- Wibbly Wave version 0.6
- ╜1996, 1997, 1998 Electronic Cow freeware
-
-
- Wibbly Wave is a sample synthesizer for all Ataris with at least 512k
- of memory, and a 640 x 400 display (or better). It uses a set of
- controls to generate analogue-style 8- or 16-bit *.AVR samples, that
- can then be used in your favourite sample editor or tracker
- program...

- This program is completely free and unrestricted and it may be freely
- copied for all to use, as long as it remains in tact, unaltered, and
- no-one benefits financially from its distribution! By all means,
- include it on your cover-mount disk/CD-ROM, FTP/WWW site, CD-ROM
- compilation or public domain library (the further it goes, the
- better!), but don't expect Electronic Cow to be responsible in any
- way for any loss or damage to your system as a direct or indirect use
- and/or misuse of this program. But hey, it works! The moral is don't
- tamper with it, else it won't. Besides, you wouldn't like us to visit
- your home, and ruin your work, so don't do it to ours please :)

- Instructions:
- -----------------------------------------------------------------
- Wibbly has four pre-set DCO waveforms to choose from: square,
- pulse, sawtooth and triangle/sine, and these influence the timbre of
- the sound created. Square waves and pulse waves produce a sort-of
- metallic sound (the latter sounding much thinner), whilst triangle
- and sawtooth waveforms are better for string sounds (like violins and
- so on...).
-
- In addition to selecting a waveform shape, as from v0.6 you can
- now also choose to add modulation to it! There are two dial controls:
- depth and rate. Depth controls the range of the frequency oscillation
- (up to 48Hz), and rate controls the speed at which the oscillator
- wibbles!
-
- After selecting an oscillator waveform, you need to pick a DCA
- envelope. This setting controls the amplitude shape of the sound, and
- there are three pre-set envelopes to choose from: typical ADSR shape
- (fairly slow attack, sustained period, follwed by a relatively long
- decay), Percussion (fast attack and decay), and Constant (flat
- envelope with a smooth fade). Using Constant allows you to draw-in
- your own wave shape in your sample editor later on. There's now also
- a volume control, and this sets the start amplitude of the DCO before
- the envelope is applied.
-
- Note:
- -----
- To turn the dials, press the left button on the object. Clicking
- on the left side of the dial, decrements the control's value, whilst
- clicking on the right side, increments the value.
-
- Other controls:
- ---------------
- Wibbly Wave now lets you control the pitch of the resultant sound
- much more easily, using an on-screen one octave keyboard. To generate
- a sample with the fundamental frequency equivalent of middle C (circa
- 260Hz), you now just have to press the C key on the keyboard, rather
- than twiddle with a dial! Then you can resynthesize the same sound at
- a different pitch which is ideal for multi-sampling.
-
- Pressing any key on the keyboard will start the sample rendering
- process, which won't take any longer than ten seconds on the slowest
- Ataris, then you can play it back using the play button, or by
- pressing [p] on the Atari keyboard. Sounds can be saved as either
- eight or sixteen-bit AVR samples (use the toggle buttons to set the
- export bit-depth), by pressing the disk icon button. Press the smiley
- button to find out more about this program :)
-
- Note that you must have either an STE/TT or Falcon to playback
- digital audio, as Wibbly uses the hardware present in these machines.
- STFM owners can generate samples but must use a separate player to
- hear them.

- Revision History:
- -----------------
- v0.6: (22nd August 1998)
- fixes to v0.6. Forgot that pre-TOS2.0 machines don't use
- Mxalloc(). Sorry! Fixed memory allocation bug now...
- Fixed small problems in mono and colour resources.
- v0.6:
- complete re-write of the code, resulting in even faster
- wibbles! Now added modulation depth and rate controls to the
- DCO waveform generator. Made triangle wave more soft, so
- it sounds more like a sine wave now! Re-designed the
- interface, and improved Falcon-audio support. Added a
- keyboard for choosing oscillator pitch exactly. Now doesn't
- automatically call the file selector to save the sound (that
- was annoying!).
-
- v0.54:
- fixed a few bugs, and made the whole sample rendering
- process miles faster! Added 16-bit export, and sample
- playback.
-
- v0.4:
- similar controls, but modulation adds noise rather than AM.
- Uses floating point arithmetic and so is quite slow on
- computers without an FPU.No DMA sample playback and only
- 8-bit samples are saved.
