[CM] Can't save new files

[Philippe de Rochambeau]

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

To do this set your your Midi Out port in Grace to your Mac's "IAC Application Bus" , then inside  Logic or Garage Band set its input port to "IAC Application Bus". You can send your midi data to sibelius or Finale (or any other app you want) using the same mechanism.

I must need to set the working directory differently when the app starts up, but I haven had any time at all in the last 2 months to look into it, ill have some time in mid june when I can try to figure it out.
