Casio CZ/ VZ/ FZ - Pro Series

Hi, 

I have some of them including D-70. I like D-70's sound quality very 
much, and to me it's even better than later models like SuperJV/SuperJD.
I agree there's not much information about D-70's DLM, and you'll surely 
be curious about it, Scott. I haven't explored DLM much yet. It's difficult 
to use DLM effectively, but it provides new possibilities still today.

Below are the main differences between D-series.

D-50/550
PCM ROM: 128KB
Multiple LFO modulation incl. PWM
FX: Reverb, Chorus*2 and EQ*2

D-5/10/20/110
PCM ROM: 256KB
LFO only for vibrato
FX: Short delay/Reverb
Multi-timbral, no aftertouch

MT-32
D110 with less ROM.

D-70
Expanded version of U-20; a rompler with multimode filter and DLM.
PCM ROM: not clear but maybe between 1 or 2MB, expandable with cards

MV-30
D-70 without DLM and patch layer.

D-70's DLM (Differential Loop Modulation) is like relooping a sample. 
You can set the start point and the length parameter. No LFO modulation -
 it's different from Transwave.
When you change a sample's loop settings in your sampler, it creates 
loop noise. When the loop length is very short, it can be a new oscillator 
waveform.
DLM does more by expanding the loop segment when relooping. It sounds 
like a short-looped pulsy waveform, a failed sample-loop, or a noisy 
granular sound. Sometimes it sounds like what you hear when your synth 
is half-broken.

Best,
Sealed
