10.8 AMP PAGE 2
The AMP page controls parameters for the amplitude envelope reset, envelope mode, and track routing.
Press [AMP] twice to access this parameter page.
10.8.1 AENR
Amp envelope reset sets the amp envelope behavior:
ON resets the envelopes for each consecutive trig (default).
OFF does not reset the envelopes for each consecutive trig.
10.8.2 MODE
Envelope mode sets the amplitude envelope to function as either an AHD or an ADSR envelope.
10.8.3 ROUT
Track routing sets if the track’s audio should be routed to the Analog FX block or the Main mix. For more
information, please see “5.4.1 ANALOG FX BLOCK ROUTING” on page 18.
A machine in Syntakt is a full-blown synth engine designed for a specific purpose. A drum-
oriented machine has direct access to a decay parameter for shaping the amplitude, as
this is so central to the character of a drum. Each track also has an additional amp enve­
lope. Selecting a drum-oriented machine will default the amp envelope to an AHD envelope
with infinite decay.
A typical synth machine requires a more complex envelope shape and is more prepared to
be used with a keyboard to control note length etc. Therefore, when selecting one of the
SY machines, the amp envelope will default to an ADSR envelope with a typical setting for
release time.
All Digital machines and most Analog are designed to work well with both an AHD en­
velope and an ADSR envelope. With AHD selected they will perform like a drum with a
defined time before the decay. With ADSR selected they will perform more like a synth
voice with keyboard control over note length and sustain before the release. The voice
then plays until the note is released.

The Low-Frequency Oscillator can be used to modulate the parameters found on the audio tracks SYN,
FILTER and AMP pages. Customize the low-frequency oscillator behavior, orientation, and depth on this
page. This page controls the behavior of LFO 1.

10.9.1 SPD
Speed sets the speed of the LFO. Try settings of 8, 16 or 32 to sync the LFO to straight beats. The knob
is bipolar. The LFO cycle can be played backward by using negative values.
10.9.2 MULT
Multiplier multiplies the SPD parameter by the set factor either by multiplying the current tempo (BPM
settings), or by multiplying a fixed tempo of 120 BPM.
10.9.3 FADE
Fade In/Out makes it possible to fade in/fade out the LFO modulation. The knob is bipolar. Positive val­
ues give a fade-out, negative values give a fade in. 0 gives no fade in/fade out.
10.9.4 DEST
Destination selects the modulation destination for the LFO. Preview how the LFO modulation will affect
the sound by highlighting a destination. Press [YES] to confirm the selection. For more information,
please see “APPENDIX C: LFO MODULATION DESTINATIONS” on page 119
10.9.5 WAVE
Waveform sets the LFO waveform. The Triangle, Sine, Square, Sawtooth, and Random waveforms are
bipolar. The Exponential and Ramp are unipolar.
10.9.6 SPH
Start Phase sets the point within the wave cycle where the LFO will start when it is trigged. 0 makes the
LFO start at the beginning of a complete wave cycle, 64 makes it start at the center. A small square at
the start of the waveform shows that the wave cycle starts at a zero-crossing point. If WAVE is set to
RND then the SPH parameter changes to SLEW and adds slew to the transitions in the waveform.
10.9.7 MODE
Trig Mode sets how the LFO will act when a note is trigged.
• FRE is the default free-running mode. It makes the LFO run continuously, never restarting or
stopping even if notes are trigged.
• TRG makes the LFO restart when a note is trigged.
• HLD makes the LFO run free in the background, but when a note is trigged the LFO output level is
latched and held still until the next note is trigged.
• ONE The LFO starts when a note is trigged, then runs to the end of the waveform and then stops.
This makes the LFO function similar to an envelope.
• HLF The LFO starts when a note is trigged, then runs to the middle of the waveform and then stops.
10.9.8 DEP
Depth sets the depth and polarity of the LFO modulation. Both negative (inverted) and positive modula­
tion depth is possible. A setting of 0 equals no modulation depth.

The table below shows the LFO speed measured in whole note values. One whole note equals 16 se­
quencer steps in 4/4 with SCALE set to 1x. I.e., a combination of SPD and MULT (set to a BPM value)
settings that generate a value of 1 in the table gives that the LFO will do one full cycle in the time it takes
the sequencer to advance 16 steps.
