This directory contains an example of how you can include
|
||
|
|
recorded MIDI tracks into a MMA song. This is very quick,
|
||
|
|
dirty and not-all-that-great-sounding, but it serves as a
|
||
|
|
demo.
|
||
|
|
|
||
|
|
First off, I recorded two takes of the solo line for
|
||
|
|
Frankie and Johnny. I did this by recording me playing
|
||
|
|
my synth via the the Linux program arecordmidi, but
|
||
|
|
just about any MIDI recording should work.
|
||
|
|
|
||
|
|
For the first track recording I used the command line:
|
||
|
|
|
||
|
|
arecordmidi -p64 -b120 -m64 -t192 -s rec1.mid
|
||
|
|
|
||
|
|
The command line switches:
|
||
|
|
|
||
|
|
-p64 ALSA midi input port 0:64
|
||
|
|
-m64 Play a metronome on ALSA port 0:64
|
||
|
|
-s Split recorded tracks
|
||
|
|
-t192 Set beat division to 192 (the same as what MMA uses)
|
||
|
|
-b120 Tempo of 120 bpm
|
||
|
|
|
||
|
|
If you play this back you'll hear a piano playing the melody
|
||
|
|
at 120 bpm.
|
||
|
|
|
||
|
|
The second track recording also has a piano voice on playback, but
|
||
|
|
used a different set of switches:
|
||
|
|
|
||
|
|
arecordmidi -p64 -b100 -m64 -t192 -s rec2.mid
|
||
|
|
|
||
|
|
The important one here is the tempo which is 100. If you play this
|
||
|
|
file back you'll get some quite awful sounding piano with vibrato
|
||
|
|
and wheel effects. Really, the only reason I recorded this is to
|
||
|
|
see what happens with the wheel and vibrato button. BTW, I have
|
||
|
|
not done this kind of playing in the past and it is hard to get
|
||
|
|
good sounding wheel/vibrato effect :)
|
||
|
|
|
||
|
|
A third track recorded is a one bar drum solo. Hey, it's not a wonderful
|
||
|
|
drum solo, but I'm not a drummer ... and this is just a demo :)
|
||
|
|
The drum was recorded just like the other examples above, but this time
|
||
|
|
we set our keyboard up with drum tones so we could hear it properly. Note
|
||
|
|
that when we include the file we transfer the recorded channel 1 to the drum
|
||
|
|
track (and if you just play it, it'll sound like a badly played piano
|
||
|
|
instead of badly played drums). Also note that we do a transpose=0;
|
||
|
|
this ensures that no notes are moved, even if there is a global transpose.
|
||
|
|
Including drum solos were a major reason to write this code in the first
|
||
|
|
place, so please make use of the feature ... and do share some good solos
|
||
|
|
with the rest of us!
|
||
|
|
|
||
|
|
Now, we have some tracks. It is so easy to combine these with a
|
||
|
|
MMA song! Just look at the file frankie.mma which is quite fully
|
||
|
|
commented. Note the tricks, they're used for a reason :)
