Säckpipa is a simple mouth-blown Swedish bagpipe app featuring a single chanter and drone, producing a lovely and haunting sound. The app allows users to play the Säckpipa on-screen or with a hardware MIDI chanter or keyboard, serving as a MIDI sound module for a MIDI file player through CoreMIDI.

Touch any key to start the chanter playing continuously, mimicking the real Säckpipa experience. Play melodies by touching the keys and toggle the drone on and off by tapping the drone image. Users can adjust the instrument's root key in D, transpose it in semitone increments, and fine-tune it within a range of +/- 50 cents in one cent increments.
