Hi ! Have you come across moresampler to generate your oto files ? It does a very nice job, but the values it produces are rather irregular. I wanted to keep the preutterance's timing, but with more standard values all over. Having too many different values affects a VCV in a noticeable way, and I was not going to do it manually, it would take absolutely forever. This tool I programmed allows you to set values automatically in your oto files and takes care of the offset according to the current preutterance. Of course, the uses of this tool are not limited to users of moresampler, which is why it is a bit more flexible than that. You could change, for example, change the cutoff of every first mora or change your preutterance and overlap from 300 and 100 to 250 and 83 without having to move your offset. Oto Adjust v1.0 For more information, I included a Read Me file. Hope it helps !
