Operation Manual

4.8 Output Effect Stage 61
if the sync signal comes from an external source or from the internal clock of the module. When
the Tassman is used as a plug-in in a host sequencer and the ext source is chosen, the clock signal
will be that sent by the host sequencer while in standalone mode the clock will be the one received
on the MIDI channel selected in the Player toolbar. When the int source is chosen, the clock is
adjusted in the green tempo display in beats per minute. To change the tempo, click-hold on the
display and drag up or down or use the up and down arrows of the computer keyboard after clicking
on the display. The play and stop buttons are used to start or stop Sequencer modules in your patch
that have been connected to a Master Sync Input module while the reset button is used to send a
reset signal.
The Delay module
This module is a standard ping pong delay and is based on two delay lines. The time display sets
the length of the lines. When the sync button is pressed, the sync signal from the Sync module of
the output stage is used to determine the length of the delay line which is adjusted to fit the number
of steps appearing in the display, four steps representing a quarter note. The feedback knob is used
to adjust the amount of signal re-injected from the output of a line into the other one while the cutoff
knob controls the cutoff frequency of the low-pass filter applied to the signal in each line. The pan
knob is used to adjust the panning of the echoes between the left and right position. Finally the mix
knob controls the relative amount of “dry” and “wet” signal in the output signal. For more details
on the algorithm implemented in this module, please refer to the Sync Ping Pong Delay module
description in Section 6.86.
The Reverb module
This Reverberator module is the same as that included in the module library and described in more
details in Section 6.70. The size button is used to choose the size of the room from small (1) to large
hall (4). The decay knob controls the reverberation time of the room (note that the range of this
knob depends on the setting of the size of the room). The diffusion knob is used to adjust the time
density of the echoes which is related to the geometrical complexity of the room from simple (left)
to very complex (right). The low damp and high damp knobs control the relative decay time of the
room in the low and high frequencies respectively, a characteristic associated with the absorption
of the wall of a room. Turning these knobs to the right decreases the decay time of the low/high
frequencies. Finally the mix knob is used to set the relative amount of “dry” and “wet” signal which
is related to the proximity of the sound source.
The Output module
This is where the adjustments of the overall level is made. The best dynamic range is obtained
when the level meters are around 0 dB for loud sounds.
