Hi all, I am desperately trying to get the Jazz++ sequencer to run on Linux 7.2 with a softsynth and ALSA 0.9.0. I manage to use iiwusynth with pmidi or vkey in the following way : $ iiwusynth -m alsa_seq sf/sYnerGi-8Mb.sf2 $ vkeybd --addr 128:0 But when I launch jazz, I get the following error messages : ioctl: Inappropriate ioctl for device ioctl: Inappropriate ioctl for device subscribe: Inappropriate ioctl for device ioctl: Inappropriate ioctl for device unsubscribe: Inappropriate ioctl for device I never got any sound out of the pianoroll, I never got any sound when loading a midi file and pressing play. I checked how the interface works by downloading the win32 version. I tried both the rpm and the binary versions (ver 4.1.3) as I couldn't manage to compile version 4.1.8. I am using the default jazz.cfg file which is set for ALSA. What am I doing wrong ? Is Jazz++ not meant to use alsa_sequencer ? -- Operant conditionning : A process in which responses are learned on the basis of their rewarding or punishing consequences.
