I think you're looking for AudioChallenger (in sonata.cc.purdue.edu,  
in pub/next/submissions).  From the README file:

"Audio Challenger 1.0"  was the first ear-training software released  
for the NeXT computer and version 1.7 offers substantial  
improvements.

Audio Challenger randomly generates ascending  
and descending melodic and harmonic musical intervals which can be  
used in  
assisting music students in trying to improve their ability to  
aurally identify musical intervals.   Audio Challenger features  
real-time synthesis on the DSP (digital signal processing) chip of  
the NeXT computer which gives it the advantage of a more natural and  
"lively" musical timbre than ear-training programs that currently  
exist on other platforms.  Audio Challenger is released as FREEware  
to the internet archives by the researchers and students of DREAMS:   
Digital Research (in) Electro-Acoustic Music (at) Skidmore College.
