    MIDITOR

    MIDI multi track song writing in an ASCII editor!

    MIDITOR is a command line compiler that takes ASCII edited music which can be in the style of drum or guitar tablature but with accuracy. MIDITOR is comparable to a sequencer. It turns any ASCII editor into a MIDI editor, for loops, sequencing and composing. Any MIDI message can be sent at specific times including patch changes, control changes.... Tracks and channels can be easily rendered in parallel and the powerful macro preprocessor handles the repetitious nature of music writing. Music is easily scored in any editor chromatically and then output as a MIDI file to quickly check and play the score on FluidSynth or Timidity for instance. Conventional style guitar and drum tab can be used, even conventional style notation using macros, or just one line of chromatic notation.

    MIDItrk

    Tracker-style pattern-based MIDI composer

    This tool enables you to create MIDI with tracker-style handling. The main difference to most of the contemporary trackers is that it gives orderlist/sequence for all tracks, so you can use one pattern anywhere without tedious copy/paste process, just by typing its number in the right place... NOTE: I left SourceForge for reasons not ethical to mention here. You can find me and my further work at these locations: http://hermit.sidrip.com http://csdb.dk/scener/?id=18806 https://github.com/hermitsoft/
