[CZsynth] Re: VZ8m Manual & FM Bit resolutions

2001-06-11 by Summa

Hi Todd,

>I think the manual has about 80 pages of so (can't remember off 

I can imagine how much work it is to scan 80 pages, I already did this with
the nearly 70 pages of the german CZ-1 manual...

>the top of my head). I assume you're not in the United States- so 
>I couldn't just mail it to you (I'm willing to do that if you're in the

I don't know what's the price for shipping the manual... so if it isn't too
much I would pay for the transport...

Since I have a VZ-1 not the VZ8m so I think in my case those pages would be
the important parts of that manual...

When you're ready please add the URL to the bookmarks of the list and post
it into the list...

This is strange, since DX7, DX9(4OP)and  DX21 (4OP) etc. should be 10 Bit
too I at least remember the DX9 to be quite "noisy"... anyway there seems to
be lots of different informations about this... 
Also my MT32 with bad converter sounds more crispy then the D110 with better
converters... sometimes lower sampling rates and lower bitrate can create
wanted sound quality... think of the PPG with it's 12 Bit converers and 8
Bit wavetables... 
It's also known that for instance the 90s SY77/99 synth creates less alising
and sound less agressive then the older Yamaha FM synths... 
Other then that it's the TX81z probably has, as all 4OP synths, a higher
modulation index as the 6Op (or the 8OP FS1R) ones so it might be worth a
try to couple some modulators to recreate that behaviour on the VZ-1...

I haven't even noticed it...
