Re: [gentoo-user] Zynaddsubfx connected to Rosegarden WITHOUT Jack?

[meino.cramer@gmx.de]

Hi Michael,

 I will try (again) to be a friend of Jack (NOT "Daniels" ;) )...

 What I dont understand: Why all this hassle with Jack if Rosegarden
 has the ability to connect directly to Zynaddsubfx without any
 other gadget (see Studio->Manage Midi Devices, start Zynaddsubfx
 first)??? And if instructed so, why does this dialog still pops
 up and reminds me of a non existing Jack connection?

 I tried the masked version 11.06 of rosegarden: The same effect.

 I removed the "jack" USE-Flag from make.conf temporarily and
 rebuild rosegarden: No change.

 Ok, I will try jack...again...sigh.

 Best regards,
 mcc
