Patch Ideas
Resonant Delay (Waveguide, Karplus-Strong)
Basic Resonant Delay
Resonant Delays are delays with short delay time (in the audio range) and enough feedback to create a
resonant sound somewhat like that of a plucked string.
The Looping Delay supports resonant delays. Simply tap a very fast tempo and flip the Time switch to
1/8. Alternatively, feed a square wave LFO into the Ping jack. The LFO should be in the low or mid
audio range, around 20-50Hz is the most stable, but up to 500Hz will work.
Next, feed a signal into the In jack: a noise burst or a short sample from the STS or Sampler (Length
set near minimum) is an excellent sound source. You also can use a trigger (keep in mind the amplitude
of the trigger will effect the sound).
Use the Time switch and knob to set the pitch. Feedback sets the resonance, and Delay Feed effects
the level and resonance as well. Make sure Inf. Hold is off. The frequencies present in the input signal
can ring loudly at particular settings, so be prepared for surprises!
If you consistently have unstable results when using an external clock into the Ping jack, try setting the
External Clock De-jitter setting to a different value. Small amounts of jitter in the external clock can
cause large changes in the sound.
Playing Resonance With a Keyboard or Sequencer
Holding down Inf. Hold and turning the Time knob changes the Looping Delay into Unquantized Time
Mode (see section on page 10 for discussion). This feature is great in combination with Resonant
Delays. First, get a nice resonant delay sound happening. Then hold down the Inf. Hold button and
turn the Time knob slowly. You should hear the pitch of the resonance change smoothly (not stepping
through quantized pitches). Now, plug a 1V/octave keyboard or sequencer output into the Time CV
jack. Plug the velocity output (or an envelope output that's triggered by each step of the sequencer) into
the Feedback jack. Turn down the Feedback knob so that the velocity/pressure or the envelope make
the Looping Delay create individual "notes". You can also patch into Delay Feed to get a different
effect.
Sound on Sound Looping #1: Creating and Removing Layers
With the Looping Delay you can build a loop by layering audio on top of itself. Since the Looping
Delay is always recording when not in Inf. Hold mode, each time you add a layer, the audio will be
recorded. You can then use the Windowing feature to scrub backwards in time, essentially peeling off
newer layers, or scrub forwards to restore the layers.
Tap a tempo on the Ping jack of about one second. Turn the Time knob to 8, and flip the Time switch
to = (center). This creates a loop of about eight seconds (or eight "bars", if you consider the Ping clock
to be one bar). Make sure Inf. Hold is off.
Start with Feedback at 90-100%, Delay Feed at 100%, and Mix at center.
Play a sound into the In jack. It can be a short burst, a drone, random noises, anything. Since you'll be
layering more things on top, try to keep it under 8 seconds when you do this the first time. After you
finish, press Inf. Hold to lock the loop in. If you want all your layers to be 8 bars each, then only turn
Inf. Hold on or off when you see the red light go from off to on.
Tip: Enabling Quantized Change Mode will force enabling/disabling Inf. Hold to happen exactly on the
Ping clock (which happens every second). You also could wait until the red light goes off, patch Loop
Clk Out into the Hold jack, and then unpatch it after the red light goes on.
You should now be hearing the sound repeating every eight seconds.
