• 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.

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. Maybe , in next versions I will add some stuff to emulate AY-chip completely. It is not difficult, but I'll have to make a so-called instrument editor (like instrument editor in sound-tracker pro on Speccy) to allow users to set pitch,envelope and noise pitch values for every 20 ms of the instrument. I will make this editor if somebody will tell me how to open my own GUI window instead of BUZZ parameters window (Like in Jeskola mixer). Heeeey, guys !??

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, for example, BP filter. This is my first machine, but if I won't get some formulae, I don't know what to write next. By the way, who knows how to make a machine with a skin ?..
