Darren Irvine explains how to tinker about with Play Sequences in Music-X and assemble them into a song.


Scaling Velocity

Note velocity can be altered in a similar way to quantisation. This time, though, if you only want to scale some of the notes, you must Mark, rather than Select them. When using Mark you don't draw a box, but actually highlight the whole vertical section of the edit window. Click just before the first desired note, and drag until just after the last. All the marked events will be highlighted in a nasty pink. Again, if you make a mistake click on UnMark and start again.

"Scale Velocities" is found on the Tools pull-down menu. You are offered the choice of scaling the entire sequence, or just the marked events -- you choose. Two slider gadgets select the percentage of scaling at the start and end of the sequence. To just alter the volume of the sequence, these should be the same, with percentages less than 100 decreasing the velocities, and obviously percentages greater than 100 increasing them. You can also create crescendo and diminuendo effects by making the End scaling greater or less than the Start scaling.

Setting Repeats

For the purpose of jamming along with your sequences while you think up some more, it's easiest to put in a repeat marker at the end of each sequence so that they all play over and over at the same time. You can then take out the Repeats when you come to arrange the final song.

To add a repeat, click on Move and drag the marker so that it is exactly on the end of the sequence. Then click on Add, and then Set Repeats from the pop-up menu. When you next click anywhere in the editing window a REP:1 marker will appear.

You can drag this marker whilst still holding down the mouse button. Now one of the slider gadgets in the bottom right hand corner of the screen will change to REP. Drag this until you have a decent number of repeats, say fifty.

Storing your edited Sequence

Now that you have quantised, velocity scaled, and generally tinkered about with your sequence, select EXIT from the first pull-down menu. Then select STORE from the requester that pops up. Now when you click on PLAY, your perfectly formed sequence will play back, repeating ad nauseam (or at least the number of times you specified in Set Repeats).

Repeat steps one to six, until you have recorded all the tracks you need for your song. You will notice that when you record subsequent tracks, the previous ones play along. This is particularly useful for composing melodies on the fly, but if you find it too much (or need to play a sequence in a different key for example), click on the timing part of the sequences display line (this will probably contain something like 0000), until it displays "Off". To turn it back on, simply click on the same place again.

Creating a song

Once you have all your sequences recorded and edited to your satisfaction, you can set about turning them into a song. Go through each sequence and remove the repeat markers using Remove.

Next, pick an empty Play Sequence, and EDIT it. This will be your master control sequence. Use Grid to select whole notes (the biggest ones), so that it is easy to line up your Play Sequences. When you get more proficient, you can start to be a bit more daring with timings.

Hit Add, then Play Sequence, and then OK. You are now ready to start piecing together your track. Click on the area of the edit window where you wish to add the sequence. The vertical position determines which of the Play Sequences is added, with the first being at the bottom, and working up. Music-X is not always entirely accurate in this, but can sometimes produce unexpected and interesting results.

If the placement of the sequence is incorrect, or if it is the wrong sequence, click on Move and then on the sequence. Then use the cursor keys to move the sequence around. Holding down SHIFT whilst you use the cursor keys changes the length of the sequence by the length of the note selected in Grid.

Add as many play sequences as you need to make up your song. You can use the shifted cursor keys to make each one as long as you like, but in practice best results are obtained by ensuring no play sequence is longer than eight bars. If you want a sequence to play for longer than this (and of course with techno, most of your sequences will last the entire length of the song), just add two or more sequences consecutively. Any longer than eight bars seems to cause Music-X a bit of a problem and timing glitches can occur.

When you exit out from this Play Sequence, give it a name (like "Rough Mix 1"). You can create as many of these "Control Sequences" as you like, but it's probably a good idea to only play one of them back at a time unless you have a stupendous amount of polyphony available.

Saving your work

Save your song regularly -- every half hour -- Music-X is very stable but it is very easy to spend hours creating lots of Play Sequences, and editing them into a great song, and then forget to save the whole thing. Select "Save Performance" from the second pull-down menu, and click on OK to save all the parameters.

CANCEL will remove the requester, STORE will make the changes and return to the main screen, DISCARD will forget all the changes and HOLD will put them somewhere temporarily.


Good control over the volume is very important. Try using the random button to add life to otherwise drab hi-hat sequences.


A finished song is a list of play sequences. Here the ever-important bongos are being added.


If you have Music-X 2.0 you can use the Velocity Flattener function to simplify things still further.


The Velocity Scaling requester can be used to even out the most dynamically played sequence.


You can use Velocity Scaling to produce fade-in style effects.
