Global section
The Global section contains parameters that affect all voices. It contains two effects,
an open filter slot, the Global Envelope and LFO 2.
Effects section
There are two global mono in/stereo out effects, a Delay and a Chorus. These effects
affect all voices coming from the Amp section equally if activated. The effects are
placed after the Global Filter in the signal chain.
D There are controls for standard Delay/Time and Feedback parameters.
Chorus vs. Delay differ only in the delay time range - Chorus is for chorus effects,
i.e. short delays, whereas Delay produces echo effects.
D Delay Time can be Tempo Synced.
This is set with the Tempo Sync button - if on the delay time is set in beat resolu-
tions synced to the main sequencer tempo.
D The Delay and Chorus effects can also be pitch modulated by a built in
LFO (the “Mod” parameters).
“Rate” controls LFO speed and “Amount” the Stereo width.
D Dry/Wet governs the balance between the unprocessed (dry) signal and
the effect (wet) signal.
Global Filter slot
This is the Filter 3 slot which can be loaded with one of the filter types. Filter 3 is ba-
sically set up as the other filter slots. The difference is that all voices are mixed to-
gether before entering the filter. The “ENV” parameter governs modulation by the
Global Envelope. If you play one note the filter envelope will trigger. Adding new notes
while a note is still held down (legato) will not trigger the filter envelope.
See “Filter slots” for a description of the filter types.
Global Envelope
The Global Envelope 4 is an advanced envelope that is free to use for whatever pur-
pose, but remember it is “single trigger” so it will not retrigger legato notes as ex-
plained above. It is an ADSR envelope with a pre-delay stage and a hold stage before
the decay phase. You can make it Loop and Sync the time settings to the song tempo.
Apart from standard ADSR parameters, the Global Envelope has the following param-
eters:

Description
Delay This can set a delay before the onset of the envelope.
Loop If this is activated, the envelope phase from Delay to Decay
will continuously loop.
Hold This allows you to set a “hold” phase before the Decay.
Tempo Sync If this is on, each stage will have a length that corresponds
to beat increments of the current sequencer tempo. E.g. you
can have a 1/4 delay before a 1/16 attack phase followed
by a 1/8 decay. Each stage can be set a range from 1/32 to
4/1 (4 bars).
If this is off, the envelope times are free running and can be
set in seconds (same time ranges as for the Filter Envelope).
Gate Trigger The “Gate Trig” button can be used to switch off the enve-
lope triggering from notes and allow the envelope to be trig-
gered by some other parameter. This button is normally
activated.
