Did you use 2 arduinos (essentially using one per sequencer) each with its own screen and I/O? ---

like the color coding sections and simplified control labeling good idea . ---

Yes , that is correct. Seeing as the cost wasnt prohibitive, then I thought might as well build two at the same time. ---

My configuration is separate clock inputs , but from the same master clock source. I like to use a clock from trig out of from lmnc big button to progress a sequence ( less frenetic?) but basically they are synced yes. I,m pretty sure you could multi a single clock to each arduino though. ---

Managed to build my diode ladder VCF this afternoon. Have’t had much time to play with it, but I’m really happy with it, it shrieks like a banshee and it’s probably the module I worked hardest on - so I’m stoked with the results: I put up schematics, BOMS and kicad pcb files here: > **[jazamatronic/diode\_ladder\_vcf](https://github.com/jazamatronic/diode_ladder_vcf)** > > Contribute to jazamatronic/diode\_ladder\_vcf development by creating an account on GitHub.

I love your write up of the no-pcb version! Seems pretty inspiring to start twisting components and make something happen! Great work documenting the steps! ---

Sorry for the mix up, I’m still figuring out stuff here. It is a wild build with all those free-style components just hanging out there. Thanks for sharing the link and for your filter work, walking through your schematic now. ---

Hey, I found an old effect pcb from the time when I was still scratching my 6 strings. This is the dead astronaut’s “Chasm Reverb”, a really cool effect for long atmospheres and ambiant. It is composed of a BTDR-2H brick from accutronics (which is 3x pt2399). I have convert the circuit into an eurorack module: I adapted the input and output levels for use with my modular; the idea come from the “stompbox adapter module” by Ken Stone (CGS60 - Elby Design). Then I just used a simple 12v to 9v voltage regulator with 78l09.

I hope you have more fun with the Noise Toaster than I do with the Weird Sound Generator. It was my first “big” project and I thought I had a device that you can really control and use musically … was not the case … Greetings THOGRE ---

I designed a wavefolder. In the video its output is shown when input is sinewave amplitude modulated from about 0.5 V to 5 V peak-to-peak. I managed to design it so that it uses only four op-amps, a one TL074. I need to buy couple of trimpots to check some adjustments (like getting the fundamental signal a bit lower), but them I’ll post the schematic when it’s ready. ---
