I am having trouble using a midi keyboard to spawn
audible events.  I have done this some time in the
past, but have recently attempted it again with
3.47 without success.  

I am getting instrument triggers from the Midi 
keyboard, but no sound with -odac or otherwise.

Here are the specifics:

Linux csound3.47 (no luck with generic source,
or Linux Specific binary from Dave Phillips).
Pentium 150, Soundblaster Midi, yada yada yada..

***orc***

	sr	=	44100
	kr	=	441
	ksmps	=	100
	nchnls	=	1

	instr 1

		ivol	ampmidi	10000
		ipitch	cpsmidi

		asig	oscil	ivol, ipitch, 1
			print	ivol, ipitch

			out 	asig 
	endin

***sco***

	f1 0 16384 10 1 
	f99 100 1024 10 1


***command line ***
	csound  -M/dev/midi0 -o dac  orc sco

I believe that the instrument is getting the proper
signals, because the debugging 'print' statement that
I put into the orc yields output like:

	MIT Csound: 3.44 (Jan  9 1997)
	orch now loaded
	displays suppressed
	midi channel 1 using instr 1
	audio buffered in 512 sample-frame blocks
	hardware buffers set to 1024 bytes
	writing 1024-byte blks of shorts to dac (WAV)
	SECTION 1:
	ftable 1:
	new alloc for instr 1:
	instr 1:  ivol = 2656.250  ipitch = 1046.502
	instr 1:  ivol = 2656.250  ipitch = 1174.626
	instr 1:  ivol = 2343.750  ipitch = 1318.436
	instr 1:  ivol = 3906.250  ipitch = 1396.874
	instr 1:  ivol = 1953.125  ipitch = 1318.436
	new alloc for instr 1:
	instr 1:  ivol = 2109.375  ipitch = 1174.626
	instr 1:  ivol = 2031.250  ipitch = 1046.502
	instr 1:  ivol = 2187.500  ipitch = 987.739   

The pitch is right. The volume is right.  The instrument
is clearly being triggered.  Why no output?

Thanks,

Toby
