effect. Similarly, with fretless bass, the portamento pedal may be used to slide
notes whenever you please.
TIP: This may also be used to good effect to simulate the TB303 bassline synth so loved in
dance music. One of this bass synth’s most distinctive features was (is) the programmable glide
effect. To create this sound, take a simple, single sawtooth or square wave sample (no detune -
the TB303 has only one oscillator), add simple filtering (preferably highly resonant) and a
simple envelope and use the footswitch control of portamento to switch glide on and off at
suitable moments.
This sets the speed of the portamento. It is difficult to specify its range as this
depends on the setting of the parameter described below but the
longest portamento effect you can have is over 30 seconds. You will note that
if this parameter is set high but you play notes quickly, the portamento effect
may be so slow that your notes never hit the right pitches! If you anticipate
playing a particular sound quickly, set lower portamento rates.
Here you may select two different portamento types, TIME and RATE.
TIME sets the portamento effect so that the speed of the effect is constant
regardless of the interval played. For example, if the rate is set to give a glide of
1 second, it will take one second to glide up a semi-tone or seven octaves. For
example:
1 sec
1 sec
1 sec
1 sec
1 sec
When TIME is selected
When set to RATE, the speed the effect takes depends on the interval. For
example, if it takes one second to cover an octave, it will take two seconds to
cover two octaves, four seconds to cover three octaves, eight seconds to
cover four octaves, etc.. For example:
1 sec
2 secs
4 secs
8 secs
16 secs
When RATE is selected
You may use these two portamento modes to create a range of different
musical effects.
