SpacyShifters

[tim]

This patch processes incoming audio via four high quality DIY pitch shifters, each based on a 1 second delay line. This large amount of delay time means that transients are totally garbled, but there are none of the ugly "flangey" artefacts usually associated with this type of processing.

The outputs of these four pitch shifters are blended together by a twodimensional XY "joystick-type" crossfader (eg. like the joystick on the Prophet VS and others). This mix is then fed back into the shifters, resulting in a gradual buildup of increasingly complex intervallic structures and generating an organically evolving tonal (or not so tonal, depending on semitone settings) ambient drone around the input. Tweaking the XY crossfader creates caleidoscope-like changes in the spectrum, as different pitch shifters (with different shifting amounts) come more or less into prominence. Experiment with different shift amounts for different tonalities and quasi-chords.

The feedback loop is pretty stable. However, I threw a limiter in there too, just to be safe.

The pitch shifters also feature subtle modulation for chorus-like thickening of the sound within the feedback loop. There's a chorus/delay at the end to add a stereo image to the sound.

Controls:
Page A1:
INPUT and OUTPUT section. Self-explanatory (I hope ).
Page A2:
SHIFT 1 - 4: Semitone shift amount of the four pitch shifters
VECTOR X,Y: position of the joystick-type quad-crossfader
FEEDBACK Level: Amount of feedback into the pitch shifter network
SHIFTERS Dry/Wet: balance between original and processed audio
Page A3:
MODULATION Speed, Depth: subtle pitch modulation of the shifters.
Page E1:
DELAY dry/wet, time, feedback, damping frequency, modulation depth and rate controls

Only one variation, with my personal favourite setting.

Uses one DSP.

have fun.

Awesome, again!!

Just added three sine wave oscs (tuend differently) to the poly area, routed through the bus and voila instant trippy pads.

and finally a really good use for my x-y controller.

Fab work fella.

Thanks

TK = pushing the limits... again!!

Thanks

I'm speechless, who needs an eventide now?
