PRESONUS S1 Artist 3.0 [295/307] Studio one reference manual

There is also a Sub Oscillator knob, which can be adjusted from 0 to 100% to add more low frequency content to the

sound.

The Portamento section lets you control pitch slewing between notes. Using the mode selector, you can choose between

three modes:

Off A note that is played while another note is playing silences the previous note and trigger the new one.

Legato An overlapped note does not trigger a new envelope but the pitch slowly changes to the pitch of the new

note.

Retrigger An overlapped note retriggers the current envelope, starting at its volume at the moment it is ret-

riggered. This also slowly changes the note’s pitch. Note velocity is not applied or updated for overlapped notes.

The Time knob adjusts the glide speed (that is, the duration of the pitch change) when using portamento. The range is

from 5 ms to 1 s.

Amplifier

Below the Oscillator section is the Amplifier section. This consists of a Gain control, which responds to MIDI Volume

messages, and a Velocity-to-Volume control, which modulates the volume of a note in response to key velocity.

The most important part of this section is the ADSR envelope. (“ADSR” stands for “Attack, Decay, Sustain, Release.”)

With these four sliders, you can adjust the amplitude characteristics over time. These characteristics play a huge role in

defining the overall sound. The ADSR envelope can control the volume of a played note and can also control the filter

cutoff.

A Adjust the attack time, which is the time required for the sound’s amplitude to go from zero (silence) to full amp-

litude. The range is from 2 to 500 ms.

D Adjusts the decay time, which is the time required to drop from full amplitude to the sustain level. The range is

from 2 ms to 1 s.

S Adjusts the sustain level, which is the level that is held from the end of the decay until the key is released. The

range is from -96 dB (silence) to 0 dB (full amplitude).

R Adjusts the release time, which is the time required to fall back to silence after the key is released. The range is

from 2 ms to 2 s.

Filter

The section on top of the right side of Mojito only affects the resonant 24 dB low-pass filter.

Reso Controls the resonance of the filter, which is an amplification, or emphasis, of the signal at the cutoff fre-

quency.

Note: If the amount of resonance of a filter is raised high enough, the filter begins oscillating at the cutoff

frequency, thus generating its own waveform. Be careful: this can be loud!

Drive Controls the amount of filter drive from 0 to 100%.

Cutoff Knob Controls the corner, or cutoff, frequency, which is the point above which frequencies are atten-

uated. The range is from 20 Hz to 16 kHz.

The other controls affect the modulation of the cutoff frequency.

Key Controls how much the played note scales the cutoff frequency.

Velo Controls how much the velocity of the played note shifts the cutoff frequency up or down.

Envelope Controls how much the ADSR envelope shifts the cutoff frequency up or down.

LFO Controls the amount of shifting that the filter LFO applies to the cutoff frequency. The LFO can either be

synced to tempo or it can oscillate with an adjustable period.
