Re: [motm] Quantizer

2005-01-16 by Richard Brewster

For quantizing applications the wavetable output is used as a control 
voltage.  In this mode the Miniwave is set to the 0-10V scale, which 
takes positive input voltages and puts out positive voltages.  A 
quantizer PROM has a table that translates the incoming voltage to the 
nearest quantized value, assuming a 1V/octave control voltage.  The 
standard Blacet PROM has 16 quantized scales, and the Quantizer PROM 
offers 256.  http://stretta.com/~matthew/resources/waveproms/index.html  
(Too bad these are not currently available.)
