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. |
