SoC+FPGA Synthesizer

video upload by Laura Regan

"This is a demonstration of my final degree project for my Bachelor's Degree in Electronic Systems Engineering. For my project I designed a digital music synthesizer on a SoC+FPGA, the Zynq 7020, on a Zedboard development board. All audio synthesis and digital signal processing is performed in real time on custom hardware modules designed in VHDL using Xilinx Vivado.

The synthesizer includes the following modules:
- Numerically Controlled Oscillator
- ADSR envelope generator
- Numerically Controlled Amplifier
- Numerically Controlled Filter
- Low Frequency Oscillator
- Mixer

The synthesizer has a polyphony of 128 voices. The filter is a digital implementation of the famous Moog Ladder filter. Control of the synthesizer's modules is managed by the on-chip ARM processor. The processor also receives commands from the synthesizer's interfaces. A virtual interface was designed in Qt and a physical interface was designed using the on-chip XADC for reading the values of the interfaces dials. A MIDI interface PCB was designed to allow MIDI equipment such as keyboards to be connected to the synthesizer.

In the video the effects of multiple modules are demonstrated, the virtual interface was used to control the synthesizer and Digilent's WaveForms oscilloscope was used to view the synthesizer's output."

video upload by Joranalogue Audio Design

"It's our take on the classic subharmonics generator patch in today's #PATCHTUESDAY video! A gated switch 'masks' the trigger signal during the rising stage, turning Contour 1 in a frequency divider. What's your favourite C1 #eurorack patch idea?"

05-The UDO Super 6-DDS2 (2nd oscillator)-Part B

video upload by AutomaticGainsay

"Here is the second part of a two-part demonstration of the second oscillator (DDS2) found on the UDO Super 6.

The theme for this demonstration was recorded by multitracking the UDO Super 6 in order to provide the various parts necessary. No external equalization or effects were used. The drums were created through programming the Korg Triton LE and processing the results through the Landscape Stereo Field."

VAI 34 Wersimatic II / Farfisa Syntorchestra

video upload by Vintage Audio Institute Italia

"Analog auto-accompaniment machine produced by the German organ manufacturer Wersi sometime in the mid-70s. Originally part of a big, dual manual organ called Helios, this auto-comp section was probably removed from the organ and squeezed into a Teak cabinet, crammed with circuit boards, all beautifully snug inside - a very good job by whoever built it.

You control the harmony and key with the black 12 buttons on the front replacing the one octave that was probably at the bottom 12 keys of the organ.

The Wersimatic II has sections on board: Bass
Drum machine
Various chord sounds

Melody played on the Farfisa Syntorchestra String machine and Mono synth.

Big thanks to Organfairy who helped us find the right schematics to repair it.

Vintage Audio Institute Italia is a gear vendor and recording studio in the hills of Florence."
