Ricard's GitHub index

My GitHub page has various original software and forks that I've been working on from time to time. The most interesting ones are:

Original Software

• Xtor - the extensible MIDI synthesizer editor. Inspired by a simple generic CC control application I saw for Linux once, I made a Linux MIDI synth editor based on Gnome Glade. Currently only implemented for the Waldorf Blofeld synthesizer, it's a nice little editor, with multi part support. Unfortunately, the UI has become so complex that it outgrew the boundaries of the Glade editor, so the .glade control file can now only be edited in a text editor and is thus largely unmanageble.
• d8bup - a Linux command line tool for use primarily to process backup and restore files sent to and received from the Korg D8 digital recording studio via the S/PDIF interface. When upgrading from my trusty old Korg D8 to Ardour in Linux, I wrote a small test-driven utility for processing D8 backup files, which can do things like display the name of the song in question.
• MMT-8 utils - a collection of utilities for the Alesis MMT-8 sequencer, including a librarian, pattern and song name extraction utilitiy, and utilities to covert between readable text and the MMT-8 internal binary format. Note that this was written a long time ago in Turbo C for a DOS PC which I used for MIDI work a while ago. Some work is needed to make this build on a more modern system.
• es12wav. This is a Linux utility for converting samples recorded on the Korg ES-1 to .wav file format. It basically is a rewritten reverse engineered version of Korg's own es2wav.exe program, done using the REC (Reverse Engineering Compiler) (I believe it was an earlier version of this.)
• ccubit - a simple Python utility for the Bitstream 3x MIDI controller, to create a sysex file for programming the unit from a text description file.

Forks

• ZynAddSubFX and Zest, the core synthesizer and separate UI application for the ZynAddSubFX cross-platform software synthesizer. These are my working repositories which I use when working on this project, so they usually just contain a couple of development branches, and temporary branches for upstream pull requests.
• zynthian-sys, zynthian-ui and zynthian-data contain my local branches when doing work on the Zynthian Linux-based Open Synth Platform. I've got the bleeding edge version of ZynAddSubFX running on my Zynthian, so I keep changes here which are needed to support the differences from the 3.0.5 version currently used in Zynthian, as well as using as a repository for sundry bug fixes and enhancements.
• Axoloti, software for the Axoloti patchable DIY DSP synth. The p6 branch adds buildtime support for running Axoloti on the Audiothingies P6 synthesizer, including modules for display and encoder support. This hasn't been updated in quite a while now. I had a long term plan for creating my own synthesizer using the Axoloti software platform, but implementing a good user interface turned out to be a rather daunting task on this platform, which lessened my interest in finishing this. I did get into experimenting with some low-CPU DPW oscillators however, which turned out to have fewer aliasing artefacts and lower CPU usage than the BLEP based oscillators in the Axoloti code base.
• mios32 - the operating / application building system for the MIDIbox project. With support for the Audiothingies P6 hardware, so that MIDIbox can run in that environment. As an experiment, I ported the Goom synthesizer, so that it can run on the Audiothingies P6 with parameter editing using the display, buttons and encoders. Lost interest in it, as it wasn't a very good synth implementation. Another project is a simple MIDI processor which runs on a STM32F4 DISC1 STM32F407 DISCOVERY board (which is the default board for MIDIbox applications using the STM32F4 port of the MIDIbox project), which adds MIDI Program Change controlled octave shift and key split functionality. I use this together with a Roland Alpha Juno-2 which I use as a master keyboard, to get quick octave shift functionality and split capability.
• p600fw - a fork of the GliGli CPU and software upgrade for the Sequential Prophet 600 synthesizer, while I was doing some minor contributions to the project, including some bugfixes to the key assignment and implementation of the step sequencer. Has not been updated in quite a while. A friend of mine had a GliGli-modded Prophet 600 for a while and made good use of the fixes and additions I made, but he eventually sold it and I haven't brought myself to buying one for my own use. I honestly don't know how much of my contributions are still in the code.
• Edisyn - a Java-based editor for the Waldorf Blofeld synthesizer. Haven't updated this in a while, It's a nice editor for the Blofeld, and I think I contributed some minor patches at the time.
