Don't you introduce some nonlinearity by using vactrols? I guess with a vactrol, all discussion about a few millivolts of DAC INL would be unneccessary.
What I did on my SSM2044 module, that VCF is quite touchy when it comes to steppy CV (regardless of glitch noise issues, the output of a 12 bit DAC has sharp edges - the DAC is fast, the update rate on e.g. MBSID V2 is only every 2 ms, so there are hard jumps in the CV), I added a simple low pass filter on the CV input to smoothe the voltage a bit.
S
these linearity errors are code dependent, hence, if you notice it (?) try giving it an offset in digital realm and compensate for it in analog realm.

...Thorsten, Im lacking the words ... got to ... click... beeer....

can you tell me a good software LFO? I can't find one that does what i want ,interpolates between waveforms... OR curve fitting between given points :P
-
smooth, no customs here either! Thank you very much for the effort ! :)
Fussylizard, give a tought : http://www.synthtech.com/motm440.html
everything is vc controlled so you can just leave the pots out . PCB is 40 usd, worth it , as nothing comes close?

Ah, ah... Whats wrong about this is that an average guitarist knows more about harmonics than your average techno dj, hence, the FM synth is in better hands :P

a discrete ssm2040 ...
http://www.synthtech.com/motm440.html
pcb sells for 40usd, also the components are expensive (ok maybe not so , non-ROHS lm394 is cheap ). I ve yet to hear te results... will buy this year.
-
if it wont work, I would definately try getting a MOTM 440 PCB .
-
no problem on my behalf either, im 99% sure it will slip thru.
Now if i wanted to build an MBFM too... Thats not so sure,but im looking for tx802 anyway.

nah, I used to edit the html, and fax a screenshot (fax!! no email again lol). Besides, "I heard" that 50 usd upper limit is a local invention (.hu) as it used to be 150 in other eu countries.
-
awaiting invoice....and yes, about shipping INT, i would like mine to be specified as 50 usd including shipping , this means the LCD's should worth around 15-20 usd overall. Im a cheapskate, besides customs procedure takes +1.5 weeks as they first send me a mail. (Yes , mail, no email. )
-
you re right :(
I don see how i was mistaken , as that ym2604 has the 16bit parallel out. HAHAHA. Nevermind, maybe I was one step ahead of myself and someone is about to release an FPGA core I can use with 16bit out that 'd be cool ...
-
ok guys, I have a few dozen PCM54 da chips Im willing to give away for participants if we get this rolling, also an idea about a novel output stage.
-
some internal yamaha doc leaked a while ago:
also notice the ym2612 is used inside the yamaha dx7 II in conjuction with a 16bit linear PCM dac, so if the YM chip can be bought theres nothing to stop us ? I checked chinese site, stock appears to be low but present. Guess they gladly source it and we dont have to fear fakes as oef yet.
Looky:
I will gladly support such efforts!!!

very innovative company!
u mean, boutique ? Agree

hi , you have to use relays or you get crosstalk. The best DMOS FET switch is like -107 crosstalk, thats clearly enough for a lot of things tho : ))
Several sellers are in bizness @ ebay for input selector, what else you wan in hifi?
These crosspoint switches have builtin opamps i dont lik those either.

nah , just wait until I share these hardcore FM sega genesis soundtracks straight outta Nippon

I love his Ym2612 core.

Does studying the math of FM synthesis do much good anyway?
Listen to the vibes man....the vibes....

is there a better topic for this? I'd prefer the integrated LDR (Fairchild) version though.

hi, can 't you arrange something with the folk over there at prodigy pro ? There were at least 2-3 europeans involved with case stuff.
