Int Via Vel
The upper arrow controls the upper modulation intensity setting for the modulation
envelope, if you strike a key with the hardest fortissimo (velocity = 127). The lower
arrow controls the lower modulation intensity setting for the modulation envelope, if
you strike a key with the softest pianissimo (Velocity = 1). The green bar between the
arrows displays the impact of velocity sensitivity on the (intensity of the) modulation
envelope. You can simultaneously adjust the modulation range and intensity by
grabbing the bar and moving both arrows at once. Note that as you do so, they retain
their relative distance from one another.
Mod Envelope
The modulation envelope itself only has one parameter. You can set a percussive type
of decay envelope (low values), or attack type envelopes (high values). A full setting of
the modulation envelope delivers a constant, full level. This is useful if you want a
parameter to be modulated solely by velocity: select a modulation destination, (LFO
Amplitude, for example), set the modulation envelope to full, and adjust Int via Vel as
needed, in order to obtain a velocity sensitive, yet non time-variable amount of LFO
Amplitude modulation.
ADSR
The ADSR envelope affects the filter (ADSR via Vel) and the amplifier (if set to ADSR).
The parameters are attack time (A), decay time (D), sustain level (S) and release time (R).
If you’re unfamiliar with these parameters: set the amplifier to ADSR, the Cutoff to a low
value, Resonance to a high value, and move both of the “ADSR via Vel” arrows upwards,
in order to check out what these parameters do.
Tune
Tune sets the pitch of the ES1.
Analog
Analog slightly alters the pitch of each note, and the cutoff frequency, in a random
manner. Similar to polyphonic analog synthesizers, Analog values higher than zero
allow the oscillators of all triggered voices to cycle freely. Note that if Analog is set to a
value of zero, the oscillator cycle start points of all triggered voices are synchronized.
This may be useful for percussive sounds, when looking to achieve a sharper attack
characteristic. For a warm, analog type of sound, the Analog-Parameter should be set to
higher values, thereby allowing subtle variations for each triggered voice.
Bender Range
Bender Range selects the sensitivity of the pitch bender in semitones.
Out Level
Out Level is the master volume control for the ES1 synthesizer.
