Revision 1.11, Fri Dec 2 10:34:50 2011 UTC (12 years, 6 months ago) by ratchov
Branch: MAIN
CVS Tags: OPENBSD_5_1_BASE, OPENBSD_5_1
Changes since 1.10: +8 -8 lines 

reuse midi-control code to implement midi thru boxes and remove
the old midithru implementation; less code, less bugs. As a side
effect, midi output doesn't implement running status "compression"
any more.
