How do you mix time signatures?

Post by maranite »

I'm reading Rick SnowdenSnowden's excellent "Making dance music" book... in it he describes a rhythmic technique of mixing a 4/4 signature "4 to the floor" 16-beat rythm with a 3/4 signature percussive triplet.

When I tried this on Krome, changing the time signature affected all tracks. Is there a way to mix time signatures? If not, how do I create the above without resorting to manually editing notes in the piano roll?

Hi, you can't have mixed time signatures in a bar in any sequencer (to my knowledge).

So you'll need to program it manually, which is not that hard. Especially if you get the feel for the patterns.

I have to a similar thing in Welsh Floyd. There is a part in "Hey You" from "The Wall", where is a single piano note (the intro sound from Echoes) that sounds like a sonar ping and which appears to be receding. The track is 4/4, and the ping is played in 5/4 over seven 4/4 bars

I'm not 100% sure of your example, but either it is a mixed signature pattern like the one described above where they will coincide every set number of bars.

Or, it's two signatures at different tempos such that the bar lengths timewise match.

For example for 4/4 at 120 BPM, a 3/4 bar to match in time would need to be three quarters (3/4 ! :) ) of the 4/4 tempo, so would need to be played at 90 BPM

With option 1, it's fairly easy as you playing with notes at the same tempo, the second example is the harder one, where you need to get editing note positions

Pages like the following can be quite handy for working out calculations

Thanks for the reply Derek.

What I was hoping to achieve was two tracks with different signatures, where a bar took equal time to play on both tracks. But it looks as though Korg are storing midi notes based on "time since start of current bar", as opposed to "time ellapsed since start of song", so when you switch from 4/4 to 3/4, you loose all the notes in the 4th beat.

In the past I have accomplished this by setting the meter to 1/1 (one quarter note per measure).
