I am unsure how to use the tempo controls of Csound, wonder if I'm a doing
something wrong, or if there could be a bug?

When I play the following score it doesn't sound how I would expect - it
sounds like the 6th is played on top of the 5th note.

If I 'play' the tempo change instrument some milliseconds earlier (the
uncommented line), it does sound how I would expect, the new tempo coming
into effect on beat 1.



-odac -t60



sr = 44100
kr = 4410
ksmps = 10
nchnls = 1

instr 1
tempo 120, 60
endin

instr 2
aSin oscils 0dbfs/4, 440, 0
out aSin
endin



i 2 00.00 00.1
i 2 00.25 00.1
i 2 00.50 00.1
i 2 00.75 00.1

i 1 1 1
;i 1 0.999 1

i 2 1.00 00.1
i 2 1.25 00.1
i 2 1.50 00.1
i 2 1.75 00.1

e 1000





Furthermore, in the following I would expect the '-t' option to have some
effect on how the duration parameter for 'timout' is interpreted, but it
seems to have no effect.



-odac -t180



sr = 44100
kr = 4410
ksmps = 10
nchnls = 1

alwayson "looper"

instr 1
aSin oscils 0dbfs/4, 440, 0
out aSin
endin

instr looper
loop:
             timout        0, 1.0, play
             reinit        loop
play:
             scoreline_i   "i 1 1.00 00.1 0"

endin



e 1000
