you will hear a kind of hi-hat sound. With the VCO set to the noise waveform, you will not hear
any change in the pitch while playing the keyboard. This is because noise has no pitch.

First, note that the mod1 knob on the VCO is turned so that the keyboard has no effect on the pitch
change. The pitch change is caused by the keyboard modulation on the filter VCO (mod2 knob).
When the resonance on the filter is very high, the cutoff frequency is boosted and the cutoff itself
is modulated by the keyboard (mod2 knob) so that it follows the pitch of the keyboard.

In this sound, you can hear the fifth of any note you play. This is achieved by adjusting the cutoff
on the Vlowpass2 on the third harmonic of the fundamental (interval of a twelfth) and enhancing
it by using a high resonance. The cutoff frequency of the filter is adjusted with the Keyboard pitch
output so that the effect is transposed throughout the whole range of the keyboard. With the noise
wave on the VCO, you can still hear the isolated harmonic and play melodies.
2.3 Tutorial 3 Using a Sequencer
In the last tutorial we played the synthesizer we constructed with a keyboard. It is possible, how-
ever, to use a sequencer instead. A Sequencer is a module that records note patterns and then plays
them automatically. In this tutorial, we will use the same synth again as this will give us the oppor-
tunity to create a sub-patch and to include it in the Tassman module library. There are combinations
of modules that you will be using often or even some instruments that you will want to use as a
basis for constructing other instruments. To save you the trouble of connecting everything again,
the Tassman allows you to save patches and include them in the module library. They will appear
in the Browser, in the Sub-Patches section, like any other elementary module (such as a LFO or
a VCO) and you can use them in any other assembly you make. Note that you can move them in
another folder if you want. There is really no limit to the number of modules you can add! This
feature enables you to take full advantage of the modular architecture of the Tassman. You can
expand your module library as you use the Tassman or exchange modules easily with other users.
Do not forget to have a look regularly at our web site for new sub-patches to download.
In this tutorial you will learn to:
• Create a sub-patch.
• Use a sub-patch from the Browser.
• Use a sequencer.
