SPECTRALIS 2

3.4.1 Step-sequencer basics - Filterbank rhythms

The parameters of the step-sequencer are an integral part of rhythmic modulated

hybrid synth patches and are stored therefor inside the hybrid synth sound memory.

That is the reason why we have included it’s description in this Analog Synthesizer

"How to...?"-chapter.

As a preparation for the first part of this "Step-Sequencer"-chapter you can either

use the settings prepared in the preceding "Filterbank"-chapter or your will have to

make the following preparations now:

I. Select an empty pattern in an empty song

II. Select the "Analog"-synthesizer using the [Select]-button plus

Numeric Button [12] .

III. Push the [OSC WAVE]-encoder-button and select successively

menu-pages 3-7 with the [Page-Up]-button, to set the levels of the

oscillators for all filters to 0.

IV. Now select menu-page 23, where you can use the first display encoder

to adjust the filterbank-volume (FB) for noise to a value of 200.

V. In the "Filterbank"-section you should now push first the [Level]-

button and then one of the encoder-buttons [1] to [10], to open the Filter-

bank menu.

VI.) Set the Parameters “FbQ” and “FbFs” to “0”.

VII. As a final step in your preparations set the bypass parameter ”FBBP”

at the this menu-page of the filterbank menu to a value of 255.

We will now use the step-sequencer to automate the gain control of the various

filterbands.

Select the [Function]-button in the sequence-edit section. You will see the following

display message:

1/8:Fnc TrigMod->FBV LP Stp:1-16

Seq:L01 ^Type:Decay ^Len:4th ^Dpth:63

If the Sequencer is already playing, you can now set the levels for each 16

note of

the running sequencer using encoders (1) through (16). We won’t do that right now

though, but we will deal with an even better option for Level-Control – the step-

envelopes.

The step-envelopes of the Spectralis are a somewhat unusual feature for a step-

sequencer. They permit the triggering of tempo-based mini-envelopes, which are

independent of the note-triggering of the synth work in addition to the already existing

envelopes in the synthesizer parameter section. What makes this feature even more

special is, that the envelope-direction, curve-shape and duration for each step of the

sequencer can be different. Independent envelope triggering for each filterband

amplifier provides an excellent option to create complete drum grooves from simple

white noise. The following Parameters can be found on the first sequencer-edit page:

SEQ: This is where you can select the Sequencerline, which you would

like to work on in the Editor. The stepsequencer has 24 sequencerlines

with free assignable routing targets, you can choose from.
