More resonant filter nonsense:
This is another Octave based DSP prototype of pinging resonant filters tuned to different frequencies - in this case it’s a bunch of various four note triads.
The goal here is to eventually get this onto a µC like a blackpill or daisy-seed and put it behind a module - but like all my projects its baby steps…
Cheers
a 4-note triad seems a bit strange to me, like a pentagram with 6 spades 
, a 5-legged quadruped … a bi-directional 3 direction etc… 
example, major triad : fundamental + perfect fifth + major third.
what did you mean by that? maybe add a seventh? (but it wouldn’t be a triad anymore), or did I miss something?
There’s an octagon house in Washington, DC. It has six sides.
Gangsta chords!
Got a bit jazzy with the terminology, should maybe just have said chords.
In any case, the major and minors are root, third, fifth and octave. Then there are the augmented and diminished - also includes the octave.
Plus the Jazz chords, major and minor and dominant seventh, major sixth and two sus chords.
I really put four notes in there to make writing the code to generate the inversions easier because I’m lazy like that.
Cheers
If in a chord there are roots + third + fifth + octave, it remains a triad with 3 sounds, the octave not being another note, so yes a 3 sounds triad but with 4 notes 
Hi. I did not have the time to build some new modules recently but I spent some time on portable cases.
Since I’m doing more and more shows I had to find a solution to have portable case that can fit in a car without breaking anything or even be transportable by train …
First I wanted to use a custom flight case service … but the result was way too expensive. So I bought a flight case dedicated to guitar pedals. I replaced the hinges by drawbolts to make the cover removable. And then I built this wooden structure to place the modules.
I still have to find a solution for the power. I don’t know if I stay on a Doepfer 100SSB (I’m happy with it but it’s an IEC connector and it’s huge …). I would like to try some “light” solution like Tip Top Audio uZeus.
that looks quite heavy for a portable case …
The wood I use is fir. Really, it’s not that heavy 
I will tell you the final weight once the power and the module inside.
Also, I prefer a little weight that will help the case to stay steady on stage 
Harder to steal too…
Fake News
to be serious: One of my children is turning 7 in a few weeks and she requested a fartbox. She gets my previous case, the fartbox plus her own mixer to connerct her stuff to and a cheap amp to pop some passive speakers. She allready got the rockstar/punk attitude, we’ll see about the talent
Schematic being mostly 4x of this
A planning of helping to prototype building process. A 5x5.5cm circuit board to expose pins of TL074 and have components easily put there. I could make the basic op-amp -parts of prototypes there and know that they work, and focus on the harder parts and not needing to check if the input buffer or something is soldered correctly. I made this for myself, so the layout may be a mess, but if I get these manufactured, getting 100 of these instead of 20 doesn’t have that much of a cost difference. Would anyone be interested of buying these for like 1€ per piece?
hahahaha thats excellent
I don’t know what’s going on here but I fricken like it.
Finally getting close to finishing this behemoth of a schematic… the SS2130 VCO, definitely the most intricate design I’ve done so far.
That’s so many opamp cells… is that 8 TL074s?!
4x TL074, 4x TL072, 1x MCP6004, 1x MCP6002… 30 cells in total 
Granted, I still have to do some optimisation, get rid of some, combine others. But yeahh, there’s a lot of functionality in this thing, VCO, sine shaper, suboscillator, 5 VCAs and a mixer, gotta take some opamps
