Groove TV: Circuit Bending & Beyond (HD Video)

November 23, 2014 · Posted in Uncategorized · Comment 

In this episode of Groove TV the Berlin-based sound artist Derek Holzer gives an introduction to the subculture of circuit bending and do-it-yourself electronics. Without any formal training in either music or electronics, Holzer decided to try his hand at building his own instruments and subsequently developed the design for his “SoundBoxes”.

Introducing the Beat707 XXL LE – DIY Drum sequencer

November 23, 2014 · Posted in Uncategorized · Comment 

This is the Beat707 XXL LE – Limited Edition – no LCD and no SD Card, less components, minimal interface.

http://www.Beat707.com

For more details, visit our Facebook Page

https://www.facebook.com/beat707

Beat707 XXL LE has only MIDI output, no LCD and no SD Card. Uses the ATmega328 EEPROM to store data. This unit can handle 8 drum tracks, 2 accent tracks and 6 patterns. Each pattern is actually a combi of 4 x 16 steps plus extra double steps. So in total we have 128 steps per pattern. We have setup a very easy way to edit all those steps. We have steps A, B, C, D for each set of 16 steps. Also, you can set a set to “double-step” and it will blink instead of light-up. All options are set into the program itself which can be altered and uploaded using the Arduino IDE.

– Uses only Two ATmega328 Chips and basic components.
– Work with a 500mA 5V power supply.
– Can use 4 pin mic left and right connectors, instead of 6 pin mic connectors.
– Settings such as track drum notes and midi channels are set in code, while BPM and Steps# can be changed in the interface itself and is saved along the other data into the internal EEPROM.
– Multiple units can be side-chained.

Check out the new SparkPunk Sequencer!

August 31, 2014 · Posted in Uncategorized · Comment 

The SparkPunk Sequencer is a musical control voltage sequencer designed to control the SparkPunk Sound Kit. With the pair, you can create ten-step musical motifs, but there are hidden opportunities in the sequencer: it can be modified and connected to external hardware in clever and interesting ways. The SparkPunk Sequencer cycles among ten steps, reading the slider and switch for each, producing corresponding analog voltages on the output pins. It offers hands-on control, with its array of knobs, sliders, and switches while seamlessly integrating with the SparkPunk Sound Generator for your creative musical enjoyment.

Sparkfun has published a Theory and Applications Guide for the Sequencer Kit that explains how the sequencer works and also details several useful mods. Mods include adjustable sequence length, CV out for standard analog gear, synchronizing sequencers and more.

Note: The Sparkfun Sequencer is a solderable kit with lots of parts.

The Sparkfun Sequencer Kit is available for US $59.95.

Mini OONTZ – 3D Printed MIDI Controller

August 3, 2014 · Posted in Uncategorized · Comment 

In this project we’re building a diy midi controller that works with ios devices and analog synths. Say hello to OONTZ, the open source button grid controller based on the adafruit trellis. The mini OONTZ is a 3d printed case housing one trellis and 4 potentiometers ideal for a 16 button drum pad. OONTZ works with any MIDI software and hardware. No more virtual midi or serial to MIDI stuff, oontz is legit USB MIDI.

Say hello to OONTZ, the open source button grid controller based on the Adafruit Trellis button platform.

Adafruit Trellis
This PCB is specially made to match the Adafruit 4×4 elastomer keypad. Each Trellis PCB has 4×4 pads and 4×4 matching spots for 3mm LEDs. The circuitry on-board handles the background key-presses and LED lighting for the 4×4 tile. However, it does not have any microcontroller or other ‘brains’ – an Arduino (or similar microcontroller) is required to control the Trellis to read the keypress data and let it know when to light up LEDs as desired.

We build our own full-size MS20, add a filter selection switch and compare with an original.

Korg MS20 Kit Build Timelapse

April 4, 2014 · Posted in Uncategorized · Comment 

I built the MS20 Kit – one of only 1,000 available. Be sure to check out our full review coming soon. Music: Intellijel Atlantis through Behringer X32 with Vintage Room freeze reverb for pads, stereo delay.

The MS-20 Kit is a true-analog, 1:1 scale reissue of the MS-20, with both filters built in (the more aggressive early production filter and more mellow late production one). Every details has been replicated, right down to the packaging, which includes a letter from the original MS-20 engineers and the President of Korg, Inc.

The Korg MS-20 kit has a street price of about $1,400.
