My main work has been in two areas
These are actually really related, because once we have
- Synthesis Algorithms: Enhance our Palette of Sounds
- Controllers: Augment the Human Performer
a flexible, expressive, parametric algorithm for sound
synthesis, we want a controller. And once we have a
nifty new controller, we want better sound synthesis
algorithms to control. Other pages talk about synthesis.
This one talks about controllers.

We made a number of versions, including a valve-
trombone interface. (see below under Hirn Section for
prototype valve section with modifications ).
See papers on brass interfaces and
pitch detection with Morrill and Smith in the
I also worked some with
Ben Knapp on measuring
brass Lip-EMG (muscle tension) and using that for
The Hirn Wind Instrument Controller
Idea: Give as many degrees of freedom as possible to
a wind player,
hook it up to various synthesis algorithms
including physical models of wind instruments.
Did it really look like that wonderful drawing?
Of course not. Here's what prototype 1 really looked like,
along side its valved friend from the Cook/Morrill
Trumpet project (see above).

There were a number of attempts to make real-time controllers for
SPASM/Singer. Mostly based on MIDI fader boxes and few-to-many
mappings, such as a single MIDI controller for vocal effort
(combination of intensity, spectral features, and vibrato).
This figure shows the computer control panels, but each of
these were also controllable from one or more external MIDI
control numbers as well.

Q: What two things can
control breathing, pitch,
and articulation of
vowels and consonants??
A1: A Singer
A2: An Accordion!!
