PhiliZound Software’s Sequetron is a Windows MIDI sequencer with a twist:
- Sequetron is designed as a live instrument for hands-on use, played & controlled from the music keyboard. It runs from startup with no interaction, and converts even the simplest MIDI keyboard or device into a multi-track recording, playback & looping instrument.
- Sequetron has sequencer-like functions, but is different from other programs as it is controlled using series of music notes called command sequences. In Sequetron, there is no difference between commands and music – they are all sequences, hence the name… it can even control itself.
- Input can be any MIDI keyboard or device, and the output can be any MIDI device(s) such as synthesizers, drum machines, light displays etc.
- Sequences can be recorded in real-time or step-time, played back, looped and altered (channel, velocity, pitch, mute etc.), either individually or in any combination, but unlike hardware sequencers, there is no concept of ‘steps’, nor do the sequences have to be monophonic; any notes & chords can be used. They can also be saved to standard MIDI files for further processing by other programs.
- This hands-on ability to record, play & alter different length sequences starting at different times on-the-fly gives Sequetron an unusual syncopated feel, encouraging you to experiment with overlaying and controlling patterns; even the most basic 1, 2 or 3-note sequences can create something totally unexpected.
