MIDISID Monday, General MIDI mode with a wacky solo

This week has mostly been spent working on mono mode but it's not yet ready for a demo. Components have arrived for the next hardware version (which is going to look great) but the boards haven't turned up yet.

So the update this week will consist of a piece of music I put together partly to demo MIDISID's General MIDI mode, and partly to have fun playing with a new instrument I've just put together. Rakits are a fab introduction to the world of modular synthesis, I love my baby8 and atari punk console. I had the good fortune to meet the 'MakeaRakit team' at emfcamp a couple of weeks ago and couldn't resist buying some more kits.


What attracted me to the Cracklebox was partly the method of playing it and partly the unpredictability, which goes against my nature completely.  You have a little control but really don't know what you're going to get.

Something quirky and slightly sinister was required for a backing groove. A 3+3+2 (which has a waltz feel, sounds slightly off-kilter) fits 8 quavers and so would give the option of adding something sequenced using the baby8/APC (perhaps for another day). 

In the video you'll see that I started with some standard Logic software instruments, to try some instruments out and settle on a sound. The idea was to then play the music I'd recorded, as MIDI, into MIDISID and use its general MIDI mode. This mode assigns one MIDI channel to a SID voice, so in this case we can use up to 6 channels as we have 2 SIDs / 6 voices. (This meant copying the upper and lower notes of the accordion part into separate tracks/channels. If I'd left multiple notes on the same channel, it would have arped them which is good but not what I wanted in this case.)

I did a little work on the upright bass and accordion sounds in the MIDISID firmware. You simply make sure that whatever you're using to send the software sends a 'program change' message (from a choice of 127 varied instrument sounds). So in this mode there's no setting up to do with MIDISID, just switch on, put MIDI in and get the audio out. 

So without further ado, here's the (so far unnamed) music.

Building a Brachiograph

Image
 At Liverpool earlier this year, Andy Piper was demonstrating his brachiograph, or lolly-stick drawing robot arm. Ever since I first had my ZX81 I've been mildly curious about robotics but have never taken the plunge. More recently I've been looking at various plotter projects, even bookmarked a few. Seeing this one in real life and seeing how cheap and easy it was to build (and my boyfriend chucking some servos in my direction) finally tipped me over the edge.  This project turned out to be, as billed, the perfect gateway into robotics. It really is very simple to build and there are tutorials online, including from Andy himself . Thanks for all this Andy! Lots of hotglueing ensued. So far this has all been very robust.  To make the wiring neater, I made this little distribution board. First I screwed the Pi Zero down and found that I couldn't plug anything into it, so had to cut a little plinth for it. I'm not going to pretend that installing the software went without...

e-ther 2 - Announcement and full rundown of features

Image
I'd like to announce the new and improved e-ther 2. This information is available in video form here . If you're not familiar with e-ther, then it's a small theremin-like instrument with MIDI and audio out . At first glance the differences aren't obvious and indeed the big changes to the hardware are internal.  However, I hope you'll find the list of new features as exciting as I do.  Hardware-wise, I've put the microcontroller and DAC onto the main board.  Although this increases costs (for me, not for you), there are some big advantages. Besides looking more professional, the audio module is no longer a 'buy separately' optional extra. It's incorporated and the audio jack is just there if you want it.  The audio module used to fit below the board but with the audio capability now built-in, the profile is more compact. Most of the new features are down to firmware which means that a large proportion of what I'm calling 'e-ther 2' will be...

Enclosures for MIDISID

Image
 The default configuration for MIDISID  looks fine and is functional. I have fitted wooden cheeks to my own, which gives it a look and tilts the top forward, making it a little easier to use when you're sitting back from it. MIDISID was designed from the start with 'bring your own box' in mind. It's a modular design, the top and bottom parts are easily separated and connect with a 4-way jst-sh cable. In my head I saw it being used in a sloping-top case. Paul of Bad Dog Designs has come up with a different solution. It achieves the same goal - tipping the controls and screen forward. It's a 3D print in two parts. It takes zero effort to fit - MIDISID just drops in. I don't know whether he has made the design files public but  please contact him  if you're interested. Update Nov '23 The current version of MIDISID is now larger, has a tilted front and custom side supports: Owners are still being creative with enclosures. Here's a beautiful one from  @k...
