fading in frequency modulation

Aug 26 2012 | 1:33 pm


Im trying to be able to modulate the fundamental frequency of an oscillator using a cycle~ object and converting it to a number. I basically want to be able to fade the frequency in after a long note so the modulation comes in towards the end of the note rather than from the beginning. The problem im having are smooth transition from non modulating to a modulating is difficult. is it better to work with signal rather than numbers in this instance?

I don’t know if i’ve understood, but, why don’t you play with adsr?

here I’ve deleted the sig~ object, is useless.

what I want is

Note on>PAUSE>Modulation fade in>Note off


Note on/modulation on>Note off

I still am not sure in understanding, but, try to understand this, is a bit messy, I’m not great with msp:

I think you should try to modify these patches.

If you haven’t already done so, I suggest you read MSP Tutorial 10: Vibrato and FM and MSP Tutorial 11: Frequency Modulation. The first shows the basics of how to implement vibrato (i.e., frequency modulation) in MSP, and the second, while rather wonky on the topic of FM synthesis, shows a good way to control the depth of modulation over the course of a note.
