Model 291e Triple Morphing Filter
291090919
The 291e consists of three voltage controlled filters which can be operated
independently or in parallel.
The amplitude, center frequency, and bandwidth of each filter may be
independently voltage controlled. Each may be modulated with externally
applied signals.
The morphing capability might be described as moving through a series of
snapshots of the filter, with each snapshot consisting of a complete
description of the filter parameters, and each parameter continuously varying
between snapshots. Morphing is accomplished with an applied voltage, or
alternatively can be initiated with a pulse, with each stage time independently
set. From one to eight stages may be employed.
To edit a stage, select a desired stage with the red edit select switch. A red
LED indicates the selected stage, and the green LED in the ninth position
signals the play mode. The green switch toggles the play mode. Note that
editing can be performed while in the play mode, allowing you to perceive the
dynamic effect of changing parameters.
The central switch selects one of the three individual filters (nodes) for editing.
Use the rotary encoders to adjust the values for amplitude, bandwidth, and
frequency for each node. Note that amplitude affects only the summed output.
These three parameters may be modulated by signals applied to the
modulation inputs. Use the switch to select amongst 7 combinations of
modulation types, and the rotary encoder to adjust the modulation intensity.
The LCD will display the exact levels as well as the modulation amount:
