Guitar direct to Pd on a computer: Essentially yes, just an audio interface. Crank up Pure Data and look in Preferences to select your interface from the audio inputs. Many current interfaces have guitar inputs that have a JFET buffer or something similar so signal is pretty good if you plug in...

The initial power-up for this build was totally silent until a voltage check found an open on FV-1 pin 13 and an open at the stomp. After addressing those, all FV-1 pins return voltages that look plausible according to my interpretation of the schematic. When Mix is counterclockwise, Volume...

Newborn?! You chose a very hard project! Even harder than soldering SMD!

One benefit i have found of using Pure Data with Terrarium is that i can route guitar signal straight into my computer and preview results without uploading a binary. That saves a ton of time. Maybe you could get that to work in the C workflow, but it doesn't seem trivial... ps. that brings up...

Updated the template's patch to be tremolo, so you can hear if it worked. The template works for me.

Closing the loop: my little package was quite the jetsetter.

That has got to be the greatest way to be proven wrong.

Bangkok to Cincinnati via Hong Kong in 16 hours. (assuming that DHL converted all times to a single time zone...) Now on hold in Cincinnati. A quick back-of-napkin says my piddly-ass order traveled at 880 km/hr. 🚀 Gramps: "I see the problem. It's America!"

Soo ... i wonder if there are some testers about. Here is the template repo I mentioned: https://github.com/rhaleblian/terrarium-puredaisy A test would be to clone this repo and follow the README steps to build the stand-in patch that's already there. Before you stab at it, take note of what...

In the Pd space i have had some success getting knobs to take, but not always. If i can find out reasons then that may help in general.

I like what @fxwiegand did with the `terrarium-stand` GitHub template for C patches https://forum.pedalpcb.com/threads/terrarium-stand-template-repository-for-terrarium.5725/ so i'm taking a stab at a Pd version. When it's sufficiently tested i'll point to it. The host setup for Pd is...

Adafruit https://www.adafruit.com/ carries a number of neato microcontrollers, connectors and interface devices and i buy some of their stuff. They can take a little while shipping from NYC but Mouser already has a lot of their products, often the ones of which Adafruit themselves have run...

Anecdote: Tayda is warning about holiday delays, but i placed an order last night, DHL reported it received 2 hours later. We'll see how this anecdote pans out... My previous slow-boat order 2 weeks ago took 7 days to SE USA. ps. @mjh36 at first i thought your avatar was Yngwie Malmsteen. He...

I found a good amount of outright broken things in the code in my Terrarium repo; I'm cleaning it up and will send a pull request to @PedalPCB for potential inclusion into the original Terrarium repo. If that happens, my repo above will be retired and eventually disappear.

There are a few modules available from vendors to go to and from effect pedal levels. Some synth geeks patch effects pedals into their signal chain. I'm using a solution from AI Synthesis: https://aisynthesis.com/product/ai006-eurorack-stomp-box-adapter/ They discuss various approaches here...

whoa @BuddytheReow that pot replacement improves things greatly. there's more even output, the distortion range is wider, and the warmer lower overdrive settings are also available at usable levels. thanks.

One fundamental note about the above, and anything Terrarium-related, is that resources for the Seed as provided by Electrosmith https://github.com/electro-smith are applicable, apart from subtle differences of the controls between Terrarium and Electrosmith Petal, which our admin has...

Ennio Morricone!

Cloned and built @fxwiegand 's reverb patch based on this template, builds and deploys smoothly. And sounds good.

I seem to have put what i had at the time here: https://github.com/yoyodyne-research/Terrarium/tree/rhaleblian It doesn't rehash the instructions for getting dependencies etc that exist in other places, but pointers to those could be more explicit. I'm sure a whole lot more isn't clear but some...
