4. PITCH & SPEED
The Pitch controls the overall pitch of the source (PITCH: -64 st
to +64st) in addition to any pitch shifts introduced depending on
the key used to trigger the Source. The pitch controls increase/
decrease in single semitones. This can be then fine tuned by shift
clicking, and super fine tuned by shift + alt clicking. The speed
controls the speed (or tempo) of sample playback (SPEED: 0.25
to 4.0) relative to the DAW.
• SIMPLE INTERP:
uses linear interpolation of the sample
stream where both speed and pitch affect both perceived pitch
and the playback tempo of the sample. This is the most efficient
option and perfectly usable if pitch shifts are small and time-in-
dependent pitch shifting is not required.
• HQ INTERP:
uses high quality interpolation of the sample
stream where both speed and pitch affect both perceived pitch
and the playback tempo of the sample. This is the highest quality
option where time-independent pitch shifting is not required.
(This is the default for the sources.)
• TIME/PITCH:
this processes the time and pitch of the sam-
ple stream independently where the sample will be locked to
the tempo of the DAW and pitch shifting may be applied inde-
pendently of tempo changes.
5. FILTERS
These are two simple high-pass and low-pass filters which can
be applied to the source. HPF controls the cutoff frequency of
the high-pass filter (HPF: 0.0 to 24kHz), with the resonance of
this being controlled by the Q control above (Q: 0.5-10.0). Sim-
ilarly LPF controls the low-pass filter cutoff frequency (LPF: 0.0
to 24kHz), with the Q control above controlling the resonance.
NB - All parameters can be set by double clicking on
the value
6. GATES
There are two different types of gates within Phobos, with both
sharing the same Attack and Release knobs.
Gate Low
is a standard noise gate, with the gate opening when
the incoming signal is above the level of the threshold (THRESH-
OLD: -
∞
to 0.0dB), and reducing the signal by the sensitivity
when it is below (SENS: -
∞
to -20dB).
Gate High
does the reverse of Gate Low, whereby the signal
is let through unless it is above the threshold level. If above the
threshold level then the signal is reduced by the amount set on
the sensitivity knob. The behaviour of Gate High may seem unu-
sual at first, but when combined with the convolvers interesting
textures can be produced.
The
Attack
controls the speed the gate opens once either Gate
High or Gate Low is opened (ATTACK: 0.00 to 0.30s), and the
Release controls the speed the gate closes (RELEASE: 0.00 to
1.00s).
7. MAPPINGS
This opens the modulation mappings settings discussed in the
‘modulation mapping’
section.
8. RANDOMISE
This will randomise the parameters on the sound ±10% of the
current value.
