Howdy - Just to resurrect this thread to say how much I love this thing. Instant didgeridoo! (among other wonderful phonetic surprises) - Had it for six months and it's a part of nearly everything I do in 5U.

I have two questions I haven't been able to figure out - Can anyone answer this?

1) What does the ACTIVE CV input do, exactly? What would a use case be, and what kind of CV to feed it? - Maybe this answer is in John's wonderful demo but I'm not seeing it. (Too distracted by the awesome sounds perhaps)

2) I know phoneme 64 is supposed to be the Daisy demo but I can't figure out how to make it play. I dial to 64 and it says STP but is silent. Same for 63, which is also silent but says PA1 - Do either of those play Daisy? Would love to know.

Danke, all - E

It's not a CV input, it's a gate output. See 7:30 of my video 8-)

:hmm: Did you fire a gate into it or press the Hal 9000 button?


As a side note, the Scat-Talker is also great for sound design and creating all sorts of atmospheric effects. In a recent piece of mine I used the Scat-Talker throughout, pitched way down and slowly sequenced to create that sort of swirling background noise/texture. It's subtle most of the time. I mentioned I used a gong in the piece and people may assume that is what they are hearing throughout but the gong only happens at the very end.

Beautiful piece John! :nana: :hail:

As for the Daisy demo - Early modules had it as the last Phoneme, but a couple of people complained that when doing things like random sample & hold phonemes, it was hard to prevent the demo from firing.

So in later firmware revisions, I moved it to the power-up sequence. To get to it, hold down the button while powering up the synth. This will take you to Calibration and Demo mode. You can then select the demo with the phoneme pot and press the button. Calibration stuff helps when I'm setting the 1V/Oct response at the factory.

Ah, JOHN: As usual, Muffwiggler should pay a retainer and a per diem for your amazing quick replies, man! A gate out! That makes sense, but I'll want to watch your video more closely to see how that's applicable. I'll check 7:30 of your vid, thanks for the :help: !!!

(watches) - ah,amazing! that's perfect for envelopes and VCAs! Still not perfectly understanding how it's not a through-output of the gate input. When does the gate fire out of the Active, exactly? And how is that different then when the Gate is inputted?

(thinking) So is this what you mean - that if you click GATE to trigger a voice, the phoneme changes, but every time the phoneme loops, it outputs an Active gate of the voice initiating? That's...cool! Is that what you're sayin? Either way knowing it's an OUTPUT now will be fun to just randomly patch into something see where it goes regardless of full understanding.

Ah-ha!!! I will try this! Daisy will be mine!

Thanks man, your module is amazing. Firmware revisions, eh! Curious about distinctions of other versions, I suppose. There's only 75 of these things, I think I read, right?

Beautiful work on this, thanks so much for bringing it to the planet.

(Thanks again for the answer and demo, John, you rock)

I checked out "The Bureau". Wonderfully creative stuff and links. That made my day and I shared on FB.

The ACTIVE output reflects the actual Votrax SC-01 chip's phoneme length. Once the Scat-Talker's Gate is fired, the Scat brings the ACTIVE output high for as long as the SC-01 chip thinks it appropriate for that particular phoneme. Each phoneme length should be different.

For instance, you had mentioned earlier why STP & PA?. Each of the SC-01's phonemes has a "default" length that it will play the phoneme. This was apparently done with research into how long it takes to make each phoneme is the English language. Using that output from the chip, a host computer could more easily concatenate phonemes to build words, without having to create a separate "look-up table" outside the chip.

Doug: Thank you for the explanation and I'm thrilled to hear you enjoyed The Bureau! And thank you for the FB post! (My regard for your stuff is off the charts btw) - You'll hear Scat Talker in the second act of music (After the 1:00pm mark, or so - Story's at 11:30 presently)

That makes perfect sense about the Active port. Even makes the module more exciting, Yeahaww!

Have a great evening, thank you both. - Ethan

The Scat-Talker has been sold out for a couple of months now, but here's the good news...

I found a few more SC-01 chips, so I'll be making a FINAL round of 7 of these. The price will have to increase from $349 to $399 because of the small quantities I have to order from my vendors.

Don't hold me to dates here, but the PCBs and all parts are already in-house and the panels should be here by the end of the week. So I'll guess availability by the end of June.

Now you have me wondering if I should get a second one....

Yeah, totally - you should do that. A second one might be totally interesting and weird, especially in duophonic mode, a two-voice Scat!

Wow - outstanding fortunate news for anyone without one of these, Doug.

Since you're here, one tech question: I've found that putting noise into the 1v/oct slot totally transforms the voice of the module into wonderfully sounding chalky talking. (just a texture is applied to the output that's really pleasing) - Just wanted to be sure that wouldn't affect the chip or any connections in any way that's negative. Don't believe so, but I know nothing about the way these chips work with CV and I'd like to keep it healthy and working for years.

Specifically this is the noise output of an RF Nomad into the 1v/oct input of the Scat Talker.

Happy to hear of seven more units! Interested in the proposed reissue of the JJP SampleCorder, too.

That's a great idea Ethan! I seriously doubt it will do any harm to the module. Patch away and keep coming up with (and sharing) those ideas!

I received a used Scat Talker with firmware 1.3 yesterday.

I just had about an hour of fun with it. Very well built and handy to use even without a manual (is there one available?).

I will, once the summer is gone, use my good old EEH DS 500 digital sequencer with CV out to construct some words.

I have a weekly comics/audio series going on Boing Boing right now where part of the post features a review of equipment I really love.

This week features Doug's Scat Talker with numerous sound file examples of its use in The Bureau (and an embed of John's excellent demo)

Question:
Is there a way to adjust the phoneme CV in, so that a 1/12th V is changing it the phoneme by 1 number?
On my unit, it takes about 4.5 V from phoneme #1 to #64.
If it would be scalled one phoneme per key, it would be 63 steps of 1/12 V = 5.25V = 5 ocatves plus 3 half notes.

Sorry, there's no scaling adjustment for that but you can use a passive attenuator.

Thanks Doug.
I may add a little trimmer to avoid patching and adjusting a passive attenuator every time I use a scalled CV.
I got a friend with a licence to solder :-)

This module is a great addition to my system.
