Timing is the responsibility of the playing/controlling device, which sends On/Off etc data out and expects that it will be impemented immed. The playing of a midi file never involves the sending of any timing info to external devices. The effect of this change should be immediately heard, as this change is often used for dramatic effect in the music. So the ticks in the midi file do not change, but what each tick is really worth does.Īs has been said, there are midi files that may change the tempo any number of times during playback.

Exactly how each piece of software handles this comparison will be up to that piece of software, different systems may do it differently, but the calculation will take into account the actual tempo at that point in time, PPQ, etc, and if need be change the 'value' of each tick to a quantity of microsecs. This comparison will require some sort of calculation, as we are comparing two quite different numbers, ticks and microsecs. It would to this by comparing the tick value in the midi file, with the actual real time as determined by the device clock. The playing software would always know what the next event is, and it would wait until the next event is due, and then implement it. The midi file contains the tick count for each event, and this is fixed, and does not change, and is not subject to 'recalculation' - it is merely the relative spacing of the events. The PPQ and initial tempo settings are quite incidental, they merely set a base, and would usually be appropriate to the piece of music. Some of the comments here seem to be over-thinking things, making things seem more complicated than they are. Or are the BPM changes at time X calculated at time X, are there a message sent out at time X that says to peripherals that BPM changed? I can see now my question is a little confusing, but i mean the 'note, program and CC events' are they calculated 'using ticks ppq and bpm' before playup start. I find it confusing to say the least, right now i just handle BPM as a pre calculation together with PPQ 'before playup', but it seem a bit suspicious and probably wrong. I guess when there is many changes in 'BPM' in a midifile it is just used to calculate the events distance and when you change the BPM of track you recalculate it.īut then it do get confusing i have a midifile with changing in BPM all over the place 'a piano piece', if you change the 'playup' BPM all those BPM changes becomes fractions of their original values?Īnd if BPM is not a realtime change, how could sequensers interact 'sync' when BPM changes? However, being able to beatmatch by ear will help you deal with tempo variations the software may not pick up on.I think the answer is no to the question but not sure Most DJ software has built-in features to make the beatmatching process easier.From there, you can decide on the perfect spot to make the transition from one song to the other.

Concentrate on your cue and listen for places where the beats of the 2 songs no longer line up because of changes in tempo.Line up the first beat of the bar you choose with the first beat of another bar in the A track.

For example, maybe your B track has a loud bass drum beat on the first beat of each bar.

Start by taking songs that you know well and that have the same (or similar) BPMs, and listen until you find a good cue to guide you as you sync the songs up. This is especially true when you’re working with live recordings and vinyl instead of digital tracks. Even if 2 songs have the same time signature and overall BPM, the beats may not match up exactly. Practice beatmatching with 2 songs at once.
