Now that you've tried enough you want to know what all |
5 |
the funny elements like <emphasis>Attack</emphasis> or |
6 |
<emphasis>LFO</emphasis> mean. I don't need to explain |
7 |
it here, look up the terms in a textbook. If you can |
8 |
explain the difference between <emphasis>Amplifier</emphasis> |
9 |
(Amp) and <emphasis>Voltage Controlled Filter</emphasis> |
10 |
(VCF) you can go on looking on the next picture: |

As you can see you have access to an Amp and one VCF. This |
21 |
is not much from a synthesizer's point of view, but enough if |
22 |
your samples are already perfectly synthesized. Gigedit provides |
23 |
for 4 tabs, one for each section (Amp/VCF) and one for the |
24 |
LFO and the ADSR. |

First sampler use was just repeating a sound, a drum |
66 |
sample, some vocals, maybe short snippets of whole |
67 |
orchestrations. This so called <firstterm>Sample Bank</firstterm> |
68 |
is a collection of samples, vocals, or sounds that will |
69 |
never be stretched along a key range. You simply press |
70 |
a key and the sound occurs as it is. So there won't be |
71 |
no LFO nor ADSR influence. Regions will range only for one |
72 |
key, maybe include the half tone, maybe not. For drum |
73 |
maps I personally recommend the <xref linkend="gen_midi_drum"/>. |
74 |
If you have different drum sets you may switch easily |
75 |
between them without reprogramming your sequencer. Also |
76 |
shifting by octaves is easy to change the drums. |
