Hi Richard,

There is some flexibility in the software. If you drop a single cycle
wav file with say 400 samples onto the app it will downsample the
waveform to be 128 samples automatically. The results are not
hi-fidelity as I only use a simple algorithm to do that, however it's
still useable. When this downsampling has taken place you'll see a
little red dot or asterisk on the waveform display.

For creating single cycle waveforms I've found a really app to use on
Windows is the simple waveform editor called EZ-Editor :

http://www.ez-editor.com/

... on their site you'll see there is a feature called Formula
Editing. With that you can create a single wave file with a specified
number of samples based on a formula you enter.

That editor was written by the guys at Zero-X and some of their other
products such as BeatCreator have the same feature too. In Beatcreator
the feature is called Formula Wave Shaper.

What I have also had some success with is taking a bunch of single
cycle waveforms (I found a bunch someone made from the digital waves
on the Access Virus) and using SoundForge's batch processing mode to
downsample them all to 128 samples.

Finally, IIRC, in the Windows version of the utility, once you've
dropped a wave file on the application you can double click the
waveform (the black and purple bit) and a simple waveform editor comes
up. This is not an official feature, just something I was messing
with. You can draw with the mouse, normalize the waveform, apply a low
filter (to smooth the waveform) and there is an option called
Additive. If you hit Clear and then draw a few little columns on the
waveform window with the mouse representing andthen click Additive it
will create a waveform for you. The position of each column is the
frequency of the harmonic and the height of each column represents the
amount of the fundamental. As I say ... this was just me messing ...
its by no means a powerful waveform creation tool.

For Mac users ... check out Turbo Synth ... a now defunct Digidesign
product I saw mentioned in a mag recently. Google for this "turbosynth
sitx" to find a copy of it. It's Mac OS 9 only, but will run on Mac OS
X in classic mode.
