Creating PWM on the XW-P1 and XW-G1

We’re still finding exciting ways to make new sounds on the XW-series.

In HexLayer mode the XW-P1 is essentially a sample based instrument. The waveforms it provides are digital recordings. While the range of waveforms is quite vast, they are “static” samples….meaning it is impossible to change a waveform’s shape over time the way an analog or virtual analog synthesizer can. Or at least it appears that way on the surface.
If you dig deep into the collection of over 700 waveforms the XW-P1 provides in HexLayer mode you’ll find a wide variety of waveforms, may of them appear to be similar.  On the surface combining two different sawtooth waveforms as an example allows the XW-P1 to have a richer sound than using two identical waveforms. Some of those sawtooth waveforms however are not like the others, which can allow for some exciting new sounds.

The XW-P1 provides a number of sawtooth waveforms actually reverse or inverse sawtooth waveforms. When they’re heard one at a time, it would be nearly impossible to distinguish between the regular sawtooth and the inverted one. When you combine them, this is when the magic happens.

From the Sound on Sound “Synth Secrets” article on PWM.

If the two waveforms are 100% identical, when they’re combined they actually cancel each out completely – you wouldn’t hear anything at all.  As soon as you begin adjusting the pitch of one sawtooth vs the other the combination creates the PWM effect.  This picture taken from Sound on Sound Magazine’s Synth Secrets article isn’t 100% accurate but essentially shows the result.

This method can also be applied to the Solo Synth in both the XW-P1 and XW-G1.  Utilizing this technique you can create some very BIG and rich sounds. Using the technique described above You will however reach a point detuning the two waveforms from each other where it will sound less like a PWM effect and more like two waveforms that are simply far out of tune from each other.  Luckily there is another method that can be utilized in Solo Synth mode to achieve a PWM effect with a faster cycle.

To do this create a Solo Synth tone with two identical sawtooth waveforms. On one of the Oscillators, scroll down and find the LFO2 Depth.
 
Next, leave Oscillator Edit and go to the LFO2 page (picture taken from PX-5S) and make adjustments as shown. LFO PWM  You can adjust rate and depth to taste but now you have a faster PWM effect.
These are only a couple of applications that can lead to some really remarkable PWM sounds.

Additional audio examples along with sounds to download for your XW-P1 and XW-G1 are coming.

XW-P1, XW-G1 Controllable Feedback Loop

The External Input on the XW-series has many possibilities but here is one that perhaps you had not thought of before.  Plugging the output of the XW, into the External Input to create a feedback loop.

A note of CAUTION before we go any further – the following process can create some serious, high level noise.  Please lower your listening levels to a minimum level before proceeding.

First to listen to this experiment, you’ll want to listen to the XW from the Headphone output.  This is what should be connected to your mixer, speakers or of course your headphones.  You’ll want to use a Solo Synth tone with the External Input enabled.  Note that the XW’s instrument and Mic Inputs are always active unless you select a tone with the External Input enabled.  So you’ll get Feedback on ALL TONES if you’re not careful.  If you’d like the Solo Synth tone used in the video, download it here:  http://www.casiomusicforums.com/index.php?/files/file/585-xw-feedback-looper/.

Second Warning: LOWER THE VOLUME.   The Left/MONO output should be connected with a 1/4″ cable to the Mic Input or Instrument Input on the back.  Now when you play this sound and raise the level of the External Input you’re creating a feedback loop.  Slider 5 on the XW-P1 can control the level of the feedback loop.  On the XW-G1 you’ll have to select the 5th Oscillator then use the Level Control.  As an alternative, you could also put an Amp Envelope on the External oscillator so this effect fades in over time or assign another controller such as the modulation wheel to control the level of the feedback.  Have fun and if you come up with some interesting sounds, post links in the comments below to share.

Here is an example:

 

XW’s and ACID House

The capabilities of the XW-series specifically for House or ACID house are quite incredible and mostly untapped. With the recent craze for some re-issued products, here on our blog we’ll be showing you a number of things that the XW’s have been able to do all along, in their own unique and powerful way.

The first two core essential components in this genre are drums and bass. The TR-808, TR-909 and other drum machines sounds were often used. Both XW’s provide these kinds of sounds first place to look are the Synth Kit1 and Synth Kit2.  TIP: On these kits, be sure to use the -octave switch to find an additional kick on note B1.
The XW-G1 does have the overall advantage when it comes to drum sounds. Not only does it have more built-in drums but you also have the opportunity to supplement those using its sample memory. Take a look at some of the sounds available for download at http://www.casiomusicforums.com

Next, the XW’s Solo Synth can provide the next core ingredient for the sound of the baseline. The oscillators in the XW’s provide a wide assortment of waveforms including some specifically from the TB-303.  Since the XW’s architecture allows for 4 waveforms at once, you can blend these or switch between them live to create bass sounds far beyond the traditional.   Tip: The secret to really getting the XW’s bass sound to squeal like the original TB-303 is the Distortion DSP effect. The TB-303 didn’t become famous because it sounded good in a traditional way, but because it sounded NASTY in a good way. The XW’s Distortion effect can be used to really bring these sounds to life.

Here is a quick example using the XW-P1.

In the next article, we’ll discuss the differences between the XW series and the advantages of the XW-G1 over the XW-P1 for this style of music.
