Casio CZ/ VZ/ FZ - Pro Series

Hello, 

Thank you for your response and I'm glad to talk about and investigate 
my HT and CZ.

I suspect HT uses PD rather than PCM because...

1. There is no accoustic samples, or accoustic simulating short loops 
(like Korg DW-8000 and Ensoniq ESQ-1, etc...). All I hear is familiar 
CZ brass and EP, though I can't exclude entirely the possibility that 
it might be sampled CZ sounds.

2. Some 'waveforms' has a short transient decay. The decay time doesn't 
vary when played at different pitch.

If anyone is interested, I will upload some samples to our files section 
or other places.


As for SD synthesizer models, I suspect they all share the same architecture, 
but HT-6000 is a bit improved version.

HZ-600: First introduced as a synth.
HT-3000/3500/700: Programmable auto accompaniment and a drum machine 
added.
HT-6000: Velocity sense added.

A catalog discription says that HT-6000 has 'Line edit' function. What 
it means is uncertain, but I hope it might be an ability to edit its 
two DCO's individually. 10 analog-like waveforms are printed on the panel 
of HT-6000, which reminds me of my CZ-1's panel. Maybe HT-6000 is the 
most editable in the SD synth line.


As you advised me, I can create similar sounds, putting CZ output into 
a filter. I may someday get an analog synth with an external input.


Best,

Sealed
