Analyzer for Files (AoF) is a tool to look into file contents, analyze the structure with installed plug-ins, and show the results with several split windows including converted data and a tree if successful. It was designed as a workbench with a core and plug-in extensions. It can handle the normal plain-text file and data, complex binaries supported with the corresponding plug-ins. What's more, the developers can deploy and release their own plug-ins according to the plug-in developing standard. The development site is https://bitbucket.org/cadappl/anafile.

MIDI Master Clock: Simple MIDI Song and Control Change Manager MIDI Master Clock is a lightweight, command-line utility for effortless MIDI device control and synchronization. It lets you define songs or cues in a simple text file, each with its own BPM and custom MIDI Control Change (CC) messages. What It Does: Reads Song Data: Configure song titles, BPM, and MIDI CCs (e.g., CC_ch0 10) in an easy-to-read data.txt file. Interactive Control: Select songs from a list, advance through your set, or quit, all from the command line. Automated MIDI Commands: When you select a song, MIDI Master Clock automatically sends: - All specified MIDI Control Changes (CCs), ideal for triggering effects or states. - MIDI Sync Commands (Stop, Song Position Pointer (0), Start) to prepare your devices. - Accurate MIDI Clock signals based on the song's BPM, keeping your gear perfectly in sync.

Nautic Radio Broadcast Console is a darkice (shoutcast / icecast source client available at http://darkice.org/ ) frontend, that allows you to play jingles (audio samples), capture a webcam images to send to an FTP, chat with listeners (through an external webchat site) and monitor your audio and system (cpu, network) The program is developed, and used in production, for www.nauticradio.net / www.beatsnbreaks.nl and targeted at relatively old computers running linux. However it is not tested on many platforms, nor guaranteed to be stable. Minimum system requirements: CPU: 3 GHz pentium 4 or higher (preferably 2+ GHz dualcore), Memory: 1GB RAM or more, Diskspace: 10MB plus enough to record broadcasts in mp3.
