Hello all, There's no ALSA sequencer available in jack on Fedora 11 x86_64, using CCRMA's jack audio kit: qjackctl reports: "Could not open ALSA sequencer as a client" "ALSA MIDI patchbay will be not available" And further: "ALSA lib seq_hw.c:457 (snd_seq_hw_open) open /dev/snd/seq failed: No such file" This is an Acer Aspire 6939 laptop to which a M-Audio Axiom 25 is connected via USB. Does this have to do with the laptop's hardware ? Thanks.

There _is_ a debug compile option, but I can't see that helping you or me. What I might find useful is a short recorded example of the clicking (off list!), and some basic details of your system - cpu, memory, linux distro. cheers, Cal

Anyway, what editor do you use? The percussion matrix editor I guess? I like more the matrix editor even for drums.

I love hydrogen to edit drums. You can use 'klick -T -f /path/to/tempomap' (klick as master jack and reading a tempo map in text mode, check klick) and choose Jack Transport in hydrogen if you don't want a fixed tempo. i tried openoctave midi but found it to be even more > buggy then rosegarden (doesn't even render correctly) > > thanks for your help > Dieter > > > Cheers!

What results do you get with other versions of Zyn.? What distro are you using? Any odd-ball hardware in your system? -- Will J Godfrey http://www.musically.me.uk

rosegarden midi editor woes

by Dieter Plaetinck

Hi guys, I'm using rosegarden 1.7.3 (=latest release) I think this is the best tool to do midi editing for drums on Linux (please tell me if I'm wrong), but it does do some weird things which get on my nerves: - inability to properly select (groups of) notes: frequently it selects notes I didn't click, or it selects a group when I just want one note, etc - inability to properly insert notes: when i insert 1 1/32 note, and then want to do one next to it, it removes the one i just insert (even with quantize set to 1/32) - copy paste behavior: when pasting, it pastes the notes at the beginning of the song (is this pebcak?) - when zooming in/out, the song jumps back to the beginning, even if the 'time pointer' is somewhere else. i could mention some more things, it only takes me a couple of minutes to start hitting time-wasting oddities. anyone had similar issues? can it be solved? is there something better then rosegarden? i tried openoctave midi but found it to be even more buggy then rosegarden (doesn't even render correctly) thanks for your help Dieter

by Jonathan E. Brickman
