Control Voltage for the Monotribe – Part 1: Making an Adapter Cable

I always used MIDI. I am very familiar to MIDI: from the communication between Pure Data and my software synths, to my PCR-500, when using the Volcas or the Microkorg… So I never understood all the fuzz about Control Voltage (CV)… for me it looked like a relique from ancient times. I even brought the DinTribe adapter to hookup my Monotribe to my other synths and controllers.




When the 2.1 firmware update for the Monotribe was release, it added CV-Gate input connectivity. Since now I am the proud owner of a MicroBrute and a SQ-1, I decided to give it a go. This is how I made the cable adapter for the Monotribe, how I calibrated it and also some ideas I had during my experimentation. This text is accompanied by YouTube videos showing the steps I took.

January Updates

It’s been a while since I write on this blog, so here’s a quick summary of the end of 2015, and plans for 2016.

By the end of October I knew I was meant to go to India on work, so I spent most of my spare time in November preparing for the trip (doctor’s appointments, visa, flight plans, touring plans, etc). On December first I took the long and boring Porto-Frankfurt-Delhi-Lucknow flights, followed by a two-hour drive to Kanpur. While I was in India, this website, and the Volca Sample Tutorial Series were feature in an article in Synthopia, which was overwhelmingly great.



I arrived back at home on December, the 16th only to find out my lab was going to be closed between Christmas and New Year’s day…. Continue reading “January Updates”

Korg Volca FM

I fist thought this was another spoof. It looks uglier than the other Volcas, but it sounds great, and at the end of the day that’s all we want! So excited about this… I’m already scripting the tutorials!!! :D

This month’s header: October 2015

This month’s header picture is a variation on Mandelbrot’s set (M set) done on Xaos. If you have a Mac or Linux machine and some interest on fractal geometry, you should try GNU Xaos. This small program let’s you explore several known fractals interactively. It will also record your explorations in video, or take snapshots.

The original Mandelbrot’s set is defined as the set of complex numbers for which the iteration z ↔ z²+c  is convergent (the symbol should be a double harpoon, but I cannot make it render on all browsers). Contrary to other programs, Xaos let’s you edit the formula that generates the fractal (you are still limited within certain families of fractal, I think). Just for fun, I put the formula z ↔ z²+ 0.99*c and this resulted on a distorted M set, that still resembles the original one, but lack much of the original symmetry.

The image was then edited in GIMP: the colour space was altered, the low contrast area was blurred and darkened, and a brighter blurred overlay was added to make the picture  “glow” a little bit.
