This is a cool idea, but you can switch between major, minor, chromatic and pentatonic scales so the interval between notes changes depending on how many there are so having fixed clicks wouldn't work in that case.

I am very lucky in this regard, my partner is amazing indeed! Most of the work was at night, so I hopefully didn't disrupt her too much.

I've been reflecting on this a bit. I found it very useful to have a well-defined project and focus the learning time on things that are necessary for completing it. Having a background in coding was useful because I find you end up developing a knack for isolating parts of systems and figuring out how to work on small parts that end up fitting together.

I therefore focused initially on simply getting readings from a single potentiometer; if I could do that then I felt pretty confident I could read from four of them. If I could generate a midi message I was pretty confident I could send it to something that could read it etc.

When I started on the PCB design I had a simple circuit already so it was a case of translating that onto a board.

I didn't get too deep into any of the various parts but I found that it gave me a birds-eye view of the whole process and I now feel confident in isolating parts of them and 'zooming in' to them and refining them, building on the foundation I've developed.

Thank you!

I didn't know that was a thing - I'm going to look into it.

I trained as a classical guitarist, so I maintain some longer nails on my right hand :)

Thanks! Yes it's a little digital synth that receives MIDI.

That's what the drum machine module is for.

Thank you! Unfortunately I decided to save that feature for v2!

Hi, your mental model is essentially correct, though it took me a good few evenings over a couple of weeks to get the workflow down in fusion 360. The electronics retailer will usually have the footprint and 3d model available on the component page. You can then import it, define which pins you want connected to each other in the footprint and in the PCB editor you can drag the routes (wires) to connect them.

Printing is way cheaper than I initially thought it would be - I paid £35 or so, including delivery and 5 of them arrived in 5 days. You can get cheaper delivery though. Also most of that cost is shipping and the setup fee - the marginal cost for each additional PCB print in the order is on the order of low single digit dollars.

Tbh my circuit was fairly simple so I just took a bit of a chance (and some extra care wiring things up). I think there’s a subreddit where people give feedback though I haven’t submitted anything.

Yes exactly, it would be great to be able to sync the clocks so they all ‘just work’ together. And maybe also a module that gives all the other synth parameters for the more advanced user too. I say it’s for my daughter, but I actually would love this too.

Thanks, these are great! A link to some scans of David Foster Wallace’s annotations in the New Yorker piece too. For the curious: https://archive.ph/o/M2H3s/www.hrc.utexas.edu/press/releases...

Are there any collections of annotated pages from books belonging to well-known authors that have been made available online? I'd be interested to get some impression of how they engaged with the material, whatever it is.

Fiction: It by Stephen King

Non-Fiction: The Spy and the Traitor by Ben MacIntyre. It's about the KGB spy-turned-MI6 agent Oleg Gordievsky and reads like a thriller.
