        Now that you've tried enough you want to know what all
        the funny elements like <emphasis>Attack</emphasis> or
        <emphasis>LFO</emphasis> mean. I don't need to explain
        it here, look up the terms in a textbook. If you can
        explain the difference between <emphasis>Amplifier</emphasis>
        (Amp) and <emphasis>Voltage Controlled Filter</emphasis>
        (VCF) you can go on looking on the next picture:

 <para>
        As you can see you have access to an Amp and one VCF. This
        is not much from a synthesizer's point of view, but enough if
        your samples are already perfectly synthesized. Gigedit provides
        for 4 tabs, one for each section (Amp/VCF) and one for the
        LFO and the ADSR.

  <para>
   <indexterm>
    <primary>Sample Bank</primary>
   </indexterm>
        First sampler use was just repeating a sound, a drum
        sample, some vocals, maybe short snippets of whole
        orchestrations. This so called <firstterm>Sample Bank</firstterm>
        is a collection of samples, vocals, or sounds that will
        never be stretched along a key range. You simply press
        a key and the sound occurs as it is. So there won't be
        no LFO nor ADSR influence. Regions will range only for one
        key, maybe include the half tone, maybe not. For drum
        maps I personally recommend the <xref linkend="gen_midi_drum"/>.
        If you have different drum sets you may switch easily
        between them without reprogramming your sequencer. Also
        shifting by octaves is easy to change the drums.
