On this page, we’ll explore some odds and ends that can make the flute more interesting.






As in the pipe, growling is when the flute player interrupts the air pressure into the instrument at a fast rate, typically 15 to 30 Hz.


We’ll add growling to the flute in the same way we added it to the pipe:  by modulating the incoming air pressure.  The patch is below.  The LFO controls the rate, and the “Growl Amount” knob controls the amount.





Controlling amplitude with velocity


As in many patches, we’d like to modulate the amplitude with velocity.  Once again, clicks can be a problem on monophonic patches, so we’ll use the same trick we used on the pipe:  we’ll control the amplitude indirectly, and add a glide module to smooth out the clicks.  The patch is below.





Shortening the attack time


Sometimes, the attack time of the flute can seem too long.  Shortening the envelope generator’s attack time helps, but what is really needed is an extra “burst” of air into the flute.  Flute players themselves do this when “tonguing” a note.


We’ll use an additional attack/decay envelope generator to do this.  One caveat is that we don’t want this additional burst of air when slurring from note to note; we want it only when tonguing the first note in a phrase.


Here, the MonoKey module comes to the rescue.  One of its outputs is a gate that rises when the first key is pressed, and doesn’t fall until the last key is released.  Commonly used to trigger the percussion envelope on Hammond patches, we can use it here to avoid triggering our envelope while playing a legato phrase, or while trilling.


The patch is below.  Notice that the outputs of both envelope generators are sent to the jet driver.  Just for the heck of it, we’re using the pulsed noise technique to create our breath noise.





Improving embouchure control


It’s nice to be able to change the embouchure pitch and play overtones, but the overtones are difficult to lock onto.  It would be nice to have “dead zones” around them, so that they’re easier to find.


Below is a patch that does that.  It uses the 8-input multiplexer, with xfading turned on.  The output of the multiplexer adjusts the embouchure pitch.  The first two multiplexer inputs are unconnected, so they output zeros when selected.  The next two make the instrument jump up 12 semitones, to the 2nd harmonic.  The next two make the instrument jump up 19 semitones, to the 3rd harmonic.  The last two jump up 24 semitones, to the 4th harmonic.


The multiplexer’s xfading setting is turned on, so that transitions between the inputs are smooth.  Because identical input values are used for two consecutive inputs, useful “dead zones” are created between those inputs.
