OpenMPT 1.23.02.00 was supposed to correct a bug that caused everything to be played too fast on a fresh installation when the user never touched the sound configuration. Under some circumstances, upgrading to yesterday's version could create the opposite effect, i.e. sound was playing too slow. This bugfix release will fix both the new and old bug.
Additionally, a small change has been made to instrument plugin handling: If an instrument specifies a MIDI program / bank to be used, OpenMPT now always re-sends this information after restarting playback. Previously, this information was only resent during first play or when it was changed by the user. This fixes some external softsynths controlled through the MIDI I/O plugin.
