Moog Grandmother playing Voodoo People

video upload by fischek

"After fiddling with my grandmother for a while (sounds very wrong :D) I've stumbled upon a sound that resembles the one used by Prodigy, so decided to record it just for fun...

Btw, I know Liam Howlett used to own a Moog Prodigy (hence the name) and am now wondering if that' the one he used for getting this sound."

L-Fusion Dual Analog Triangle VCO 18HP Eurorack module review

video upload by LFusion Electronics

Update: Reworked video demo - Music first, explanation second.

The module is now available on Reverb.

"Introduction to Dual Triangle Core Voltage Controlled Oscillator – Fully analog 18HP Eurorack module, contains two identical VCOs, each oscillator is based on super stable analog SSI2130 VCO IC served by 46 opamps doing precision analog math. In total there are 34 analog ICs and 449 other parts.

In analog VCO sound wave is generated by charging and discharging precision capacitor controlled by temperature compensated exponential converter, generated triangle wave then goes to wave shapers producing different wave forms. Such technology produces supreme audio quality.

Pitch is tuned to standard 1 volt per octave, oscillator provides excellent tracking across 10 octaves, it can be tuned with precision of +-1 cent or 0.01 semitone, this is very precise as human ear can detect detuning from around 3 to 5 cents.

Module can be ordered on E-Bay:"

"Dual analog triangle core voltage controlled oscillator (VCO) 16HP Eurorack module with through zero FM modulation based on SSI2130 ICs that provide precision analog exponential converters, oscillator cores, waveshapers as well as high quality voltage controlled amplifiers for wave mixing. Each VCO in the module outputs sine, triangle, saw and square/pulse waves,also voltage controlled mix of them with sub oscillator an octave below controlled with integrated crossfader mixer.

Both oscillators can be modulated with exponential and linear FM, as well as through zero FM/PM and pulse width CV. To ease modulation for each oscillator we have added separate sine outputs with variable gain controlled with modulation knob.

Module also offers master crossfader to mix the outputs of the two oscillators, octave selector switch for each oscillator, as well as knobs for shape, pulse width, pitch and fine tuning. Module is designed using precision voltage reference and other high quality components to achieve +/-1ct (+/-0.01 semitone) tuning across 10 octaves- well below human ear pitch sensitivity which is around 3-5ct.

All inputs and outputs are ruggedized - able to handle rail to rail voltages +12V..-12V."

Testing Basic Preset Function Implementation Arduino 8x8 Drum Sequencer

video upload by Unrelated Activities

"Now using the Arduino Nano EEPROM (1024 bytes) to store some preset patterns. Each pattern size is 64 bytes, so there is room for 16 presets. The presets were written to eeprom before uploading this sketch, for now we just read and load them to the steps[][] array. 8x8 sequencer, very basic in its features. The interface is composed of two rotary encoders with switch, and a 128x64 I2C OLED display. The display presents an eight rows x eight columns grid, rows are steps, columns are tracks. Encoders are used to navigate through the grid coordinates, The X encoder switch selects Cursor or Write mode, in Cursor mode an'x' is shown on the grid and a 0 is written in the selected slot in a bi-dimensional array, in Write mode a filled square is drawn on the grid and a 1 is written in the selected slot in the array. The encoder Y switch has three modes: Edit, Tempo, and Play. In Edit mode the sequencer pattern can be created, in Tempo mode the Y encoder sets the sequencer BPM (Beats Per Minute), in Play it plays the pattern. The right side of the display shows the BPM and the current mode, the left side shows a rectangle indicating which step is being played. Each track fires a gate using eight Arduino pins (0 - 4.7V) and also sends MIDI notes through TX pin (channel 10, GM drum notes 35, 38, 42, 46, 45, 50, 64, 76). It works, but the display is too small for my eyes... Code is in a pinned comment."

Soundtrack music with Korg ARP Odyssey, piano, Dreadbox Typhon, and Nymphes

video upload by Jay Hosking

"A song comprised of two live performances with both hardware and software.

I have a hand surgery scheduled for this week, and wanted to get in one last piano performance before my hand was out of commission for a while. These are the results. The end result seems clearly inspired by some of my favourite OST music.

Native Instruments Noire (played on Kawai CA49) - piano
Korg ARP Odyssey - melody
Arturia Analog Lab and Dreadbox Nymphes - pad
Reason Thor and Dreadbox Typhon - bass
Red70 controlled by MIDI Fighter Twister - doubled right hand piano arpeggio

Recorded as two live performances into Reason Studios' Reason. Additional effects (mainly Arturia and Reason) added in the box, plus EQ, compression, and limiting on the master.
