not have to change this. In case you want to assign a new controller to the knob, specify the
number here.
• You can also assign a different MIDI channel to the controller in the MIDI channel textbox.
By default this value will be set to channel 1.
• There are two other parameters one can adjust: the Minimum Value and Maximum Value
of the controller, which are used to limit the range of MIDI controllers. The Minimum Value
field determines the position on the Tassman controller to which corresponds the minimum
value sent by the MIDI controller; the Maximum value determines the position to which
corresponds the maximum value sent by the MIDI controller. A value of 0 corresponds to
the Tassman Player controller minimum position (left position for a knob) and a value of 1
to the Tassman controller maximum position (right position for a knob). Set the Maximum
value parameter to 0.75.
• Click OK and the link appears in the list of controllers linked to this VCO module.
• Click OK again to confirm the change and to leave the edition window.
Playing
While you are playing, move the modulation wheel of the keyboard to control the amount of mod-
ulation of the LFO on the VCO. As you move the wheel, observe that the mod2 knob also moves
on the screen. Remember that any knob of the interface on the Tassman Player can be linked to any
controller. You can, furthermore, link as many interface controls as you want and you can move
them simultaneously.
Step 6: Creating a polyphonic instrument
Description
So far we have been using a monophonic keyboard, which means that we can play melodies but not
chords. The Polykey or Polyvkey modules are used to create polyphonic instruments. Creating a
polyphonic patch involves three steps. First you have to connect the polyphonic keyboard module
to the other modules of the synth. You then need to connect the output of your polyphonic patch
to a Polymixer module. Finally, you have to set the number of voices. The number of voices is set
at construction time and the number of voices you will be able to run on your computer without
loosing real time depends on both the power of your computer and the complexity of the instrument
you are playing.
Construction
• Select and delete the Keyboard module in the construction area.
