Mouthpiece works! Beatjazz controller is now at version one.
Over the last week or so I have worked on a new mouthpiece. I needed something designed specifically for the nature of this systems interfacing concept; a mouthpiece that would allow lip pressure to modify parameters in a fashion similar to a woodwind reed.
on acoustic woodwind instruments, the reed vibrates and it is this vibration that generates the sound that is projected into the horn part of the instrument where closing and opening sequences of holes (keys) create sound that are tuned to specific pitches. The pitch of the vibration between the reed and the mouthpiece is controlled by how hard the player bites down onto the reed while blowing; less bite results in a lower pitch and more bite results in a higher pitch, in some cases jumping to a completely different set of notes when done in conjunction with breath pressure.
As I mentioned in my last post, two things that hindered my progress with lip-sensing mouthpieces were spit and design. I have had a kick with using an fsr as a lip sensor because if its ease of integration and low cost. But it does not like spit so the last few prototype mouthpieces destroyed the fsr within minutes because of my faulty designs. Enter 3d printing!
I was able to design the mouthpiece in a way that makes it very hard to get spitty, even though, technically, part of the sensor is in my mouth. I did this by designing a flat "plug “that funnels all breath and associated humidity, into the tube with the sensor being completely blocked from contact with said stream. The plug extends to the bottom of the mouthpiece as well. Just behind the plug is a reed-like flat surface that my lip comes in contact with. This presses a raised, felt covered fsr-shaped platform directly onto the sensor. Felt is great because it is soft without being spongy so lip fluctuations are read pretty quickly.
So far, only one synth is receiving pitch bend commands but I seen that the other parameter controls I have assigned to lip are working properly! Yaaay!!!
This addition along with the new joy toggles, finally place the beatjazz control interface at a cautious version I! with this, I feel like the system is ready to be shared and duplicated so I will test its performance at the Elbjazz fest on Saturday and test the other controllers in the coming week and if all is good, I will ship them out to contributors, with the addendum that the software progression will be an ongoing thing and these will ship with the current control software, with the full suite software to come later.
As well, the new mouthpiece and joy toggles are ready for contributors that took the beatjazz perk that included those parts.
This weekend I will have my debut feature Jazz festival performance at the Elbjazz Festival in Hamburg. I am optimistic that it will be amazing. The following week, I will be in London (May 30) for the Lost Lectures and in Nantes, France (May 31st) at Stereolux then back to London for a bit of club bidness. So any hiccups in the design will be glaringly obvious in the very near term. Holla...
