Roland TR-505B with 6-Position Swich Matrix * Circuit-Bent*

Let's bee friends... and it's got a picture of a bee on it!

- Ralph Wiggum

The TR-505 seems to be becoming my specialty.

This one features:

4 6-position Rotary-Switch Matrix

8 Mute switches for individual drums

1 Audio input for Hi-Hat Channel

1 Audio input for Tom Channel

Rotary Switches are FAR better to bend with than RCA patch-bays. I'll do a tutorial on how to do this very soon. Probably when I get stuck into my Mega Drive II. Not only does it look neater, but its possible to write down or remember your favorite settings

I'll post some audio of the Weird Sound Generator in the Tom Input, Atari Punk Console in the Hi-Hat Input. Then things get really awesome!

Speak and Spell *Circuit-Bent* with optoVibrato Switch

Say it! Bitch!!!

This is a relatively modest bend for a Speak and Spell, but it is extremely stable.

Features:

1 Momentary Loop switch (with 2 directions)

4 Tone Buttons

1 Pitchbend Pot

1 optoVibrato switch

The optoVibrato switch is a cool addition. I simply found a point on the chip that sends data whenever a word is said, connected an LED/LDR combination to it, and sealed it inside the unit. The LED flickers with the data, the LDR is strapped across the PitchBend Pot.

Works great ; }

MIDI could be nice.... another job for Highly Liquid?

Speak and Math *Circuit-Bent*

Solve it! Greater than less than...

The Speak and Math has a far superior tone compared to the Speak and Spell.

This one has:

2 glitch switches

2 loop switches

1 tone button with 3 tone switches

1 pitchbend pot

3 pitchbend body contacts

1 hard reset button

Sometimes it makes the coolest underwater bubbly beats...

... sometimes it doesn't.

Ibanez Auto Filter Pedal *Circuit-Bent*

Woop-Bzzz-Woop-Itty-Bzzz....

Some people think this thing looks cool... personally I've gone off using RCA patch-bays. Too messy, and hard to pull out. However it's a cheap and quick option.

But aside from how it looks, it sounds fantastic! No longer real good for guitar, but on something dynamic and repetitive like a drum machine, it kicks butt!

The 3 pots on the right attach to the internal trim-pots for Envelope Attack, Envelope Release, and Filter Cutoff (or Envelope Depth. Whatever way you want to look at it.)

And the Patch-bay creates all sorts of self-oscillating crazy-good wrongness!

Bendy-bendy Sine and Ring-Mod tones, plus dynamically controlled distortions hisses and glitches.

I'll have to post some audio so you know what I mean.

Me thinks a circuit bent 'Bass Balls' pedal could be next! Nice and formanty!
