bismark swipestrings is a musical instrument application with an interface similar to the fingerboard of a fretless guitar. Leveraging the fantastic multi-touch screen of the renowned iPhone and iPad, it allows you to express subtle pitch variations in real time, closely resembling the fretless guitar interface. With practice (of course, as everyone would need), this app enables you to create rich musical expressions comparable to playing a real instrument.

It is compatible with CoreMIDI, Audiobus, and Inter-App Audio, allowing seamless integration and cooperation with other applications that support the same standards.

The app comes with a single built-in sound. However, you can expand the range of sounds by sending MIDI data to other CoreMIDI-compatible apps like bs-16i.

The sound source that receives MIDI from this app assumes the following specifications:
・MIDI Channels: 1 to 6 (assigned to strings 1 to 6, respectively)
・Each MIDI Channel operates in Mono mode.
・Each MIDI Channel operates with Pitch Bend Sense = 12 semitones.
