1. VCS3 Repair & Mods Part 1

A dead VCS3 hits the bench. What could have caused this nasty chain reaction?

2. VCS3 Repair & Mods Part 2

In this episode we repair the blown MFC6070 by replacing it with the MFC234 from
http://www.portabellabz.be/synthipcbs...
This replaces the unobtainium part and swaps it for the more 'sought after' germanium transistor design.

All synth sounds are direct recorded examples of this VCS3.

3. VCS3 Repair & Mods Part 3

In this video we continue with the addition of Buffers for the Pin Matrix. This allows for accurate splitting of CV's.
This video will demonstrate the before and after effects of adding these buffers.
The PCB's are available from
http://www.portabellabz.be/synthipcbs...

4. VCS3 Repair & Mods Part 4

In this final part we add a Sample and hold modification from the fantastic http://www.portabellabz.be
The sample and hold modification (which comes pre built) can be found here

After which we try out the VSC 3 as a Paraphonic synth utilising the previously installed Channel 3 input. Silent way Voice Controller was used to control its polyphony.

Retrovirus basic cv in DEMO

"Here is a simple demonstration of a 10V peak to peak LFO (+/-5V) controlling each stage of the envelope."

RNA Retrovirus Teaser

Published on Aug 24, 2018 Really Nice Audio

"Here is a teaser video of our Retrovirus Dual envelope module for Eurorack modular.
You can drive both envelopes from one gate or use both gate inputs for independent control.
There are dedicated CV control of A,D,S and R for both envelopes.
Each envelope has a 5V and a 10V output.
More detailed overviews to come."

RNA 2CPO INTRODUCTION

Published on Jul 27, 2018 Really Nice Audio

"The 2CPO audio to trigger convertor is a slim and simple way to control your modular from a spare of outputs on your sound card.
It works great with a pair of hardware sampler outputs enabling easy syncing of modular to sampler sequencer.

In this demo we connect the outputs from a sound card into the 2CPO. The outputs from the 2CPO are connected to the CLOCK and RESET inputs of a Music From Outer Space 16 step sequencer.

With slight modification the 2CPO can also be used with phones etc enabling sync over wifi with app like Ableton Live."

"This 2CPO module is a 2 channel audio to trigger convertor. It can enable 'audio engine locked' sync of hardware sequencers as well as many other duties.

OPTIONS:
The REGULAR option is suitable for Balanced to Unbalanced connections. This has RED LED's.
The PHONE option has a higher gain setting suited to mobile phone output levels (for use with Ableton Sync etc.) This has YELLOW LED's

Come with Power Cable, Screws and Washers"

RNA vactrol crossfade fun!

Published on Dec 16, 2015 littlem4tt

"Just messing around with a vactrol crossfader on the breadboard and then controlling it from the silent way lfo.

The bass sound is a system x oscillator and the other input channel is an fm sound which is a sys x osc modulated by the sine wave output from the yusynth osc.

The output from the crossfader is then fed into 1 channel of the stereo hearne morley HM2040 filter (12db)."

Sequential Switch Fun!

Published on Jun 23, 2015 littlem4tt

"Here is a demo where I send the gates from the sequencer through the ken stone sequential switch to the vca's of 4 independent synth patches. I used the Yusynth Clock divider to change the speed of the sequential switch.
The pitch cv from the sequencer passes through the Penrose quantizer before being distributed by an RNA REPLICATOR."

ribosomal 16s vs music thing radio

Published on Jun 19, 2015 littlem4tt

"Heres an OTT test of a Music Thing Radio. The Ribosomal 16s provides CV control of the Radio stations, in this case speeches from the free world. The Radio is triggered from a MFB drum sequencer.
Resistance is futile!"

RIBOSOMAL 16S CV CONTROL OF FM DEMONSTRATION

"I originally wanted to build the MFOS sequencer to control an FM modulation Oscillator. Here is my first attempt."

"What ya gunna do with those MFOS sequencer boards?
Build a eurorack version?"

Really Nice Audio - RNA Replicator, dualHMVCO1a & CV Mixers Eurorack Modules

The RNA Replicator - x8 CV Buffer Eurorack Module

Published on Feb 10, 2015

"Replicating the Replicator"

It looks like we have a new modular DIY maker. Really Nice Audio or RNA for short currently has three modules listed on their site, the replicator x8 CV Buffer (video above), the dualHMVCO1a VCO, and CV Mixers based on an adaptation of Ray Wilson's MFOS design.  Details on each captured for the archives below. They also do DIY synth mods and repair including work on the Yamaha DX-7, Korg Poly-61, Korg Monotribe, Oberheim DMX, and OSCar.

the replicator

"This versatile CV Buffer features 8 buffered outputs as well as 2 buffered inverted outputs.

The toggle switch inverts the voltage to the bottom 4 outputs.
2 bi-polar LEDs show the voltage polarity for each bank of 4 outputs.

It can also be used as a 2 x 4 channel buffer as inserting a signal into the IN2 socket overrides the bottom 4 outputs.

Comes with eurorack ribbon power cable and 2x 3mm screws."

dualHMVCO1a

"With 2 boards I claim 4 oscillators!!"

CV Mixers

"This CV Mixer system is an adaptation of Ray Wilson’s design found in his Multi-Function module from the essential MFOS website. I wanted to make a modular design with minimal wiring. All pots are soldered to the PCB whilst the sockets connect to a 5 pin single row IDC. This way you can use ‘each side’ of a 10 pin IDC to connect 2 mixers at a time to your socket panel. I made a socket panel which has 2 x 10 pin IDC connectors so 4 mixers can be connected. Built into my socket panel is a Common Input which buffers this signal each of the 4 CV 1 inputs. Inserting a plug into a CV1 input socket breaks the buffered signal.

This system I built for my 4x HMVCO1a so I have wired each mixer output to its corresponding oscillator via the ‘normalled’ pin each CV input socket.

Each CV Mixer gives you :

A coarse voltage bias

A fine voltage bias

3x CV inputs with attenuators

A bi-polar LED indicator showing polarity of voltage"
