Hi Heinrich,
Here’s how I have been doing it so far.
What I am trying it to is is to play a bf4 for a beat and a half (assuming
there are 60 beats/minute), a c5 for 1/2 a beat, while playing « metro[nome] »
beats every second.
The problem with this approach is that it is hard to keep track of aggregated
time (time 0 + 1.5 second + 0.5 second rest = 2 seconds, which means that the
second piano note should start at time 2, etc.)
I will trying rewriting my code using a loop and lists, using a variable to
compute aggregated time.
Philippe
-----------------
mp:instruments(1, 77)
begin
; time, dur, key, amp, chan
; g4 -> bf4
mp:midi(key: keynum("bf4"), chan: 0, dur: 1.5, time: 0)
; metro
mp:midi(key: keynum("c0"), chan: 1, dur: 1, time: 0)
; a4 -> c5
mp:midi(key: keynum("c5"), chan: 0, dur: .5, time: 2)
; metro
mp:midi(key: keynum("c0"), chan: 1, dur: 1, time: 1)
end
