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.
