Feedback modules Pre KM

This module is based on a famous mixer. As feedback modules tells us: Sound design channel strip based on a famous late seventies small mixer used by many electronic music bands. I like this one as it can overdrive drum sounds quite nicely. The chip it needs can be hard to find.

Feedback modules Pre CR

This is a modules based on a famous mixer. As feedback modules tells us: Sound design channel strip based on a famous late eighties small mixer used mostly for the well known TB303 distortion sound. Well indeed it does. It can overdrive your sound but still makes it sound awesome. I believe this was the one where you need to match you transistors.

Feedback modules Static

I bought this after the 1bit delay cause I was loving there build manuals and I was in need for some noise. Well this modules just makes some noise. From white to pink and dark and digital. If you are in need for noise I can recommend this module. Its also available as a build module. I build the THT version but there is also a SMD version. What more can I say about it.. it’s noise

Feedback Modules 1 Bit multi-tap Delay

Oh this one I love so much. Still think about building a second one. These delay is something special. During the build I feel in love with how they have made the manual. Even if your not building this check it out I think it’s one of the best way to make a build manual. The sound this thing can produce is amazing. All depends a bit on how you calibrate it. It can be very clean but also take you to distorted territory

The nice thing is you can output both taps and make it into a “stereo” module. Shipping did take some time but if you are looking for a special delay put this one on your short list and be sure to check out some YouTube videos.

It can also be bought as a build module from feedback modules

Hexinverters Mutant Snare

For some people it is the best snare they have. I don’t like this one that much. Maybe I need to do some calibration on it again. I read more diy version are difficult to calibrate. It should be a 808 snare and like the Hihat and bassdrum it is designed on the 808. So don’t know why I don’t really like it but it is what it is.

Difficulty to build: Medium to hard, Has multiple pcb’s and can take some time to build

Hexinverters Mutant Hihats

After the bass drum I build the hi-hats. These are also based on the 808. I really like the fade switch. This can close the open hi hat when the closed one is hit or can leave it open, or somewhere in between. It has a great effect on the decay of the open hi hat. It takes external noise if you want to.

I’m a big fan of this hi-hat. the one think I would change is the panel color, because I like black panels more. Maybe I will change that in the future.

Hagiwo Quantizer: how does it work, a bit of background

The Quantizer made by Hagiwo is a Arduino based quantizer. Hagiwo published all files and schematics. The code is readable and not packed into a hex files. I have put my own twist on the design by replacing the DAC.

The original post and design by Hagiwo can be found here:

So lets take a look on how it’s build and how it works.

Dotty: Buttons orientation (thanks Beta Testers)

I was in the wrong impression the orientation of the Dotty buttons didn’t really matter. I did place them all in the same orientation, didn’t mix it up but didn’t check also. Later found out I was lucky on most of the Dotty’s I build.

The buttons are read by a 4051 chips 8 buttons at a time I call them rows. All four rows worked most of the time. But one build had a problem with row three. When installed in one way the buttons Dotty stop recording steps. I rotated the buttons and Dotty worked again.

Thought it was strange never had it before on the previous versions, put it aside as a glitch to sort out. Then a beta tester reported the same. Now I had to dive into this problem and fix it.
