Live Mode, the function button swaps between the two live modes
when an SD card is not installed.
While the LED is lit the hold mode is enabled, it samples the current
grain at a positive going edge on the reset input and continues to
play this until a negative going edge ignoring any changes to the
window depth or width while held. Note, the buffer will overflow if
the hold is maintianed for many seconds and the grain will glitch as
it jumps to the new data.
Swapping to the record pause mode (LED unlit), holding the reset
input high will disable filling the buffer. This can be used to sample
live sounds for manipulation as all functions operate as normal, but
while paused all incoming sound will be lost.
Playback Mode, the function button cycles through the wave files
stored on the SD card if inserted. Once a file is loaded the card can
be removed and the sound will remain in memory until the function
button is pressed again to change mode or load another sound.
Files named W0.WAV to W9.WAV stored in the root directory of the
card will be loaded in sequence one at a time. They must be 16 bit
mono wave files in the .wav format, the sample rate is ignored and
up to 500,000 samples can be loaded into the buffer for realtime
manipulation.
Interpolation, holding in zoom (+ or -) when loading a waveform
or changing modes will enable interpolation of the output audio.
Dozens or less, maintains only tonal information
window size can create strong formants.
Hundreds, microsound fragments that are hard to
identify their source.
Thousands, sample fragments where the source
is clear but rhythmically devoid.
Tens of thousands, sampling maintaining the
rhythmic context of the source material.
Grain size, has a strong effect on the
resultant sounds, adjusting the window
size dramatically changes the result.
