This Hurdy Gurdy Works As A MIDI Controller
In this video from musician Barnaby Walters, we get a demonstration of a Hurdy Gurdy/MIDI controller hybrid created by Walters himself.
0:22 Technique: Pitch-shifting Polyphony
- Gurdy MIDI and Audio → Apogee ONE → Macbook running a puredata patch
Monophonic acoustic gurdy signal is pitch-shifted down in real time to play chords and harmonies. Chords and intervals on the keyboard can also be used to pitch-shift the trompette signal (0:55) or the drones. Inspired by an idea from Sébastien Tron.
1:18 Technique: Expressive MIDI Controller
- Hurdy Gurdy MIDI → DIY Hybrid Poly Synth based off Mutable Instruments Ambika
The keyboard and wheel sensors send MIDI note, expression and polyphonic aftertouch messages to a polyphonic synthesizer. In this case a split keyboard effect is used to play two sounds.
1:36 Technique: Layered Acoustic and Electronic Sound
- Hurdy Gurdy Acoustic audio, Gurdy MIDI → DIY Hybrid Poly Synth based off Mutable Instruments Ambika
- The acoustic string plays a melody, the bottom half of the keyboard controls a synthesizer with a long release for subtle held chords
- Using trompette technique can send MIDI messages, used here to play synthesized percussion on an Ambika voice assigned to MIDI channel 10, whilst the keyboard plays chords.
- Acoustic trompette and melody string sound layered over subtle polyphonic synthesized chords
