MOTM

I was ever so slighty able to use the Yamaha BC3 breath controller with the 
MOTM without using Midi, after I connected a stack of cable 
adapters/converters and some aligator clips, but unfortunately I couldn't get 
enough range out of it to do anymore than allow me to alter LFO speed a 
slight amount.  I measured oddball voltages like +5 and -8 going into the 
breath controller.  Blowing into the thing caused a voltage to drop, but 
that's where it gets confusing.  There was a change in voltage on both the 
tip and the ring of the connector.  The one with the biggest change which is 
what I thought I should use, didn't like it when I connected the MOTM to it.  
I had to use the other one.  It looks like it needs some amplification to use 
it this way.  If anybody has done this let us know.  Or if anybody knows of a 
breath controller that doesn't need Midi, please also let us know.

As a result, a somewhat flute like sound I patched up to use the BC3 without 
Midi, ended up not using the breath controller for anything more than a very 
slight change in tremelo rate.  But since I twice had a discussion with a 
Synth.com owner in the past about synthesizing flutes, I put it up for him 
anyway.  It's at the link below.  Again, it sounds muffled and horrible 
through my computer speakers.  It needs headphones or bright clear speakers 
to the point where you will be annoyed by the loud buzzing sound that got 
introduced from somewhere.  Note, it's played in realtime on a split keyboard 
with Piano on the lower half and MOTM on the upper half.

There used to be a lot of information on this.  Try checking out this info:

I think I've got some circuits for it somewhere.  There are some cool 
semiconductors that are pressure sensors, and you can hook up tubing to them 
and get proportionate control voltages from the sensors.  I believe National 
Semiconductor, among others, make them.

The Steiner Master's Touch has "breath" and "bite" tubes along with a touch pad and
a filter.  I just found one but it needs some work so I can't provide a good review
just yet.

I have one of these running with my MOTM, and I haven't had time to get 
alot out of it other than a groovy diggery-do type sound.
It has the following features:
For running audio it has filtered mixed and unfiltered outs, withc if 
combined in a mixer allow you to blow open built in filter. There is a 
dj-style slider that allows you to mix between unfiltered and filtered 
output. The filter sounds like a high pass to me, but I could be wrong. 
It's very raspy shrill at times, based on the settings of the S.E.D. 
(no idea) and resonance slider
On the CV side of things it's more interesting.
Breath controll can be used to change the pitch of a VCO, blowing 
making it higher and inhaling making it lower.
The bite tube, sealed at one end, sends a "wah-wah" style modulation 
fequency that starts strong and slowly fades out. It can be applied to 
a vco or filter 9for the diggery-do), and the bite has a slider for the 
intensity of the effect.
There is also a touch pad (the "Touch" in Master's Touch) which sends a 
modulation frequency based on wiggling your finger back ond forth on 
the pad.

There are also trigger outs, set off by the breath tube, one for 
inhaling and one for exhaling.
Also, the sensitvity of the breath controll can be adjusted with a 
screwdriver.

That's a brief roundup. I can't say I've had any luck playing anything 
but the sickly sounding tune with it, but it's fun none the less.

Thanks for the info about other possible breath controller alternatives.  
Normally I wouldn't mind using Midi, but it ends up being quite coarse 
sounding.  Direct CV would be better.  I'll check out the info.
