[CM] How to fix: Can't schedule events in non-real time while RTS is running.?

[Emre Sevinc]

Hi all,

I keep on studying Notes from the Metalevel and I've just
finished the chapter about Steve Reich's piano phasing composition.

I was able to run the code successfuly, however after
I have listened to it I wanted to play a very simple note
and to my amazement I can't do it:

(define one (new midi
              :time 0
              :keynum 60
              :duration 2))

(events one "myscore.mid")

It says: Can't schedule events in non-real time while RTS is running.

And then I tried the example that worked just a few sec. ago:

CM> (events (piano2 phasing-trope 1 1 .5 4) "reich.mid")
Can't schedule events in non-real time while RTS is running.
NIL

CM> (events (pphase phasing-trope 1 1 .5) "reich.mid")
Can't schedule events in non-real time while RTS is running.
NIL

I searched for RTS in the Common Music dictionary and I saw
that there's a function rts-stop however running that
function and trying to play something I received the very
same error. I also checked rts?

CM> (rts?)
NIL

How can I make Common Music start playing MIDI again?
Is there a way to do that without exiting Emacs and restarting
Common Music?

BTW, my system details:

$ uname -a
Linux debian 2.6.11-1-686 #1 Mon Jun 20 22:00:38 MDT 2005 i686 GNU/Linux
$ sbcl --version
SBCL 0.9.2


Happy hacking,
Emre S.
