Berlin Workshop February 2016

We will be hosted at the fantastic c-base Raumstation in Berlin for a pair of module building workshop dates : February 20 and 21 (Saturday and Sunday). The hours are Saturday 2pm until 8pm and Sunday 12 noon until 8pm.

The workshops are free of charge, you only pay for what you build and take home with you. The assembly is relatively easy, no previous soldering experience is required. We will be on hand to help throughout, should you have any problems.

People of all ages and abilities are welcome, under 12s should be accompanied by an adult.

Modules available to build :

PowerKit and mini case

The PowerKit is a combined busboard and 200mA per rail PSU with +12/-12/+5v rails, suitable for small to medium sized portable cases (case and modules not included!).

Note that these are special workshop prices which are only possible thanks to the volunteer efforts of the organisers.

If you are interested in attending please let us know by filling out the contact form below.

OOOOPS! We’re having some technical difficulties! The form was not working earlier, please contact us by sending an email to info at rebeltech.org – thank you!

Amplitude and Pitch Triggers

Our signal parameter space is many-dimensioned and infinitely detailed, with analogue control voltages from sources such as envelopes, sequencers and low frequency oscillators. Regular triggers and gates however are blunt, inefficient and in need of an update.

We propose two rich triggers to complement simple binary triggers to make better use of those signal paths. And to open up a new realm of patch possibilities.

The idea is not new: combine triggers with accents, so that strong triggers (typically greater than 5v, here we use a 1v threshold) play louder than soft ones (closer to, but not below, the trigger threshold). We will formalise it slightly differently and combine the notion of a ‘tuned’ dynamic scale, just like we have a tuned 1v/octave pitch scale.

Amplitude Trigger
1v/24dB
If 6v means as loud as it goes, then 4v means 48dB less. 0 to 1v means no trigger. From 1v to 6v there is 120dB dynamic range.

Pitch Trigger
1v/octave
A signal level below 1v means no trigger. 1v to 6v spans 5 octaves.

Many sounds, such as percussion and plucked strings, have an intrinsic amplitude envelope. Meanwhile our modular patch habits are linked to a de-constructed approach to synthesis. Typically your envelope will control your VCA which controls the volume of what you hear. What if a VCA was incorporated into the envelope, so that you didn’t have to patch up another module? Now imagine that you can send it a special trigger, one which not only starts the envelope, but also sets the overall amplitude.

This special trigger, the rich trigger, can also be an accent to percussion, the cutoff for a filter, or the pitch of a sound generator.

The proposal here is not to replace CVs or envelopes or anything, only to add quality to simple triggers and gates.

Consider the information that the rich trigger carries. Firstly, binary: is it on or off. Second, temporal: how long is it on for. Third, cv: what is the trigger level. Lastly, while on, the level can be modulated: it can change continuously.

These new triggers are of course compatible with other signals in your modular system. You can use the output of an envelope as a rich trigger, or an LFO. Simply add an attenuator to a binary trigger to make it rich. Merge a simple trigger and a CV signal into a rich trigger by gating with a 1v offset. Split the rich trigger into trigger plus CV with a comparator. And the same simple rule of modular applies: patch anything into anything!

Workshops in Tilburg and Barcelona

The workshops are free of charge, you only pay for what you build and take home with you. The assembly is relatively easy, no previous soldering experience is required. We will be on hand to help throughout, should you have any problems.

Modules available to build :

Note that these are special workshop prices which are only possible thanks to the volunteer efforts of the organisers.

If you are interested in attending please let us know by filling out the contact form below. Our previous workshops have all been very successful: everyone goes home with a brand new, fully functional, self-made module – some with two!

PowerKit and mini caseBoth of the workshops are part of bigger events. In Holland we will be at the massive Incubate festival, and in Spain we’re joining Barcelona Modular Day 2. There will be lots of other great workshops, exhibitions and performances, so check the program and come along if you can!

The PowerKit is a combined busboard and 200mA per rail PSU with +12/-12/+5v rails, suitable for small to medium sized portable cases.

OWL Modular Demo

We’ve made a little demo video in the studio, showing off a few of the OWL factory patches. The video also covers how to change between the 40 patches that come pre-loaded, and how to load patches from the website.

OWL Modular Launch Event

OWL ModularWe’ll be holding a little launch event for the OWL Modular at the London Music Hackspace, this Saturday 1 August at 5pm. Come down to see us and get hands on with the new arrival!

We’ll be showing off the sonic capabilities of the patch library as well as demonstrating how to load up Faust, C++ and Pure Data patches. Bring your own code!

See you at the Music Hackspace, Unit 15, (ContainerVille) 5 – 10 Corbridge Crescent London E2 9DS.

Chronos Demo Video

We finally got our act together and did a demo video of Χρόνος, our little 6hp tap tempo module with tempo synced LFO. Now you can always be on time. Enjoy!

OWL Modular Release Announced

The hotly anticipated OWL Modular will be released on 1 August 2015. The module incorporates a high performance programmable DSP core, stereo audio at up to 96kHz / 24bits, and CV controlled parameters.
OWL Modular
Based on the highly successful OWL Pedal, the Modular makes use of the same patches while adding some truly modular features. Effects and synthesis as well as complex sequencing and triggering is all within its remit. Already the OWL patch library contains more than 70 effects, including phasers, flangers, delays, reverbs, distortion, compression, filters, shifters, screamers, laughers…

For more information, patches, and documentation see the OWL website, visit our (preliminary) product page, or watch this video:

Minimalism: from plainsong to Bit Reactor

Our recently released Bit Reactor module features briefly in a segment on Minimalism by Financial Times.
BitReactor on FT

In the clip, renowned British electronic musician and composer Scanner (Robin Rimbaud) talks about Minimalist music and its impact on contemporary culture. Scanner performed his piece Tavener Deconstructed/Reconstructed at London’s Kings Place as part of the ongoing series Minimalism Unwrapped.

Minimalism grew out of 1960s counterculture in New York and California but has its roots in early church music. The FT’s Laura Battle meets composer Stephen Montague and sound artist Scanner, and the London Sinfonietta rehearse Terry Riley’s ‘In C’.

(Impatient? Robin is interviewed at 6:40 and the Bit Reactor comes into view at 8:20!)
