dear list members,

=<problem>=========================================================

i want to user the Q as masterkeyboard and muse as sequencer to record the 
notes, but how? i can't get the Q working with the alsa midi through!

how can i change my setup that working with the Waldorf Q as masterkeyboard
and the PC (midi through==1) as Master, so i can play the Q and record it! 

first my setup:
| Waldorf Q | -out----in-> PC -out----in-> | Waldorf Q|
with either muse (midi trough set!) or this command: (dd if=/dev/snd/midiC0D0 
bs=1 of=/dev/snd/midiC0D0)
also note that "local off" is set on the Q so it can't trigger itselfe
locally, only over the midi wire trough the pc!

when i play the Q, strange things happen:
- -not every note is triggered (many don't get through)
- -faster playing (5-10 fingers on keys on Q) get diffrent midi error like
sending cc or program changes like pitch up, change of midi port numbers,
suddenly other sounds appear.
- -also strange sounds like sqeezing or very high never ending tones appear.

i know that this is not a BUG of the Waldorf Q because it is working with the
MC 50 (hardware sequencer from roland) well!

=<other stuff>=========================================================
if i set up the emu10k1 midiIN/OUT <-> muse (midi seq),
i can send midi-out perfectly form my pc <-> waldorf Q / MC 307 when i'm
playing with the virtual muse midi-keyboard!

what i can do (what's working):
- -can send sysex(dump) from waldorf Q successfully to PC (no faults)
- -can receive every sysex i sent from my PC <-> Q
- -can sent notes from muse to either the Q or MC 307 with success (virtual
keyboard of muse)!

special: with midi trough=1
- -using this command:
(dd if=/dev/snd/midiC0D0 bs=1 of=/dev/snd/midiC0D0)
it is working with the following setup:
| MC 307 | out----in> PC out----in> | MC 307 |
and it's even working with hi midi bandwith usage of the MC 307!

=<setup of alsa>=========================================================

version of alsa i'm useing:
- -1pre1 the latest source!
kernel:
- -2.4.22
soundcard:
- -emu10k1 with 2-3m large midicable
