips article from the Squarewave Team! I would love to see so more ideas for potmapping. I still wish the indiv. waveform mods were available at the busses' pgm destination, however.

Hi Mark,

Take a look at the article on Pot Mapping on the SquareWave site. It's called "On The Map" - you can find it in the Voyager FYI folder. It includes a list of Pot Mapping ideas contributed from SquareWave members - could be just what you're looking for

I agree with you about the mod buss destinations, but these are hardwired AFAIK, and can't be changed. Fortunately for us, the Voyager's Pot Mapping and CV programming options provide workarounds for most of the things we like to do!

Cheers!

Greg
