There's many ways to do this in most professional level sequencers. One way is beat mapping, while another is expansion and/or compression.
If QWS doesn't have a tap tempo feature it'd be a good add on. That way you could tap out the tempo you want and then quantize to deal with any fluff. It would also allow tempo rigidity to tempo changes. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Raymond Grote Sent: Friday, December 30, 2011 12:11 PM To: QWS list Subject: Re: QWS List Changing midi tempo separately, But, let's say, someone messed with it and now the actual contents is at 140 BPM, however the tempo in the midi file says 120. I haven't found an easy way to fix that. Time stretching programs for audio can do it. You enter initial and final BPM and it calculates the ratio, very precisely and does it. But I haven't seen anything for midi yet. Unlesss Voyetra has a feature that can handle that. i know nothing about that sequencer, so it might. It would be more difficult for QWS anyway since there would be a lot of rounding going on to expand the midi data, but the time expand tool definitely is a start and could help if used carefully. ----- Original Message ----- From: "Nicole Massey" <[email protected]> To: "QWS list" <[email protected]> Sent: Friday, December 30, 2011 12:45 PM Subject: RE: QWS List Changing midi tempo separately, > Actually, every MIDI sequencer I've used at a professional level had a > feature to take a MIDI track and get it into a proper tempo.
