The step-sequencer basics - Tonal sequences

2/8:Resol LastStep Style Start

Reso:16th Len:16

Once again you can either use the ”Len”-encoder to change your setting or do it

directly with the help of the numeric buttons [1]-[16], as long as the intention is to

change the length within a range of 16 steps. In case you have selected more than 16

steps, you can move the displayed section with the help of the (Tempo/Shuttle)-

encoder like a window along the complete line. Please note that the assignment of

this encoder can be changed from tempo-change to section-change using the encoder-

button. In case you wish to change the tempo from within the "Sequence-edit"-menu

all you have to do is push the (Tempo/Shuttle)-Button.

Adding a filtermodulation

By now you should be familiar with a number of options for controlling the settings of

the step sequencer. Still, our little Melody will become truly interesting, once you

start to animate the sound parameters in the next step employing the help of another

line. We’ll give this a try right now.

I. Let’s select the part “Analog Synth” by pushing the [Select]-button in

the "Part"-section plus numeric button [12]. The synthesizer-edit controls

are now assigned to the analog-synthesizer. Turn the frequency of the

24dB lowpass counterclockwise to 0, using the (Cutoff LP)-encoder.

You will hear very little of the original sequencer, as the lowpass is almost

completely closed.

II. In the "sequence-edit"-section chose sequencerline 16 “LpFreqEx2”.

This sequencer-line allows for the exponential control of the filter-

frequency.

III. Use a suitable step-envelope for the filter frequency modulation. For

instance you might want to chose a decay envelope with a length of 4

steps and an envelope depth of 18. The Display will show the following

message:

1/8:Fnc Trigger->LpFreqEx2

^Seq:L16 ^Type:Decay ^Len:4 ^Dpth:18

IV. Now, when you are pushing one of the numeric buttons, you should

be able to hear a significant change to the filter-frequency. During the

course of the sequence the filter-frequency will continue to shift relative

to the note-sequencer-line. To challenge you we have set the length of

this line at 15 steps, a little shorter than the actual sequence of notes;-)!

3.5 Step-sequencer advanced I

3.5.1Tonal sequences

The previous two chapters have introduced some of the basic functionality of

the step-sequencer. In the following chapters you will become familiar with

some advanced features. There are different types of sequencer lines available
