Minim sequencing play and record functions

Hi Folks!

I've been working on a script where in very simple terms I would like a random beep to sound (Audioplayer beep - working!) and after that beep, a sequence of audio tracks to play (currently arranged in the array audio) and eventually audio recordings to be made (not set up yet).

My current issue is that

audio[0].play(); 

is working perfectly but not then playing the second audio track. I've tried setting this up as a separate event (

void playrecord()

) and have found this thread very helpful to get the crux of the code from @GoToLoop: https://forum.processing.org/two/discussion/12966/how-to-play-an-audio-file-sequentially.

Ideally I would like to sequence it as audio 0 play, record audio input 0 through microphone, audio 1 play, record audio input 1 through microphone. All before the next "beep" sound is made.

Can anyone suggest what is going wrong?
