This is what I've been obsessed with for the last few weeks. It's taken a while but I now have a working Haxocorder - a custom hacked Haxophone. I'm still refining but it's now a usable electronic wind instrument for a recorder player.

I've been having fun with my RC2014 Orton 3C, toggling in an etch-a-sketch program that uses my dual analogue input module and 8x8 LED matrix module:

The audio in this video is a little soft, so be grateful for small mercies. I have been working on a secret project, which is to put the ZX Spectrum BEEP code into ROM for the #RC2014 Orton 3C. By coincidence, I found that I was using a tune from Star Wars on the day before Star Wars Day and so I went for it today and made a complete medley. (Yes my Orton 3C is fitted with the 3C-PO shim...) I wrote my first blog post about this before I'd added the ROM, so it was a pretty pure 3-chip 'all code and data toggled in' project at that point. I couldn't have done this today without using the ROM though! https://youtu.be/9E0ny1_zdTI Blog post: https://newstuffforoldstuff.blogspot.com/2026/04/using-speccy-beep-routine-and-beeper.html

Also in this week's news, I've received and had a cup of coffee with the new Public Domain SID.

@edbrindley@mastodon.social I can't tell you how grateful I am for this. Thank you. It's fun to listen to the examples, and this is my first go at making music for FM synthesis:

@robertprice Yes, total credit to HLD for going into a ridiculous amount of detail about that routine. It seems appropriate to use the Speccy routine and the rawness of this makes me very happy, it's just using a transistor on an address line. I've been curious about this ever since Spencer started talking about the 3C and explained the ingenious way that the serial works. We've been actively working on adding this to the rom image on Codeberg. I did see Ben hooking up a SID chip to his breadboard computer, is that the one?

I've been using this kind of stuff recently and have really enjoyed putting some together myself. This is part of my 'falling asleep music' endeavours but is also a development of the MIDIPan / MIDISID improv I did last week.
Lie back and enjoy it, as Tommy used to say.

Today I discovered that Music Mouse was ported to #Amiga and ST. Here's me fooling around with it for the first time on real hardware.

@concretedog@mastodon.social Thanks CD! All credit to Javier for the Haxophone, I've just moved the keys around a bit and tweaked the software.

@dec_hl@mastodon.social Thank you, all credit to Javier who designed the Haxocorder. Keyboard keys work really well and suit me much better than capacitive touch and it plays really well.

@robertprice Ah no, I hadn't seen that, thanks! (Poking a peripheral chip so that it makes sound without tying up the CPU? That's crazy!)

@rc2014 I bet I could make it do a passable impression of R2-D2 as well!
