For a sequencer it anyway still is a bug.

Fortunately this even isn't true for Qtractor. It's possible to change
the program within one MIDI track. Some sounds need to be used this
way, e.g. the European DX7 factory Cartridge sounds "ST.HELENS" and
"EXPLOSION", since the sound "ST.HELENS" is needed to trigger
the sound "EXPLOSION" by a program change.

It's absolutely against MIDI standards and against human sense to
enforce a program chance at the start position, when a program change
is found at a later position.

For example, you're using a sequencer for improvisation. By hand, not
by a sequencer you are playing a synth, after a while you start the
sequencer that in addition to you plays the same synth and after a while
later, the sequencer should change the program number.

It's common practise to do something like this, it's not freakish and
the MIDI standard implies this option.

No matter how you look at it, it's a bug.

The sequencer should record and play what the musician plays.
