Description       The only machine that can produce ornamented ZX-Spectrum sound without clicks. In addition it has some features that has nothing to do with ZX-Speccy.

What's new in v1.1 ?

1. Slightly bugfixed ;->
2. Totally declicked (Yeah !!! I've done it !!!)
3. Reeled And Skinned ((RedSnapper4ever;-))
4. Antialiased with 24db lopass
5. Attributed (antialiasing on/off, work always on/off)
6. 'About' dlg has been added ;->

By default WorkAlways attribute is 1 (on), because there are some non-correctly
written effects (like DexFiltah with low cutoff and high resonanse) that
calculates nothing if WM is write only. But if you use only correctly written
effects, then set WorkAlways to 0. It'll save your CPU resources in some cases.



List of parameters:

	Command           Description                             

	Waveform:         Master osc. waveform (sine-saw-square-triangle)
	Unison:          _Slave osc. detune                    
	Attack:           \
	Decay:             \
	Sustain:            ADSR-envelope parameters
	SustainLevel:      /
	Release:         _/           
	Arp.length:       Time to play 1 arpeggio note
	Arp.smooth:       Time to morph between arpeggio notes

	Volume:           Max. volume that the sound reaches when attack is complete 
	Ornament:         Ornament number


Details



I have made 34 ornaments, among them the most popular on Speccy are: OctaveAttack, Slideup, PerfectOct, DoubleOct, Kvint-Octave, MinorChord, MajorChord.
This machine is not AY-emulator. It does not support AM and noise (yet), but due to the fact that original AY has
rather flat sound, I have added some non-AY features, such as chorus (to get chorus effect set
Unison to 3..10, or to get phaser effect set it to 1..2), different waveforms (it would be
rather stupid not to add this feature :-)).
And, what about the original Speccy sound, if you care only about it's originality, set Waveform to triangle, Unison = 0, Release = the less the better, ArpLength = 20.000 ms, ArpSmooth = 2.000 ms.

Stuff


If you have found this machine very useful and even wrote a song using it, of course,
I won't mind to hear it. But if you don't feel any nostalgie when you hear triangle wave changing
its pitch 50 times per second and you consider that this machine suxx and I'm a lamer, I would be very pleased
to receive from you some texts on DSP programming, where I could find some formulae to make some cool
stuff.

     I'll be glad to find smth at:
