Summer of Synth-DIY: Week 14

Last post was late, and this one is a few hours early, ’cause I HAVE GOOD NEWS.

Sound Lab progress: A good 2/3 of the front panel is mounted on the panel:

Of course, it turns out all the SPDT switches I got from Futurlec aren’t really. Grumble. Ordered more (from Goldmine this time).

Arduino MIDI Sequencer: IT’S WORKING (the good news). So now, it’s at the point it was at during my presentation at Notacon, except actually functional (and less prone to breaking – the previous internals were horrid – this is much cleaner, permanent, and stable.)
Here – have a listen: seqtest.mp3 (controlling U-NO-62)
It still looks like this on the outside:
Arduino MIDI sequencer V1

However, the on/off switch is currently removed, and will be replaced by a start/stop button.

Also, at Playshop this week, we did the MS-20 pseudo Ring modulator (with a CD4011, easy!), and the milkcrate/little scale “sea moss sequencer”. I think I’m going to reimplement that with pots instead of the resistor ladder, and maybe make it switchable between internal clock and external clock (so I could, say, sync it with the Arduino sequencer!) Going to have to figure out an enclosure – half not wanting to use another cigar box, but they’re so darn cheap ($1/each)!

Also also looking at slowly working on some ‘big boy’ modules, though there are a LOT of design considerations I’d have to make (format, enclosure/rack, etc.). Cigar boxes won’t work for this 😉 I think my studio will need a lot of cleanout before any real motion on that front starts. Stay tuned.

No idea when I’ll actually get to anything this week, though. Schedules are looking very busy all the way through the weekend.
