In the past few months we developed a “vdPol oscillator and filter”. This device, named after its founder, is an interesting circuit which consist of multiple integrators (inverting opamp-circuit with an capacitor as feedback component) in a loop with signal multipliers (4-quadrant multiplier = AD633) .
I made multiple versions of the vdPol oscillator that can be used in combination with analogue studio Bea-5 (banana connectors) and the Doepfer set (mini jack connector).
At this point we still think the design of the vdPol can be improved. The tweaking and search of stability versus interesting sounds and behaviour is still in progress. To make the experimenting and tweaking more interesting, I designed a printed circuit board. Now more vdPol oscillators and filters can be connected together in one chain (or feedback-loop), creating very rich audio-patterns.
Friday 9th of February, I introduced students to the world of the Remote Controlled studio during a 2 hour session at Sonology studio Bea-6. It was an introduction lesson in how to use the RC-studio and how communication can be setup with OpenSoundControl messages (OSC).
Since the big Max/Msp patch that I made for driving the whole setup is quiet a mess (:) when you go out of presentation-mode, I added the core-processes as separate Max/msp patches. In this way it is easier building a patch yourself by adding the core-parts together. You will find patches that can work stand-alone and that generate the right OSC-messages like /v1, /cf, ma, /st and more. Take a look at the download section and find 7 new Max/Msp patches to be experimented with. For more information about the RC-studio, check this.
Example of the ADSR module drive:
After 4 years of hosting the Ipson webiste with Joomla 3.x, the amount of work for updating the website to a newer version of Joomla would have been too much (in my opinion).
I decided to host the website with another CMS: WordPress – it seems more elegant to work with so I will give it a try. The Ipson website structure will be the same as the old one, but in the background a lot of documents and images have been removed and it is more ‘clean’ at this moment.
Since I finished my master research in June 2017, I also have more new material the share on this website.The CompLex (OSC-driven audio-matrix), a new 16bit DA converters (still in the make) and much more interesting student projects. Also the development of the RC (Remote Controlled) analogue studio continued and will be shared on this website.
I hope you like the new setup.
