Newbie... first and common questions about CA3084 and uA726

[Denis Lavaud]

Hi,

I subscribed one week ago and as I plan to build
a fully (as most a possible) midified Formant, I
have these questions (asked many times, I suppose):

. Is there any replacement IC for the CA3084 and
uA726 ICs ?! If not, I would be very interested in
any datasheet about these ICs or replacement
solutions ! I read on Rick Jansen's page that he
would use the MAT02 and MAT03 but I do not have
any clue of what it is !


		Thanks a million !

To indroduce myself, I am an Electronical Engineer
but in digital IC design and digital signal
processing. I am supposed to have knowledges in
analog electronics but as I did not practice this
last years...

My project is to build a fully MIDIfied Formant
using microcontrollers (reading analog pot and
switches values and of course MIDI controls and
sending bulk dump and all of this classical stuff)
and controlling digital potentiometers and analog
switches. It seems easy to do, maybe easier than
finding replacement chip to build the analog parts !
This is still the beginning of the project and I
plan to start with the 12dB filter and then,
MIDIfying it. Any comments are welcome !
