Developer Dan Trueman has introduced bitKlavier – a digital prepared piano for iOS.
Like the prepared piano, the “prepared digital piano” feels just like a piano under the hands and often sounds like one, but it is full of surprises. Instead of bolts and screws stuck between the piano strings, virtual machines of various sorts adorn the virtual strings of the digital piano, transforming it into an instrument that pushes back, sometimes like a metronome, other times like a recording played backwards.
The virtual strings also tighten and loosen on the fly, dynamically tuning in response to what is played.
Here is the official video intro:
There are a range of “preparations,” including:
- Synchronic: “metronomes” of various sorts that respond to your playing.
- Nostalgic: reverse piano, synced to the synchronic preparations or driven by the length of the notes that you play.
- Tuning: various tuning systems, including some that change under your hands as you play.
- Direct: muted notes, so they don’t sound when you play, but their preparations activate; surprisingly useful!
These preparations can change under your hands in various ways. For instance, in the Tempo pane you can make the Synchronic metronomes follow the tempo of your own playing, and in the Preset pane you can make specific notes completely change the preparations to a different preset.
