Hi Daniel, Sorry for the late reply on this subject. To do exactly as you describe it is possible to take the cosine or sine of a line over period. Use [vline~] as it is much more flexible. Take a line running from 0 to 1 in some time, and use the cosine function to obtain exactly one

Daniel, You could make a table with a sine wave form in it and drive it with a [tabosc4~] object. The only way (as far as I know) to ensure sample accuracy for this is to set the blocksize to 1 (use the [blocksize] object). Otherwise you might run over the end of your table by as much as 63

Hi, You can reset the phase of an [osc~] by sending a message to its right inlet. In your case the message would be [0.25( , i.e. 1/4 of the way through the cosine wave form, which is zero. That won't work at the note off, though, so the sensible thing would be to use an envelope. But, if

I'm working on re-realizing a piece I wrote for subwoofer that is meant to be felt by touching the speaker cone instead of hearing it. This is done by using sine waves from around 15 to 26 Hz at low volume adn utilizing difference frequencies to get lower frequency pulses. My problem is that the
