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.
