I see that engrssc claims to have run Miditzer and Hauptwerk simultaneously on
a Mac Pro.
I know that Hauptwerk would have no trouble but I have found that running even one
copy of Miditzer on my iMac does not work. Miditzer is a Windows program and there
IS NO Mac version.
I have tried to run Miditzer under Wine on my iMac and while it loads and "sort of" works
the "M" menu cannot be accessed which makes it rather useless.
There is also a problem with the Wine "midi in" port when trying to play an organ which is
running under Wine --- it suffers from buffer overflow and loses midi events. This means
that the stops do not work properly especially when changing several in quick succession.
This port does work correctly when connecting to the organ via a real midi cable - it is
the virtual connection which does not work properly.
I have produced two Windows organ programs which DO run properly on an iMac under Wine
these are:
1) eplayWin32 which plays Estey and Wurlitzer e-rolls on multiple different organs
2) multiOrgan which simulates multiple different organs and actually produces the
organ sound.
These programs connect to each other via a standard midi port and either a real or
virtual midi cable.
If you use eplayWin32 to play a Miditzer both running on iMac under wine you will experience
all of the problems I have listed above.
