The Envelopes Menu
Envelope Triggering (Menu Pages 5, 6 & 7)
These functions only apply to a sound which has been set up to
behave in a monophonic manner (see Voice Mode on Page 23).
When the Voice mode is set to any of the Mono options, different enve-
lope triggering options are available for legato playing styles (notes
overlapping).
When the first note of a musical phrase is played, it might be desirable
to have both the Amp and Mod envelopes trigger. For the remaining
legato notes,just the Mod envelope re-triggering would create the effect
of the phrase becoming quieter and quieter.
When these are set to SGL (single), the appropriate Envelope will only
be triggered when the first keyboard note is played. Any subsequent
legato style key presses will not re-trigger the Envelope.
When set to MLT (multi), the appropriate Envelope will always re-trig-
ger on each key press, regardless of the playing style used.
FM Env Attack (Menu Page 8)
When FM synthesis is being used (see Page 24), this value determines
the FM Envelope’s Attack time.
Note : The FM Envelope is used only for FM synthesis and should not
be confused with the Amp or Mod Envelopes available on the K-
Station’s front panel.
FM Env Decay (Menu Page 9)
When FM synthesis is being used (see Page 24), this value determines
the FM Envelope’s Decay time.
Note : The FM Envelope is used only for FM synthesis and should not
be confused with the Amp or Mod Envelopes available on the K-
Station’s front panel.
Audio Input Triggering (Menu Page 10)
The K-Station is capable of processing an external audio signal
through its Filter and / or Effects section. However, it should be remem-
bered that the Amplifier is controlled by the AMP ENVELOPE controls
on the front panel. Unless the Amplifier has been triggered (usually by
playing notes on the keyboard or from a sequencer), the Amplifier will
be set at a zero volume level and no audio signal will be passed
through it.
This is not a problem when the external audio signal is to be passed
solely through the Effects Section (since the Effects come after the
Amplifier in the K-Station’s audio signal path). However, if it desired to
process the external audio signal through the K-Station’s Filter, it is
often convenient to be able to automatically trigger the Amplifier and
Mod envelopes whenever an external audio signal is present.
Setting this function to ON automatically triggers the Amp and Mod
Envelopes (thus opening up the Amplifier) whenever the external audio
signal strength reaches a certain threshold level. This feature ensures
that it is not necessary to play the K-Station from its keyboard or a
sequencer in order to hear the external audio signal processed through
the Filter.
The setting of the threshold level (sensitivity to external audio strength)
is done by adjusting the Input Trigger Sensitivity value found within
the Global Menu. See Page 36 for details.
When the Envelopes are auto-triggered in this way, the K-Station actu-
ally ‘plays’ a default note of Middle C. If the Mixer levels of any of the
three Oscillators are set above zero, a pitched element to the sound
will be heard (pitched at Middle C) whenever the Amp Envelope is
auto-triggered. To remove this, make sure each of the Oscillator Mix
levels in the Mixer Section are set to zero.
See Page 35 for more details of using external audio signals with the
K-Station.
External Audio To Effects (Menu Page 11)
This function determines where the external audio signal is fed into the
K-Station’s audio signal path. There are two possibilities.
1. Feeding External Audio Directly To The Effects
The external audio signal may be fed directly to the K-Station’s Effects
section, bypassing the Mixer, Filter and Envelopes. Once the input sen-
sitivity has been set for the input device (see Page 36) turn the the
DATA knob until the display shows ON. The external signal should now
be heard at the outputs. It may now be processed by all of the various
effects including the EQ Filter.
2. Feeding External Audio Through The Filter
Setting this function to OFF, feeds the external audio signal into the K-
Station’s Mixer and Filter section. In order to hear the filtered signal,
repeatedly press the SOURCE button in the Mixer section until the
EXT INPUT LED lights and turn up the LEVEL knob. The K-Station’s
Amplifier also needs to be triggered by the Amp Envelope. This is done
either by playing a note on the K-Station’s keyboard, playing in a MIDI
note message from a sequencer, or setting the Amp Envelope to auto-
trigger when an external audio signal is present. See the function
Audio Input Triggering described above for details on how to do this.
Once an external audio signal has passed through the K-Station’s
Filter, it can still be processed by the Effects section in the same man-
ner as any other audio source (Oscillator waveforms etc.).
See Page 36 for more details of using external audio signals with the
K-Station.
