This is today’s improvisation called African Night. Its a bit like the sights and sounds of a colourful land and the sound of the night, including the Earth and the sound of Cicadas. It’s quite high frequency rich (as is the sound of Cicadas in the wild) so listen to it with low, almost atmospheric volume.
Online improvisation with Nicola and Yati 05.02.2021
Tonight was an improvisation session with cellist Nicola Baroni; this time working with the new feedback systems together with the geometric audio effect formations. Unlike last session, in which I used an envelope follower to alter the effect outline of the visuals, I sent the signals instead to the VCOs of the 3Trins which created a more complex sort of visualisation feedback. This was not as effective in relaying the visual information online, especially since there is a lag on the performer’s end. Never-the-less, the layering of the active formations in the form was very pleasing and at times almost like a hand-drawn animation or like the forms of Walter Ruttman from the early 20th century. We will aim to attempt the next session with perhaps a mix of techniques from the last session.
Note: the interface on Nicola’s end was acting up, so the signal is not very clean. This is an experimental recording but also nice to watch!

This last week: Feedback! (processes)
I’ve been very active this week experimenting with works utilising various feedback perimeters, between Structure and 3Trins modules, but also internally via feedback nodes in the Structure. Some of the works have been directly “composed” with audio circuits simultaneously, but many have been produced “silent”. I don’t think these processes are intrinsically much different from each other anyway…
The feedback processes obviously can create “infinite tunnel” style effects, particularly when they are controlled with LFO’s or audio signals, but they appear to really come alive when exploring the various signal settings and parameters to find “fringe events”, which create sometimes unpredictable outcomes. In particular, when interfacing the digital Structure with the analogue 3trins, there are some voltage variable situations in the pathways that make them seem particularly organic.
Perhaps expectantly, the outputs are tending to mimic Saundaryalahari geometric and organic forms (triangles, lotuses, etc.) which, I don’t pretend to imagine are not just “what I want to see” however, it is interesting with the control parameters used to create them involve feedback processes - thinking about how the Saundaryalahari involves symbiotic co-creative processes - so that is certainly feeling right!
