Hell Synth: DIY Digital Noise Terror

March 30, 2015 · Posted in Uncategorized · Comment 

A powerful little drone synth you can get prebuilt or make yourself. Want a different synth? Just swap the chip for a different program

The “Hell Synth” is a palm sized experimental synth you can buy prebuilt or as a kit. Little noise synths are often limited in the scope of their sound, either they grind aggressively like dive-bombing aeroplanes, or drone in massive arrays of humming square-waves.

THIS HELL SYNTH IS A LITTLE DIFFERENT! The range of sounds that come out of this little box will keep you twiddling for hours. There are oceans of glass, lightening fast arpeggios, swarming notes that dance in and out of phase.

This is the fifth version of this synth design and the tenth version of the software. Ive been working to make sure it is fun to use while being full of awesome sounds.

So far there are two programs I have written for it including:

FROM HELL!!! :
This is a hard-core noise synth with six digital wavetable oscillators, tons of glitch, modulation and waveforms. It also has midi out.

Synthino XM Newest Polyphonic MIDI Synthesizer LFO Filter Groovebox Arpeggiator Drum Samples

February 23, 2015 · Posted in Uncategorized · Comment 

The Synthino XM is completely new polyphonic synthesizer with unique features running on a powerful hardware platform. It is compact, well-constructed, open source, and absolutely beautiful. Most importantly, it is really fun to play whether you are a musician or you just want to make some noise.

Synthino-XM

Synthino XM is a polyphonic, multitimbral synthesizer with many features:

  • 5-note polyphony for superb playability
  • 12 waveforms, 4 drum samples
  • 12-bit audio at 25KHz output rate
  • 4 MIDI channels, each with separate waveform and ADSR envelope
  • low pass filter with cutoff frequency and resonance controls
  • 2 independent low frequency oscillators (LFOs): pitch and filter
  • selectable waveform for LFOs
  • 1V p-p audio output voltage with enough current to drive headphones
  • arpeggiator mode, up to 16 notes
  • 4 arpeggiator patterns: up, down, up-down, random
  • 4 built-in arpeggiator chords or use MIDI to specify up to 16 notes
  • arpeggiator pitch transposition control
  • tempo control with MIDI clock input
  • 16-step live performance “groovebox” sequencer
  • pitch fine-tuning adjustment
  • programmable/upgradable over USB

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.

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.
