Hello world, its been some months since we have completed anything in the realm of homemade electronics. Basically we have had our world turned upside down lately, I am now living in a whole other country working at a new job and trying to do as much Fotosis related work as possible on my off time when I come back to Lyon on the weekends.
This project was a custom order that challenged us to develop several new systems, most notable a sample and hold circuit and a micro-controller based trigger pulse generating system.
There are too many controls to list individually and descriptions would be difficult because I don't think it would be possible to find similar controls on another system to compare them to. This will probably be the last time I try to make an all in one unit this complex due to the time it took to develop build, test and debug the various circuits and programs that it contains. I feel in the future it would be better to build each of the systems individually and house them in separate enclosures that could be attached to some sort of board that gives them power etc.
Anyway here it is in action Fotosis No. 007...
There are still two more sections to complete, a CV interpretation module that will take in a control voltage and convert it to trigger pulses that can be used with the trigger pulse system and also a rocker pedal that will control the pitch of the oscillators as well as several other functions.
The sound range from more conventional synth noises to full on noise as well as different patterns of beeps and tones created by the trigger pulse generator. It would be the type of instrument ideally suited to someone wishing to create strange little samples for use on their tracks or it could be used live as a bizarre noise generating unit.
So essentially I am not going to go into details regarding the technical elements because there are just too many, so please just bask in the glory of this weird and interesting creation.
