NESizer - 2A03 based synthesizer

Published on Aug 3, 2014 Johan Fjeldtvedt

"This is a project using a microcontroller to make an RP2A03 IC (the sound / CPU chip used in the NES and Famicom consoles) produce sound.

For more information, schematics and source code, take a look at https://github.com/Jaffe-/NESizer2"

Note this is the first NESizer post.

Roland DEP-5 demo

Published on Aug 3, 2014 SynthMania

"Demo of a few patches on the Roland DEP-5, a digital effects processor from 1986."

Benjolin

Published on Aug 3, 2014 synthdood

"Benjolin for Euro rack with built in 1/8" outputs and normalized for modular synth signals. This little analog synth makes the most AWESOME sounds! I have never heard another synth make sounds like this thing. It will play itself and change over time even if you don't touch any of the controls. Very cool!"

New Doepfer A-138u Dual Micro Eurorack Mixer

"Module A-138u is a simple, low-cost mixer with two units.
Each unit is equipped with three inputs and one output.
The upper unit has for each input a trimming potentiometer available that allows to adjust the amplification in the range 0...+1 for each input (factory setting is 1 for all inputs).
The inputs of the lower unit all have the same amplification +1.

The output of the upper unit is normalled to the first input of the lower unit.
That way the module can be used also as a mixer with five inputs: for this the inputs 1, 2 and 3 of the upper unit and the inputs 2 and 3 of the lower unit are used.
The sum output for all five signals is then the output of the lower unit.
As soon as a plug is inserted into input 1 of the lower unit the module becomes a dual 3-in-1 mixer again.
Inputs and Outputs are DC-coupled, i.e. audio and control signals can be mixed.

Application examples:
- Mixer for audio signals, e.g. three VCOs preceding a VCF, when the amplifications are adjusted slightly different no signal extinction occurs during the beat of the VCOs
- Mixer for control voltages (e.g. LFOs, envelope generators, random voltages)"

The module is planned for fall 2014, for a price around Euro 45.00
Price and release date are still without obligation !"

"the AX60 is among some of the last true analog polysynths of the mid-eighties. It was Akai's answer to the hugely successful Roland Juno series and Yamaha's new digital DX-series. The AX60 is a programmable six-voice synth with a nice LFO, lowpass (VCF) filter, envelope sections, and more."

"Here's something you don't see too often! This module was built for me on request by the great Gotharman, and is a clone of the Steiner Synthacon multimode 2-pole. Sounds really gritty with high resonance, especially when blending filter types!

I should mention that this particular module is a very tight fit into my Eurorack case, although you may not have this problem. The dimensions are a bit weird and it may require some maneuvering."

Vermona Analogue Synthesizer SN 214904

via this auction

"Vermona Dual Oscillator Analogue Synthesizer circa 1980. Genuinely rare item - grab a piece of East German / Soviet electronic history.

Cold War Sonic Weapon. Looks like a control panel from a 70's sci-fi film. Built like a tank, wooden end cheeks.

Dark, menacing, fat bass sounds as well as bright, soaring leads.

All functions working, pots cleaned recently so nice and smooth. Cosmetic condition pretty good, just the usual wear and tear for something of this age.

2 minor issues - the on off button never switches off (just unplug it) and a couple of keys pitch drift sometimes upon release (never bothered me as both oscillators have 5 octaves, and second oscillator can be tuned up or down a full octave). Likely a fiddle around with the key mechanisms would sort this."
