Re: [Om-synth] And still Om won't sing to me

[S. Massy]

Hi there, me again,

I'm sorry to repost this question, but I've been trying to get a sound
out of om for some time now and am getting quite frustrated, all the
more so because I feel the problem is most likely quite trivial (maybe
something stupid I'm doing) and am really excited to give Om a real try.

Here below is _exactly_ what I'm doing with as much information as I can
provide.

1) starting jackd
# jackd -R -d alsa -p 256
-- jackd (0.100.7) works: tested with ecasound and timidity
2) Start om
# om
-- Om (0.2.0) loads without displaying any error message.
[SlowEventQueue] Starting.
[PostProcessor] Starting.
[AlsaDriver] Successfully opened ALSA sequencer.
[OSC] Started OSC server at osc.udp://localhost:16180/
[Main] Successfully locked all memory.
3) Load the sine patch.
# om_patch_loader /usr/local/share/om/patches/sine.om
-- All seems okay.
[JackDriver] Activated Jack client.
[AlsaDriver] Started realtime MIDI thread (SCHED_FIFO, priority 20)
[OSC] Registered client osc.udp://localhost:14439/ (1 clients)
[NodeFactory] DSSI_PATH is empty.  Assuming
/usr/lib/dssi:/usr/local/lib/dssi:~/.dssi
[OSC] Unregistered client osc.udp://localhost:14439/ (0 clients)
4) Connect Om's output to the soundcard.
# jack_lsp
alsa_pcm:capture_1
alsa_pcm:capture_2
alsa_pcm:playback_1
alsa_pcm:playback_2
Om:sine/output
# jack_connect Om:sine/output alsa_pcm:playback_1
-- No complaints from jack...
5) Play a midi file.
# aconnect -o
client 64: 'EMU10K1 MPU-401 (UART)' [type=kernel]
    0 'EMU10K1 MPU-401 (UART)'
client 65: 'Emu10k1 WaveTable' [type=kernel]
    0 'Emu10k1 Port 0  '
    1 'Emu10k1 Port 1  '
    2 'Emu10k1 Port 2  '
    3 'Emu10k1 Port 3  '
client 128: 'Om' [type=user]
    0 '/sine           '
# aplaymidi -p 128:0 scale.mid
-- aplaymidi plays, but no sound is heard...
6) I test the ALSA sequencer interface.
# timidity -iA 
# aconnect -o
client 64: 'EMU10K1 MPU-401 (UART)' [type=kernel]
    0 'EMU10K1 MPU-401 (UART)'
client 65: 'Emu10k1 WaveTable' [type=kernel]
    0 'Emu10k1 Port 0  '
    1 'Emu10k1 Port 1  '
    2 'Emu10k1 Port 2  '
    3 'Emu10k1 Port 3  '
client 128: 'Om' [type=user]
    0 '/sine           '
client 129: 'TiMidity' [type=user]
    0 'TiMidity port 0 '
    1 'TiMidity port 1 '
    2 'TiMidity port 2 '
    3 'TiMidity port 3 '
# aplaymidi -p 129:0 scale.mid
-- Sounds just fine...

scale.mid is a midi file produced with midge, a text to midi language;
here's what the input file looks like:
@head {
        $timesig = 4/4 $tempo = 120;
        }

@body {
        @channel 1 {
                /l4/c3 d e f g a b c4
        }
}

Well, I think that's as much info as I have; I would be really, really
grateful if anyone could point out what I'm doing wrong here...

Thanks!
S.M.
