New year project : Sop-re.co-Phone

Writer: Min SongMin Song

Updated: Feb 27

I created a mini MIDI wind controller using the Artinoise re.corder as the foundation. I named as "Sop-Reco-Phone(Soprano saxophone + re.corder)." I enhanced it by adding a bite sensor, a pitch bend mechanism, and an extra MIDI function button, similar to modifications I've made on my other instruments. The instrument's body was produced using a 3D printer, and I incorporated a micro-Arduino chip with Bluetooth LE to provide additional MIDI features. The Artinoise re.corder boasts an excellent breath sensor, customizable fingering, and motion sensors.

I also enhanced the re.corder's octave and sharp/flat keys for improved accuracy and performance. One challenge was making the re.corder function with breath without direct contact on its lip sensor. However, I know how to trick the capacitive sensor. I attached conductive tape to the mouthpiece and connected it to the lip sensor.

I intend to upload a performance video showcasing this instrument on my YouTube channel soon. Stay tuned!

Update on 2/24/2025 : I upgraded my Sop-Reco-Phone by enhancing its design, with a particular focus on improving the Bluetooth MIDI functionality to extend its range. This instrument features a bite sensor, pitch bend capability, and an additional MIDI button for expanded control options.
