SPEAK NOW ! or forever hold your peace

 

Texas Instruments Speak & Spell

 

This is a "staple" in the bender's arrrsanall.  I have given it a try, and I'm still trying. 

I soon went way over the top into chaos territory with just a few controls added.

 

 

Sounds like nauseous dwarves scrubbing their latex SM outfits. 

Ancient voodoo dancers shaking in trance clicking their finger cymbals.

Getting a fit with every new loop held...

 

Ok, I got that out of my system.  Benders need that. The "Blah" .

Especially when you're selling these.  Then you got to have the  "Blah".

I would do the "Blah" if I was going to sell these. I'd be stupid not to. It's a skill.  Like poetry.

That's enough for now

Shut up

Ok, I'll stop the blah now

This thing is probably best when kept simple or get stuck in glitch eternal. Or worse: crash eternal. Mine is in that state at the moment.

Thoughts on bending this thing

- My speak's external voltage input has been modified to "Boss" style  polarity (- on the inner  contact, + on the outside). It was been more of a hassle than I usually have doing this mod for my other stuff.

- I've been intrigued by someone's speak and spells covered with "holografic" metalic foil as a touch contact.   He used to have these on ebay. With colored balls as knobs, and his former plastic monster collection as decorations. I've googled, can't find him anymore. 

Two thin metal sheets in close contact make a capacitor that can be influenced by hand contact. I suppose it works by replacing a clockgenerator capacitor? Is there a double layer  "holografic"? Something to try sometime. Also for other bending targets.

The Electronic Peasant's display ringmodulator

- Another thing I have yet to pull off: electronic peasant style modulation by sending audio through the display. http://www.electronicpeasant.com/projects/ringmod/trmod.html Very interesting.

The display heater is the part to send the audio into. With some bends it can be seen as an orange glowing line and be heard "tingling" inside the display. 

 For the display to maintain its function it needs 2,5V? voltage drop. The + is on the left side, minus is right. I don't recal the exact pins, it's been a while. That's electri-fire: more ideas than he ever can finish.

 Anyway, I guess your signal will need to be biased (added to a plus voltage), fed into the display, modulated along the way, just by the usual display graffics flicker, "beep" signals or other audio, be picked up somewhere from one or more display pins, maybe mixed and amplified.

The display pins use 18 volts am I right?

 The Electronic Peasant uses a condensor microphone against the display, omitting mixer needs.

The 4-pin bus

- Speak&... devices' synth chip recieves its instructions from the cpu in a serial format at a 4-pin bus. To  generate speach in realtime the Speak&... compresses the datastream wherever possible. Bits for unused functions are eliminated, shortening the instruction. So functions do not have a dedicated pin, as  remaining bits are shifted . This way of operation makes them very prone to crashing. 

Being somewhat dyslexic I have had trouble locating the 4 pins that take in the "nibbles".

Highly_liquid has developed a MIDI interface for the Speak&...'s. It is called the MIDISpeak . $49.95 for a kit (not too complicated. I'm gonna get me one!), Assembled: Add $29.95.

When a MIDI note on is sent the MIDISpeak takes 4 of the MIDI message bits to control the speach chip, converting 5 MIDI notes into one 20 bit Speak instruction.

Looking at the installation instructions at  http://highlyliquid.com/  the 4 pin bus can easily be located.

These pins are also the prime targets for conventional "glitch" bends. 

 

God's word creates...

Because of the dataformat, playing the speak&xx's requires (and developes) good timing when engaging a glitch.

Playing these gets me into a very attentive alert state of meditation. They still are learning devices.

As the player/deciple feels the nescessity of harnessing the chaos, the Speak&...'s grab your brain and make it a part of their circuitry by conditioning your reflexes. The sounds created are the reinforcement. But it's playing the game that counts.

That's why electri-fire feels there's No Need for New Bends  

It's all been done. The usual loop,beeps(= several clock and data lines), glitches, reset, restart , pitch, touch. If I find something wild and exciting I'll let you know. But more likely this  freak will ruin another good speak&... in his vain quest for total control.

Again, as stated above, this thing is probably best when kept simple. Electri-fire recommends to stick to the  traditional bends, to follow the masters.

You can make one of these yourself easily.

 

some of the best schematics

 

 To get you started there are some example schematics at oscillateur.com  .

casperelectronics   speak&spell schematic

New site with lots of Speak&... pictures, sounds and schematics at  http://homepage.mac.com/tmckaskle/bending/ .  I wish my site was so informative. Once built my pots are usualy covered with hotglue and too much hassle to recall the values. Ah well....

Also you can try to decipher the more cryptic looking Incantor Tutorial by the Master of Masters, Reed Ghazala.  Have a nice trip through his vast site.  http://www.anti-theory.com/ 

Lots of circuitbending links  including  Speak&... 's   at   http://www.cementimental.com/links.html  . Hey, a link to this page there as well. Thanks dude. Motivates me to update this stuff.

May you all be enlightened by these. They are schematics and/or pinouts/data from Speak&.... chips.

I should give credit to those I got these files from. If  only I remembered where I got them.  One is from http://www.datamath.org/  I'm sure.
