Inside an Akai EWI 3020m Analog Synth Module

"I'm not much of a wind player - mostly I goof around with my Casio DH's, but this EWI3020+3020m set was on ebay for a good price because it wasn't working.

I knew the 3020m was an all-analog synth, but I didn't know what the hardware inside was (and the service manual isn't floating around on the web).

Turns out it's got some solid CEM voicing, with some pretty decent matrix modulations possible, managed by the 78cXX micro. I haven't hooked it up to a midi keyboard yet, so I don't know if it's workable as a rack monosynth.

These are just some photos of the inside and outside of the unit. I wonder if this is the very last of the first era of analog synths (late 60's to mid 90's)?"

"Single board synth on the inside, surprisingly simple with minimal components..."

"push.pull
pulse synth harmonics
phase (un)locked loops

The push.pull pedal is a synth effect based upon the PLL (Phase Locked Loop) IC, in which the PLL has been "unlocked" and let loose through joysticks, switches, and a pushbutton. It is hard to describe the sounds I have already heard: distorted, glitchy, fuzz, bass synth, drone, full of clicks, 8 bit, and erratic synthetic hyperdrive.

4 Non-Return to Center Joysticks
A green LED pushbutton that "unlocks" the pedal, allowing it to spiral out of control.
4 switches: Capacitor Envelope (Slow, Slower, Bypass) High/Low Tone Select Feedback Select (Audio, Voltage, Bypass) True Bypass
In/Out/Power

Low profile aluminum enclosure

I will add graphics.

Ridiculous. Insane. Brilliant. Wrong. Some adjectives I have heard to sum up musician's first impressions. I am flattered.

Why? Because I love the delicate monstrosity that is precarious noise. I also wanted to make at least an entry into the category of craziest pedal ever. Hope I can be yours.

I will manufacture these. Since I am emerging as a pedal artist, I will do a limited run of these (say about 10) over the next month or two. I am looking for investors and/or a collaborators smarter than me in the area of engineering and electronics, so that the push.pull can be even better. In the meantime, I will post videos and experiment and refine. If you would like one, email me about your interest at either pushpullpedal@gmail.com or coloringpad@gmail.com and I will keep you posted and definitely email you when they are ready.

Price? Not there yet. I'll know more soon.
