Operation Manual

6.3 After Touch 70
Typical Use
The ADSR is Typically used for generating amplitude envelopes through a VCA, or spectral en-
velopes by modulating the frequency of the filter modules. An ADSR can also be used to obtain
an auto wah wah effect as shown in Figure 95 under Vbandpass2.

6.3 After Touch
The After Touch module is used to send the after touch control from a MIDI keyboard. It has one
output, the after touch signal. It outputs a value ranging between 0 and 1 volt. This module has no
front panel.
Typical Use
The After Touch module can be used to control modulation inputs on a VCO or a VCF.
6.4 And
The And module performs an AND logic operation. The one output of this module is either 1
(true) or 0 (false) depending on the values sent to the two inputs. To deliver 1 at the output, the two
inputs must receive a value of 1 otherwise the output will deliver a value of 0. This module has no
front panel. The following table shows the output value depending on the values in the two inputs.
Input signals are considered False (0) when smaller than 0.1 Volts and True (1) when greater
than 0.1 Volts.
