On menu page 15 you can adjust the portamento time. This time defines how quickly the pitch
glides between two notes.

THE OSCILLATOR ENVELOPE:MENU PAGES 16 - 19
On menu pages 16 - 19 you can control the oscillator envelope. The oscillator envelope has two
modulation destinations:
1.)
Pitch (Tune)
2.)
PWM (Pulse width modulation exp. Frequency of the auxiliary oscillators in sync option.)
Select menu page 16 of the oscillator menu. Here you can set attack of the envelope generator.
Edit Part1 OSC
<16> OSC-Att: 10
Lower values speed up the attack of the envelope and higher values slow it down.
On menu page 17 you can set the length of the decay. Lower values speed up the decay of the
envelope and higher values slow it down.
Edit Part1 OSC
<17> OSC-Dec: 10
On menu page 18 you can set how severe the modulation of the pitch envelope will be:
Edit Part1 OSC
<18> Pitch-EG:+0
The parameter allows positive and negative values.
On menu page 19 you can set how drastically the envelope influences the pulse width of oscillator
1. In oscillator sync operation this parameter influences the frequency of the auxiliary oscillator:
Edit Part1 OSC
<19> PWM-EG: +0
On the user surface of the POLYMORPH you find <ENV-MOD>. Depending on the operation
mode of the first oscillator this has different functions.
Oscillator 1 without sync: The pitch of all three oscillators is modulated.
Oscillator 1 with activated sync: Only the pitch of the auxiliary oscillators is modulated.
THE LFOS IN THE OSCILLATOR SECTION: MENU PAGES 20 - 27
The LFO is convenient for automatically varying a sound. Unlike the audio oscillators, the LFOs
create low frequencies beneath the audible range, which change the sound or the pitch cyclically.
Just about all of the LFOs are found on the user surface. This menu is only needed when the
modulation is to be used after an adjustable period when pushing a button. This offers parameter
„delay".
On the user surface both LFOs are selected with [PWM] or [VCO-FM].
The LFO waveforms are easy to demonstrate by modulating the pitch of the oscillators. The change
of the waveforms can be heard.
