Digitising a 3 Manual Compton-Makin Organ: Part 5 - Audio and software

Final bits is connecting up the MIDI control to something that can actually output Organ sounds. For this I used a ThinkCentre mounted under the front using a healthy amount of 3M velcro: This then connects via USB to the MIOS32 MidiBox, and USB, originally to a MOTU 828mkIII sound

Digitising a 3 Manual Compton-Makin Organ: Part 4 - Other minor things

The other minor repairs that needed to be done to be properly playable and servicable. One of the main issues was that the center manual couldn't be played properly - the keys only sat a few mm above the felt rest and therefore wouldn't activate properly when pressed down. In

Digitising a 3 Manual Compton-Makin Organ: Part 3 - Replacing the electronics

AKA the fun part! I actually did this work almost 2 years ago now, but I never got round to writing it up until now! I wanted everything to be controlled over MIDI, which is pretty much the standard way to communicate key presses, as well as stop changes and

LXC User/Group Pass-through

Let's say you have a user and/or group you'd like to pass through into an LXC container. Simply add the userid and/or groupid to the respective subuid/subgid files located in /etc/subuid and /etc/subgid in the form root::1 (why the thing is root, don't ask

Digitising a 3 Manual Compton-Makin Organ: Part 2 - Initial Reverse-Engineering

So, after having moved the organ into its temporary (hah) home, it was time to look through the bits that were in the organ. The manuals connected to this board with, is that really what it looks like, a MIDI connector! Well, digitising that part of the organ is already

Digitising a 3 Manual Compton-Makin Organ: Part 1 - The Move

So, being an avid user of eBay and also playing the organ, I did the next natural thing and bought an organ console (not one with real pipes mind you - I don't have space for anything like that!). It was listed as not working, but otherwise in good condition.

Boilerplate systemd Service

Making linked virtual machines in vSphere 6.7

Making linked virtual machines allows multiple (possible infinite) VMs to share the same boot disk with only changes being stored seperately, giving huge benefits to storage. For some reason, VMWare decided that this shouldn't be a nice easy UI button to do. Use the script here (https://github.com/pddenhar/

Setting up the Kramer Audio Matrix Part 1

I managed to pick up a 16x16 audio matrix switcher (VS-2216) from ebay for pretty cheap. But now we need a way of controlling it! It has a RS232 interface which should be pretty simple to interface with. The protocol for all (as far as I am aware) Kramer products

Fairly recently I bought an Icom IC7000 radio. It's a great small radio with up to 100W of RF power output. However, the interface cable that it came with (called a Icom Data Mode Cable cable), has two cables for audio and a USB serial connection, great! However, looking at

Problems with UDP streams and windows 10

The Problem Since windows 10 (anniversary addition I believe), windows changed how network adapter prioritisations are done. This gives rise to the problem of trying to play a udp stream but it actually binding to the wrong interface (seemingly even if all other adapters are disabled) and producing no output.
