Buchla Music Easel CV out to Freq in Max/Msp


    Apr 24 2014 | 10:00 pm
    Hi,
    I'm trying to get cv information from my Music Easel and to
    quantize it in 1V per octave.
    Buchla CV range span from 0 to 10 v.
    I use a Motu Ultralight, so I'm capable to get CV (and send them to the Buchla using proper 1/4" jack to banana cables).
    Any suggestion about how to perform the conversion CV to Midipitch.
    Many thanks,
    Federico

      What mechanism are you using to get DC values into the computer? Most audio interfaces (even the Ultralight) will DC-block input values; the Silent Way CV Input requires a VCA dedicated to modulating the value in order to pass the signal pass the audio input blocking.

      Hi thanks for your reply.
      I simply use custom cables 1/4" to Banana, no specifc other hardware.
      I take the cv out from Buchla and I route it to my Motu.
      I'm able to use the other cv's but I have no idea about the conversion strategy
      I should apply to the signal.
      Many thanks,
      Federico
