Alexandernaut, creator of Arpeggionome, has introduced a new iPad app, Fugue Machine that they describe as ‘Bach in a box’
Fugue Machine is a tool inspired by composition techniques used in classical music, from Baroque to Serialism and Minimalism. The developer’s goal was to create a tool that lets you manipulate a melody’s speed, direction, and pitch, as well as play multiple variations of the melody simultaneously.
Fugue Machine implements this by reimagining one of the basic elements of music sequencers: the piano roll.
The Multi-Playhead Piano Roll
Alexandernaut calls Fugue machine ‘the world’s first multi-playhead piano roll’.
It lets you create a musical sequence and play it back with up to four playheads at once — with control over each playback head’s speed, direction, and pitch.
Here’s a video intro:
Here’s an example that uses Bach as the starting point:
- Style: play the sequence forward, reverse, forward-reverse, or reverse-forward
- Tempo: speed of of the playhead relative to master tempo.
- Start: step at which playhead starts playing the sequence.
- Invert Switch: if enabled, the sequence will be harmonically inverted. In other words, the highest pitch becomes the lowest pitch, and the lowest pitch becomes the highest pitch.
- Octave: transpose up and down by octaves.
- Pitch: transpose up and down by single notes.
- Velocity: loudness range of each playhead.
- Fugure Machine lets you control other iPad music apps, hardware MIDI devices, and computer software
- Shift-slider lets you transpose the entire sequence up-and-down
Fugue Machine is available for US $9.99 in the App Store.
