which envelope is being assigned to each trigger group. From here in a trigger group can
be played as a Part. The long and short of it is that now you don’t have just one single
analog Part available – as in the original release version of the Spectralis - but a total of 3
analog Parts with numbers 12, 13, 14
Oscillators:
When you assign a n oscillator to the trigger group the following happens: If the trigger
group is being triggered (via MIDI notes, the built in Mini Keyboard, the step-sequencer
or by a Motiv of the pattern sequencer) the trigger group transmits the received pitch
information to the oscillator and triggers its envelopes (pitch-envelope and level-pitch).
This oscillator can now not be accessed by the other trigger groups. Pitch-bend,
after-touch or modulation-wheel data of course are also transmitted to the selected
oscillator.
24dB LP-Filter and Multimode Filter
The process works similarly with the two analog filters. The cutoff-and level-envelope
of the filter are being addressed by the selected trigger-group. Its pitch-information
controls a possible keyboard scaling sensitivity and all other MIDI data are being
processed as expected as well.
Filterbank and Noise
Things work a little different with the filter-bank and the noise source. As these two
sections don’t utilize pitch and have no parameter which could be controlled by standard
MIDI controllers, only their level-envelopes are being triggered. You might ask yourself
why we’re going into such detail to describe this subject. Basically most of it sounds
like normal MIDI multimode. There are distinct differences though. For one it is up to
you how you are assembling a voice and additionally a trigger group does not
automatically determine the routing of the audio signals. When you are assigning an
oscillator and the low-pass filter to a trigger group, you have to make sure that the
output signal of the oscillator is being inserted into the lowpass-filter. Otherwise you
might experience that there is no audible signal even though you have assigned both
sound components to a group. No need to panic! We already have programmed a
number of finished useful examples of multimode sounds, which you can use right
away – to get started. You will locate these sounds in the category “Multi”. For sounds
in this category multiple trigger groups are being used, to generate multiple sounds
simultaneously and independently.
3.7.1 Playing the triggergroups
If you select the analog Part in part-select mode (
[Part-
numeric button
[12]
)
you in fact are selecting Part 12. If you want to access another analog-Part and to change
the trigger group, hold down numeric button
[12]
for a little longer. You will then see
another menu in the display for he selection of the Analog-Parts 12-14 resulting from the
trigger groups
