5. User examples
The envelope generated by the ADSR can be used for
most kinds of modulation:
• ADSR - VCA
Modulation of loudness / amplification over time.
• ADSR - VCA for voltage control of any in /
output processes, with the process time control-
led by the A, D, S, and R parameters.
• ADSR - VCF
Modulation of the cut-off frequency produces a
constantly evolving sound spectrum.
• ADSR - VCO (PWM)
Modulation of the pulse width of a VCO produces a
constantly changing timbre.
• ADSR - VCO (FM)
Modulation of the pitch control voltage produces
variation in pitch as a note progresses (and at very
short envelope settings produces variation of tim-
bre).
• ADSR - VCP
Modulation of the phase shift of an A-125 VCP
produces variation in phase shift as a note pro-
gresses. For this function slow settings of A, D and
R parameters should be used.
• ADSR - VCLFO
Control of the frequency of an A-147 VCLFO pro-
duces variation in LFO frequency as a note pro-
gresses. For this function slow settings of A, D and
R parameters should be used.
Examples and further notes can be found in the manu-
als for the individual modules.
