Hi,

i recently updated hatari from 1.8 as supplied with my linux distro to a self built 2.0 version.
Is the self built version using sources from the 2.0 release commit, or
Hatari's Mercurial tip?
If 2.0, could you test also latest Mercurial version?
as seen in the 1.9 changelog, there are improvements in the midi accuracy.
since i use hatari mostly for synth programming via atari editors, i often use large sysex dumps that get sent or are received by the editors.
after updating to 2.0 there are much more errors on the receiving synth, so it seems some data gets lost. 1.8 also has some errors, but much less.
Which machine you're emulating?
For ST/STE, the most significant change was in v2.0 (not v1.9),
switching from the old UAE CPU core to more accurate WinAUE CPU core.
Also, RTC being used only with the new MegaST/STE machines.
For TT & Falcon, which already used WinUAE CPU core, the emulation got
more accurate, but there were few caching related bugs causing
regressions, which are fixed only in Mercurial tip.
so, what was changed in 1.9? are there any buffersizes that are smaller now? (usually the problem with corrupted sysex dumps)
Details are in the v1.9 release notes:
