Environmentally conscious art should not be advanced trough gatekeeping which judges individual artists for the technical solution they choose. Discussions about technical solutions are indirect routes for judging taste and not everyone has the opportunity to develop technically ethical taste. Guild about the energy which creative expression wastes should not hinder it. Everyone should be granted the opportunity to shed the burdens of the class they have been born to. This is why degrowth should effect the rich more then the poor. A request for Media Artist I wrote 2012 (I think this company offers a solution which is based on RasPi).
My Bastl microGranny 2.5 kit arrived. The assembly looks very challenging.
I succeeded in installing Pure Data (Pd) on my RasPi 3 and I’ve been playing with Automatonism 1.1. It works great and even got my Novation Circuit to work with it! Automatonism is a virtual modular audio system. It’s the successor of XODULAR (both systems have been written by Johan Eriksson). Automatonism is a great way to learn both Pd and audio synthesis.
While fiddling with Pd I figured our that I can use it to write a midi CC modulator/translator which will change the CCs Novation Circuit sends over midi into CCs which the microGranny understands. The Circuit synths CC values can be automated using the inbuilt sequencer. The combination should make for very interesting results. Much like some Elektron sequencers with parameter locks. I guess I could run a Raspberry Pi Nano which only works as a Pd midi CC modulator/translator: ctlin (isolate CC) -> values -> ctlout (to desired CC). Or something.
I’ll try to learn Pd by making a midi clock input for Automatonism. Also discovered the Piz MIDI plugin collection which seems very useful. The plugins have been updated earlier this year. By the looks of it midiForceToKey can be used to make microtonal stuff.
A great resource for learning about granular synthesis.
- J.a.g.s by limulo.net is a pd patch I could test with my RasPi
- Logic X has an inbuilt granular synthesizer (good tutorial)
- Clouds by Rajmil Fischman is also very complex (and free)
Also found Automatonism by Johan Eriksson a modular audio environment which works inside pd. Wonder if it can run on RasPi?
Judging from Erikssons example it appears that nowadays electronic artist have make their own soft-/ hardware to market/facilitate/fund their creative careers. Mark Verbos in another excellent example (see his interview for details). Artists build their income by creating and sharing tools/instruments they use to make their art. This means that tools are currently more significant then artworks.

Notes to self: Hammeradio operates with scheduled scripts. Access schedules with
crontab -e, look for scripts in /home/pi/Desktop/. The entry
@reboot /home/pi/Desktop/startupfm.sh launches
sudo arecord -fS16_LE -r 22050 -Dplughw:1,0 -c 1 - | sudo /home/pi/PiFmRds/src/pi_fm_rds -audio - -rt Hammeradio & on startup. PiFmRds begins broadcasting at 107.9 MHz. The contab entry
0 */4 * * * /home/pi/Desktop/akustamatashutdown.sh waits for four hours before it runs the script (
sudo shutdown). With
top you can see active processes. PiFmRds shows ~24.5% CPU and arecord ~4.6%.
vcgencmd measure_temp shows a steady 49.4°C temperature.
Making the “Hammeradio” launch FM broadcast by scheduling tasks with cron.
@reboot /home/pi/Desktop/startupfm.sh works well. It launches
sudo arecord -fS16_LE -r 22050 -Dplughw:1,0 -c 1 - | sudo /home/pi/PiFmRds/src/pi_fm_rds -audio - -rt Hammeradio & I’ll also schedule a daily power off cycle for the device. I’ll set it to work during gallery open hours 14:00 to 18:00 (with a Lunch break in the middle). Found an old amplifier circuit I build (while learning to solder to make the WSG) and I’ll test it with the piezo mic I have handy (It would save the iRig pre-amp I bought).
