SPECTRALIS 2
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-Select]+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
1/4:S06:<Song06>PA05:WetSolo Pa12
[Part12] [Part13] [Part14] [CURRENT]
Using the rotary buttons 1-3 below the display select the desired Part according
to the trigger group. You will see the currently selected Part in the upper right.
