Hi,
thanks for the info! I'll try it.
yes studing and working ... a lot of ideas but no time.
I did no circuitbending and 8bit microcontroller stuff for a while...
It's also that prob with beginning things and comming to the conclusion that
a similar thing is on the market. Mostly buying that thing is cheaper than DIY.
(like the SK-MIDI as it is available as an working kit
But my intention is generating 8bit lofi audio with cheap microcontrollers.
Emulating circuitbent stuff for example
- most bends affect the adressing of a stored sample
which can easily done with a uC and little extra RAM (like the SKs)
bending is done in software externally controlled...
or Different sequencers
Klee Sequencer
The Muse
, "GameOfLife / Cellular Automata" and all the Chaos algorithm stuff
http://ultravires.net/ensyns.html and
http://www.noyzelab.com/research/research.htmland so on ...
My goal is an easy and cheap modular system controlled by a master unit.
All modules (slaves) are controlled by the main unit (microcontroller with pc interface)
over i2c bus (2-wire bus) which is >10 times faster than midi and you don't need that In/Out/Thru garbage.
Since only two wires are needed. 127 Devices can theoretically be controlled.
I2C is implemented in the most uC with baudrates up to 1Mbit/s. (and I don't like MIDI)
The Main Unit can act as a stupid PC->I2C converter or as a stand alone master controller.
MIDI -> I2C is possible, too. A touchscreen (320x240) acts as an human user interface
like the "Lemur" or the "Fairlight CMI" (but all cheap and easy with 8bit microcontrollers)
The modules connected to the I2C bus can be everything..
- a input device (controllers, switches, pots, sensors ...)
- a output device (I2C controlled bending, analog CV/Gate, DIN Sync etc)
- Filter-, Synth-, Effect- Modules like on all the common analog modular systems (but digitally controlled)
Circuitbending can be done with Analog Demultiplexers from the 4000-Series like the
http://www.ee.washington.edu/stores/DataSheets/cd4000/cd4051.pdfor 4097 (2x4051) ... 4066 (4 switches)
OR "digital potentiometers"
controlled by a microcontroller which is controlled by the master unit.
RetroTechnologies from the past with new components. Most old things where very intuitional.
... a long way to go
... ok that's not real circuitbending, I know ...
but can make it much more controllable and comfortable
