RESET The Reset terminal is designed to have essentially the same trip voltage as the standard bipolar 555/556, i.e., 0.6V to 0.7V. At all supply voltages it represents an extremely high input impedance. The mode of operation of the Reset function is, however, much improved over the standard bipolar...

As for the hardware, I still have to add one connector (a gate/trigger input, the center connector) and some additional programming is required, but this is the way I use my modules in my synth.
I'm not commercially working on modules, just for fun...

Tadaaaa

Several reasons: first it’s reel to reel, second it’s small and last but not least: I got it for free... But any quad dac will do. What I am building here is a quadrature LFO, four outputs all 90 degrees shifted and the idea is that you can choose 4 different wave forms for each output. I am playing...

This is the schematic, I’m working on the software.
Soon a short demo.

It´s the visual representation of two of the four outputs of a module I´m designing.
More later...

Sure: viewtopic.php?f=17&t=240630

But the latest mods are not added, will do that later this weekend.

Ok, cool, please let me / us know

DONE!

What I forgot to mention was my unusual approach to modular: I usually design the modules myself and they almost all contain an Arduino, being a nano or stm32 Blue pill.
Nowadays my panels are 3d printed.

That first peak can also be caused by moist (speculating...) as we all know that moisture conducts electricity and when your synth warms up, the moist evaporates (magically disappears)....

I have always worked with electronics as my daily job, but in 2015 (age about 60 years) I have built my first (not modular) synthesizer consisting of two sine-, tri-, square-wave generators built around an AD9833 dds chips and controlled by an Arduino Nano, a dual adsr generator built around a dual ...

Due to limitations of the maximum clock frequency combined with the 1024 step delay, the shortest delay is about 5msec. And since the clock frequency is variable (by knob and cv) there will always at some point(s) in time be cancellation and amplification of the feedback signal if the input signal i...

Thanks! Yes I decided to incorporate an attenuverter for feedback and it turned out really nice, especially with sounds that doesn’t change much in frequency like the bassdrum sound used in the clip.
Thanks for the feedback (no pun intended ) and a happy new year to you to!

I have had a zip-drive but nothing but trouble with the d*mn thing.
So many times a disk would go bad....I’d never trust it with important data!

I’ve built a six channel mono in, stereo out mixer with two pots per channel, one for volume and one for panning plus a out volume potmeter.
Eurorack format.

Who cares it’s out of fashion? I like it a lot!

For me a good drone holds a surprise, there is tension and an expectation to the unknown.
So white, pink, blue or what ever color noise could be called a drone, but there is nothing in it to hold my attention, what a good drone can!
