Keyboard/Voice
• Oct -/+: These buttons control the key range available along the keyboard.
Tip: You can use this while holding notes to access unavailable notes. Particularly handy
when used in conjunction with Sustain and Chord mode.
• Transpose: Holding the ‘Mod’ button and ‘Oct-’ button together enters Transpose mode.
Here you can directly transpose the pitch of both oscillators using the keyboard. C2 is
the default position. Keys below this transpose down 1 semitone per key and keys above
transpose up 1 semitone per key.
Note: Using transpose will not trigger a new note. If you are using low EG settings you
may not notice the change. This can be used to great effect while sequencing the synth
from its Arp or Seq or from external sources.
Note. Pressing Transpose without entering any key values will reset transposition to 0.
Transpose is a performance feature and as such is not saved per patch. It will remain until
it is either reset, turned off or the unit is power cycled.
• Sustain: Pressing ‘Oct-’ and the ‘Oct+’ button together will enable / disable Sustain.
• Sustain ‘Latch Mode’: Holding ‘Oct-’ and holding the ‘Oct+’ button for one second will
enable Sustain ‘Latch Mode’ - press and release a note / chord to sustain it, press a new
note / chord to overwrite the existing one. This also provides the classic arpeggiator ‘Hold’
functionality.
• Glide: Holding the ‘Patch’ switch and turning the ‘Mix’ encoder controls the speed with
which the oscillators change their pitch, ‘sliding’ from one note to the next one pressed.
Positive values control the amount of Auto Glide and negative values control the amount
of Legato Glide and will only glide if another note is already held.
• Voice Mode: Hold the ‘Patch’ switch and press the ‘Mix’ encoder switch to cycle through
the different Voice Modes.
Mono: Only one voice of the 5 voice engine is played.
Poly: Polyphonic voice mode for the current patch. 5 voice true polyphonic path into a
stereo FX engine input.
Unison: Monophonic voice modes where multiple voices are stacked and detuned, the
number reflects the number of voices per note.
Stack: Polyphonic voice mode where 2 voices are stacked for 2-note polyphony.
• OscDrift: This encoder controls the oscillator drift amount. This is the amount of slop or
random detuning of each oscillators phase and tune.
Audio Output + Gain
The Gain Boost setting applies to all patches and increases the average output level.
The Patch Gain control, allows you to balance even the quietest patches, and dramatically
improved the audio quality while decreasing noise floor, so adding gain from external sources
won’t introduce unwanted noise.
Because COBALT5S employs a limiter as the final stage before output in its audio signal path,
headroom for dynamics might be reduced as a result of higher gain levels.
Note: The main outputs on COBALT are designed to output Line Level signals
• Patch Gain: Per-patch gain adjustment for balancing patches relative to each other.
Values in the range 0-100 should be transparent to use on any patch that needs it,
moving the control past 100 can begin to saturate the limiter on some patches. Note that
this can be used creatively.
• Gain Boost: Global gain boost that increases average output level. There are 3 settings:
Off - full dynamic range
On - boost to output volume (Default Setting)
Gain boost setting will be saved automatically
• Headphone Volume: Headphone output volume can vary dramatically depending on
which model of headphones is connected. This global control adjusts the output range of
the headphone out to compensate for this variance and prevent unsafe listening levels.
• Main Volume: Master output volume of the synth, post limiter. Controls the output
volume of both the headphone out and the main outputs. For best signal to noise, set
this to 127.
