Here's my first video of a setup I've been working on for several months, called the Implication Organ. At its core is a Csound app (soon to be added to my GitHub site) running on a Raspberry Pi 3 with a Pisound card and controlled by a QuNexus keyboard and a Launch Control XL, which then feeds through a bunch of pedals. I've been making music with Csound for quite a while, and likewise with this sort of hardware, but it's new for me to combine those two worlds. There is more details about the setup in the video description. As well, Marc Weidenbaum has just written this up on his Disquiet site, and he has added the video it to his ongoing YouTube playlist of live ambient music performances (this is possibly the first one in the playlist that is based on Csound): https://disquiet.com/2018/07/09/simulating-environmental-byproducts/ Hope you enjoy it. I am planning on making more videos using the Implication Organ with different tunings and scales, though probably the next video will be a guided tour of the Implication Organ itself to explain how it works and what it does. |

Great tone and laboratory! Also thanks for sharing the details of setup it can inspire the community! I'm happy to see you involved with Indian scales! One side-note: it's cool to experiment with certain unusual notes, but I guess it would be interesting if you try to emulate tradition of the mode. So if we take the Marwa scale there are certain notes that are more prominent. Usually when musician performs Marwa we can hear the drone constantly playing tonic and seventh note it creates very unusual and specific to marwa mood. In most of the ragas we can hear the just tonic and the fifth, and it's very pleasant ratio, some ragas use tonic and the fourth. But in Marwa tonic and the seventh are played, and it creates really out of this world spiritual experience. And all other notes are related to this basic for marwa interval If we listen to classical performance of Marwa we can hear tanpura playing this unstable and irritating interval. So you are using four separate lines. Maybe it would be cool to dedicate one or two lines to electronic-tampura emualtion and dedicate it to only two notes tonic and seventh. So that they are constantly present in the mix and maybe octave appart or alterating to save keep the mix not so tense with nmore accent on tonic, maybe duplicate tonic octave down. I guess in electronic emulation this interval can become more harsh than in the tanpura. 2018-07-11 15:34 GMT+03:00 Dave Seidel <dave.seidel@gmail.com>:

Bravo, Dave. Beautiful, as always! Am I hearing little glitches from time to time that represent xruns from the Rpi3, though? On Wed, Jul 11, 2018 at 7:34 AM, Dave Seidel <dave.seidel@gmail.com> wrote:

Thanks for your comments. There are two layers here: the first (the loop I establish at the beginning) is more-or-less the structural analogue of a tamboura drone, and is based on Sa (C) and Dha (A), which I've seen documented as common for Marwa, and I think is a good way to express the tonal ambiguity of the scale. There is no fifth at all, in either layer. The other layer is a series of dyads I play over the initial loop, and here I'm playing only chords that specifically *don't* include Sa -- until the end of the entire sequence, when I finally play Sa and remain there. So I was definitely trying to respect the avoidance of Sa in the melodic/harmonic layer until the end of a phrase as an important aspect of Marwa. In this piece it's one long phrase, so Sa only appears at the end. - Dave On Wed, Jul 11, 2018 at 11:26 AM Anton Kholomiov <anton.kholomiov@gmail.com> wrote:

Hi Aaron, No xruns, the only glitches in the opening loop are deliberate, and result from routing one channel of the sound through a Digitech FreqOut pedal, creates artificial "feedback" based on harmonics in the input. In this case, I have it set to do the Sub (as in subharmonic) setting, which attempts to generate a tone one octave below whatever it thinks is the fundamental. There's a threshold setting as well, so you have some control over how the generated tone kicks in, and I was going for a slightly glitchy effect here to contrast the smoother top layer. The opening loop also uses a Red Panda Particle to get a slightly "wobbly" layer made from a mixture of forward and reverse granular delay. The Pisound is outputting at 48KHz, and I've tweaked the code and settings a fair amount to keep it as smooth as possible. - Dave On Wed, Jul 11, 2018 at 3:33 PM Aaron Krister Johnson <akjmicro@gmail.com> wrote:
