In the early 80s I had the honour of working with Peter Vogel’s FAIRLIGHT company in advising and testing the world’s first Pitch to MIDI converter; the VoiceTracker (VT). The unit is quite large (approx. 30com wide) and works best with a display screen. Latency for monophonic conversion was dependent upon the internal settings, which determined how many “iterations” of the wave-cycle was analysed before deciding on the pitch, then spitting that out to 8bit MIDI. The fastest I got the unit to track with accuracy was having it set to 3 iterations, with the latency for A440 being approx. 9ms. This was very laggy by today’s standards but in 1983 it was a sensation. I’d open the show with a solo trumpet, but the audience would also hear my Yamaha DX7 synth “playing along with me.” Saxophonist Brandford Marsalis also bought one when he was in AU after I introduced the VoiceTracker to him. Unsure about his unit, but I still have mine and I’ll never get rid of it; it’s an Australian Legend in audio design and technology.
Today I bought a Sonuus G2M unit and thought readers would appreciate the differences over nearly 40 years. Oh, the price? The VT was over $3000 back then (although Fairlight did give me a good deal). The G2M was a little over $100.
