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

As you can see you have access to an Amp and one VCO. 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/ VCO) and one for the LFO and the ADSR.

Sample Bank First sampler use was just repeating a sound, a drum sample, some vocals, maybe short snippets of whole orchestrations. This so called Sample Bank 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 . 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.
