The scale quantizer, microtuning in Audulus 3
  • Firstly, am a new user and am enjoying this app, the possibilities...

    I'd like to try and understand what's going on in the quantizer. There was a discussion in a previous thread but the example was given inside an old patch which can't be opened.

    The patch takes in notes, assigns division of the scale and with a bit of tinkering with a switch it's entered in to the function:
    p-floor(p)-.5+(1-on)
    and then through a system of note selection, then through a function:
    p - offset.

    What's going on with these equations p-floor(p) and p - offset. I don't see frequency equations here that I've been reading up on, where would I be able to put in ratios and how can I increase or decrease the number of notes in the scale? Any help appreciated...

  • Thanks Robert, superb! Will have a session on this. Am picking up on the signal 0 standard 1vDC too and it being in the linear domain for manipulation. Thanks for the insight and sharing the knowledge. I'll go, experiment and will be back with a postworthy creation, hopefully, sometime soon.
  • Been tinkering, came up with a 53 even tempered one for now. Am looking at getting ratios in there, with a bit of help from scala, am still reading up on it all.

    I'm not sure if the the "abs tree" in the quantizer is ok but it seems to work.
    At the end of the abs tree is a pitch correction, as reference hz is usually tuned to A, in this case a microtuned A which puts the C slighty out. I wanted to experiment with this in C where I'm used to visualizing modes etc.
    A key shift might be useful for keeping in tune with other normally tuned instruments for key changes with this method but I'm too much of a noob for that at the mo.
    Just observing that the quantizer sometimes goes ballistic when fed a "0 - 1" lfo, it shoots up an octave.

    Anyway, check it out, cheers.
