MonoTon Arduino Based Step Sequencer & Software Synthesizer by Tho Mai

Published on Jan 7, 2017 Tho Mai

"For more information & source code see: https://github.com/thomai-d/MonoTon"

"Features

8 instruments (Kick, Hat, Snare, Shaker, Clap, Noise, Sine, Square)
Each instrument has 4 banks a 16 steps each and can be muted
Synthesis using 8bit wavetables
20000Hz sampling rate
Master is filtered through analog high-pass filter (2pole)
Hardware

atmega1284 @ 16MHz using Mighty1284 platform
lots of 74HC595 shift registers (for LEDs)
MCP23S17 port extenders (for buttons)
CD4067 multiplexer (for analog potis)
R2R network for D/A conversion
Some eagle files included
Lessons learned while developing

The analog inputs are quite noisy. De-noising uses quite much cpu.
Don't ever solder this much wires by hand. PCB services are your friend.
Prefer DDS over an R2R ladder.
Open bugs / flaws

Although the output is buffered by an opamp, the sound sounds distorted when using the PC's line in. If I conntect it directly to the speakers, the sound is quite clear."

Roland System-1 - Self Resonance demo

Published on Jan 7, 2017 Alba Ecstasy

"A small video showing the Roland System-1 in self resonance. All oscillators has been shut off and I only juggled with the cutoff and the resonance.
In addition, I played with the:
- filter and amp envelope and
- different LFO waveforms but only to alter the filter so I can create pitch.
I added the onboard reverb and delay to flavour the sounds!
Later I added a little noise to vary the sound and in the end a opened the oscillators to hear the difference (just a little bit)."

Free Roland JX3P - Bass Sample Pack from Seaweed Factory

via Seaweed Factory

"This sample pack is the third of three in a series of packs featuring the Roland JX3P Synthesizer, released in 1983.

The third pack focuses on bass patches. It also includes a vibes patch.
The four patches included have been multisampled directly from the synthesizer. The JX3P can produce 61 notes, starting at C3 (midi note 36) on up through C8 (midi note 96). Each note had been individually sampled for an extended period of time to capture the behaviour of the built-in chorus. Samples are labelled by patch name and midi note number. Each folder contains a full set of all the sounds the JX3P can make for that patch."
