- WTI wavetable file description
- ==============================
-
- 1. Introduction
- ===============
- WTI files describe wavetable information for the Piano/ePiano plugins.
- This information is ini-file format.
-
- Wave data can be raw (just the samples) or riff (a regular wavefile). It should be
- in mono format, although stereo riff files can be loaded (it's just a lot slower).
-
-
-
- 2. Sections
- ===========
- - Info
- - VelocityLayers
- - Parameters
- - Sample0 - SampleN (N = # samples - 1)
-
-
-
- 3. Info section
- ===============
- This section contains general information about the wavetable.
-
- - name : the name of the wavetable (not used yet)
- - shortname : a short name to display to the user (not used yet)
- - samples : the number of samples in the wavetable
- - samplefile : the name of a single wavetable file (optional)
- - filetype : the type of the wave files, raw wave data or a riff wave file
- possible values are : raw & riff
- - path : the (relative) path to add to the filenames
- - author : who created this wavetable
- - samplerate : the samplerate of the waves
- - velocityfactor : a factor by which to multiply the voice envelope at the start of a note (usually not necessary)
- - releasehighnotes : set to "true" to also release the high notes (95-127)
- - isstandard : if 1, this is a wavetable that's included with FL Keys. Don't use this for your own wavetables!
-
-
-
- 4. VelocityLayers section
- =========================
- A wavetable can contain multiple velocity layers. This means that a single note
- is represented by more than one sample, depending on the velocity of the note.
-
- For example, if there are three velocity layers, a note with velocity 20 can use
- one sample, a note with velocity 60 can use another sample and a note with velocity
- 120 is played by a third sample.
-
- In the wavetable data, samples for different velocity layers of the same group of
- notes must follow eachother.
-
- - count : the number of velocity layers
- - 0 .. count-1 : the lowest velocity for this layer, the highest possible velocity is 127
-
-
-
- 5. Parameters section
- =====================
- In this section you can specify initial values for all parameters. These are set when
- the wavetable is loaded.
-
- Parameter values must be in the range 0..1. So valid parameter values are 0.1, 0.453, ...
-
- Each parameter is identified by a number:
-
- 0 : Decay (set to zero for no decay/sustain)
- 1 : Release
- 2 : Hardness
- 3 : Velocity > Hardness
- 4 : Muffle
- 5 : Muffle > Hardness
- 6 : Velocity sensitivity
- 7 : Stereo
- 8 : Tune
- 9 : Detune
- 10 : Stretch
- 11 : Treble
- 12 : Pan/Tremolo
- 13 : LFO Rate
- 14 : Overdrive
-
-
-
- 6. Sample sections
- ==================
- There are as many sample sections as there are samples in the wavetable (see the Info section).
- They are named Sample0, Sample1, ...
- These sections describe some properties of each sample, especially the root note and the
- high note.
- You have to specify all samples for all velocity layers. The samples for the velocity layers for
- a given root and high have to follow eachother.
-
- - name : if the samples are all in separate files, the filename of each sample is specified here.
- You can leave the name of the sample out if it's the same one as for the previous one.
- - root : the lowest note that this sample will be used for
- - high : the high note, usually somewhere in the middle between two root notes
- For the last sample, this has to be more than 127 (999 might be a good idea)
-
- - pos : position of this sample when all samples are in one raw data file
- - end : position of the end of this sample when all samples are in one raw data file
- - loop : the length of the loop, used to determine the looppoint for raw wavefiles (not for riffs)
