Sure, I'll try to get to it.Hi Led
Can you post images of your vocoder?
Very clever changes!On my version I tried to simplify the wiring. I also added the freeze function with a push button in addition to the pedal.
Finally I redid the test oscillator card so as to easily use it for calibration.
I have several ideas for modifying it as well. I'll check my notes and get back here with more details if interested.
I also have some ideas for the front panel and like the EMS Vocoder 3000 layout a lot.
Come to think of it, if I recall correctly, the ETI vocoder was designed by someone who worked at EMS. But of course at a much lower cost and with less features. Still, I consider the ETI as a quite advanced vocoder for most musicians.

I agree! With my Roland VP-330 I would say that at least 50% of the sound was due to its chorus ensemble effect.'ve never had a Roland vocoder apart from the VP-03. but the vocoder function is limited to internal sound.
I made the Okita vocoder which seems to be a clone of the SVC350 but with only 10 bands. It is missing the effect part which seems to me to be a chorus applied to the mic input.
This is undoubtedly what gives the particular sound of the Roland vocoder.
According to a previous forum thread where I asked about the VP-330 ensemble effect I was told it's best replicated with the Oakley sound SRE-330 (enhanced stereo ensemble and chorus module) which is based on 4x BBD chips. Taking up a 1U rack space it appears to be quite a big project, so I'm not sure I want to do that after all (I was hoping for a small pedal sized PCB instead, so it was a bit surprising).
I might add another chorus/ensemble hardware effect inside the ETI vocoder's enclosure though, or maybe just leave the vocoder as it is originally and instead rely on DAW plugins (I already have the XILS Chor'X which has a VP-330 mode). By the way, I also have the XILS V+ vocoder plugin, which is a software version of the VP-330. It's nice to have until I get the ETI hardware vocoder working Image may be NSFW.

Oh, there's also the (free!) TAL Vocoder which is a plugin recreation of the Roland SVC-350, but also includes a built-in excitation.
Cool! So it's perhaps a more "cold" and "thin" sounding vocoder than the ones by Roland which are widely considered "warm" and "musical" by many musicians?The ETI vocoder with its internal oscillator is more like a Kraftwerk-style robot voice effect.
But by using a Juno 60 or 106 with chorus effects as inputs we should get closer to the sound of the Roland.
If you feed a simple saw-wave into the ETI, and do the same with the Okita vocoder, do they sound similar (perhaps with some adjustments of the filter frequency controls)?
Personally I like both the "cold/thin" Krafwerk style robot voice sound as well as the "warm/fat" Roland sound -each have their use.
"Mr. Roboto" by Styx (1983) is a great example of the "fat" sounding vocoder sound I'm talking about (around 40 seconds from the start). I've heard they used a VP-330 for that track, but don't know for sure (perhaps someone reading knows more -maybe pointing to an interview or something).
