Speak and %ksjfd %# K K K K !!! [Sep. 3rd, 2008|12:11 am]

Bending the Speak and Math is a lot more satisfying than the Speak and Spell was, for a number of reasons:

1. Slightly better mechanical proficiency, with practice.
2. Found a better bend chart. The Reed Ghazala diagram is for a completely different revision of the board.
3. Improved ghetto soldering skills.
4. Better ideas about how to fit the controls into the case. On the Speak&Spell I couldn't work out where a full size potentiometer would fit so I sacrificed the battery compartment. This time I just boogered out part of the case to make room up by the handle.
5. Doubling up momentary switches with toggles. So you can trigger the loop toggle, then flip the switch to hang onto it.
6. Better -- no crash -- pitch control. Ended up hooking in-line a big-ass 47k resistor, but hey if I ever need to pass 200 volts down that path, I'm set.
7. Overall, more awesome bent madness with this model. The proof is in the sound. Plus the Speak and Math puts something resembling line level out the earphone jack; my speak and spell I had to use my Putney CV cable, which has a 10K resistor in line.

I concur.

Re: I concur.

Yeah actually when I was looking around for bend schematics (the one in the Reed Ghazala book is for a completely different circuit board.) your Speak and Math came up pretty close to the top in Google.

The craziest one is the CasperElectronics bend, which unfortunately is a pretty low res image:

Re: I concur.

This casper page is actually what I used when bending my S&M, though the graphic above has been totally updated since then. I had to find a reasonable LED reference point on my own. Initially, I had it across the speaker and a +v line, which resulted in a cool rhythmic clicking in the audio, but that's not really something you want all the time, so I settled on a data line/+V.

photos???

i could never understand why people want to bend speak&*s. isn't that what effects pedals are for?

personally, i like the voice synth best left alone. wish i had one!

Photos? not much to see. a bunch of wires in a rats nest.

Listen to the sound sample and tell me how to do that with a pedal.

yes, i understand. but also - why do you WANT to do that? ;)

OK, apparently I like the stuff everyone else can't stand. Do you mind if I sample this? I want to mash it up with some Dawn Upshaw and that David Lee Roth isolated vocal track.
