Wibbly Wave v0.4 1996 Electronic Cow

Wibbly Wave is a sample synthesiser. It uses a set of controls to generate 
analogue-style 8-bit *.AVR samples, that can then be used in your favourite 
sample editor or tracker program... 
This software is freeware, but it would be great if you decided to send me a 
note to say that you've used it (and liked it ?!). As freeware, this program 
can be freely distributed, but please don't:
* Feature this program on any compilations or cover-mounts without
first writing to the author at the address below
* Edit and amend the program in any way.
* Steal any bits from it...

System Requirements:
Any Atari with 512k or more, running any TOS, including multi-tasking 
systems like MagiC etc., and a resolution of 640 x 400 (or higher). The 
Falcon version uses the 3D AES extensions and so really needs 16 colours to 
work properly. Wibbly will also use a maths co-processor if fitted, although 
one isn't necessary for normal operation.

Nasty disclaimer...
Whilst the program has been tested on a number of Ataris (Mega 
STe, STacy, Falcon, and STFM), I cannot be held responsible if Wibbly Wave 
causes you any loss, consequential or otherwise, to your 
system. Having said that (nasty legal stuff), I have tested it with lots 
of software and hardware: Blow Up, T28e accelerator, MagiC, NVDI, 
Geneva, Let 'em Fly, and Maus Window, and it works fine... 

Instructions:
Wibbly has four pre-set DCO waveforms to choose from: square, pulse, 
sawtooth and triangle, 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...).
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: String (slow attack and 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.
Finally, there are two dials for additional synthesising: frequency and 
modulation. Frequency controls the preceived pitch of the sound, and ranges 
from 200Hz to 2KHz, whilst modulation controls the amount of noise 
modulation (amplitude wibbling...) the waveform is subjected to. The more 
modulation you set, the noisier the sound, and consequently, the less like the 
original waveform set in the DCO. 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.
Pressing the Export button sets the program about calculating the sound. It 
can take up to around thirty seconds on a slow Atari (it depends on what 
waveform is selected; square and pulse are generated faster), but a progress 
bar at the bottom of the box keeps you up-to-date. When it's finished, the 
file selector is called, allowing you to save your sample. You can then quit 
and load the sample into your editor, or experiment some more...

Comments, suggestions and remuneration are more than welcome... A DSP 
version for the Falcon, and sample editing and playback within the program 
are some of the future plans.
