OTHER MENU CHANGES

PORTAMENTO/TRIGGER Menu

MIDI Menu

MODULATION Menu

Changes to the [OSCILLATOR] menu are as follows:

This new function allows you to change the way oscillator 2 pitch relates to

oscillator 1’s pitch. The selections are:

Oscillator 2 pitch control can be used to set oscillator 2 pitch between 0-31 semitones above oscillator 1.

Oscillator 2 can be modulated and it’s phase is not related to that of oscillator 1.

Oscillator 2 pitch control can be used to set oscillator 2 pitch between 0-31 semitones above oscillator 1

and it is synced to oscillator 1. Oscillator 2 can be modulated.

Oscillator 2 pitch control can be used to set the ratio between oscillators 1 / 2 to one of six pre-set values.

This is always fixed and so oscillator 2 cannot be modulated.

All the controls and functions in the envelope / LFO sections are the same as DARKSTAR synthesizer. Please see
main owners manual pages 10 - 13 for full details.

Some of the other menu sections have small changes or additional features as follows:

There is an expanded monophonic multi-triggering mode now included in this menu.

There are three selections as follows:

In this mode only the first note played and held down will run the envelopes.

In this mode every new note played will run the envelopes.

As per [AUTO-GLIDE] feature detailed in the main DARKSTAR manual page 24.

In this mode the audio input level will run the envelopes.

This function (for adjusting the key/note of the internal oscillator) is now included in the MIDI

menu (features in the PART menu on DARKSTAR synthesizer).

There are now just two functions in this menu as follows:

This function allows you to set the amount of pitch modulation that

will be applied when the Modulation Wheel is used. RANGE = +7 to -7.

This function allows you to set the amount of pitch variation that will be

applied when After-Touch controller data is received. RANGE = +7 to -7

2. After-Touch - Pitch Mod Depth [AtPt]:

NOTE: if pitch mod source is set to

envelope 1 or 2 then the mod wheel will affect the amount of pitch envelope modulation.
