FLEX: Shifts both voices up one octave.
HarPeggiator
HarPeggiator creates dual 16-step arpeggios that combine three elements:
Dual 16-step pitch-shift sequencer
Dual 16-step rhythm sequencer
Dual 16-step effect sequencer
HarPeggiator lets you choose from a list of pre-programmed sequences for pitch, rhythm and effect.
Using the many possible combinations gives you quite a bit of creative control. That writ, it’s important to
understand the underlying concepts or you’re likely to spend quite some time scratching your head.
First off, we suggest that you experiment with only one voice (e.g. A) and the pitch sequence only. To do so,
turn OFF the rhythm and effect controls. This is important because, by de
fi nition, for many rhythms not
every step in the sequence is played. For example, you could select a rhythm that divides the 16 steps
into four bars of quarter notes and only sounds the
fi rst step (note) of each bar. As a result, although the
pitch sequence is 16 steps long, only four notes will sound. Also, use the Length control to set an
appropriate length for each step so that you can clearly hear the pitch at each step.
The Pitch Sequence controls select one of 27 pitch sequences for A/B. These are selectable presets
numbered from 01 to 26 plus a random sequence. Set to minimum to turn off the pitch effect.
For the majority of pitch sequences each step is a fi xed pitch. However, the H90 has the ability to glide
the pitch within any step. This feature is used in several of the sequences. The last sequence is a random
sequence of pitches.
When selecting pitch sequences, it is best to fi rst turn OFF both Rhythm and Effects sequences so that
the pitch sequence is unaffected by these parameters. As always, your ears are the best judge of what
works.
The fi rst several pitch sequences are fairly straightforward. Here’s a general description of each of these
sequences:
All steps are one octave up.
All steps are one octave down.
All steps are a
fi fth up.
