Pitch Shifter - OTO Biscuit User Manual

You can still set your delay feedback when the « F3 » switch (Freeclock) is on.
Press the « +/F2 » (Feedback) switch (that flashes red) and set your delay
feedback by moving the CLOCK pot (cf +/F2 : FEEDBACK).
The « F3 » switch still lights up red and has saved the last freeclock
setting.

By pressing the « F2 » switch again you go back to the freeclock function. The
CLOCK pot's physical position may very well be different than the previous
freeclock setting, since you moved it to set the delay feedback.

To prevent a sudden jump of the delay time, the CLOCK pot will not be
active until it reaches the previous value. The BYPASS switch will briefly
turn blue to indicate this.
NB : BISCUIT modifies the delay time by changing its sampling frequency.
The longer the delay (slow tempo and dotted quarter note), the lower
the sampling frequency. Some aliasing may appear when the input signal
contains H.F. harmonics.

3.3 PITCH SHIFTER

An « Old School » 8-bit transposition is applied to the signal. Only the left
input is used, the pitch shifter output is sent on both left and right outputs
and can be mixed with the direct signal.
The 1 to 4 switches are inactive in this mode.
Only the CLOCK pot is used in this effect. It selects the transposition value,
indicated by one of the 8 switches lit up white.

1/ 2 Octaves down (C 1)
2/ 1 Octave down (C 2)
3/ 1 Fifth down (F 2)
4/ Detune : signal is transposed by some hundredths of a semitone (C 3)
5/ 1 Minor third up (D #3)
6/ 1 Major third up (E 3)
7/ 1 Fifth up (G 3)
8/ 1 Octave up (C 4)
NB : You can also select the transposition value by using a MIDI key-
board. The notes are written between parentheses.
