Does anyone know of software that can generate MIDI messages from a touchpad?
The idea would be to send CCs to a sequencer or soft synth, but being able to
send it to an external hardware device would also be very useful.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
Hi,
I'm struggling with my jack setup again. I am running Devuan Chimaera
and the MB has a builtin sound chip (ALC887)
which works using just ALSA. I had an Audigy sound card, and Jack worked
OK with that. Longer term, I'll by using
a UDAC8 USB sound module, but it's not here at present, and I expected
to be able to simply switch the Jack output
device from the Audigy to the ALC877. I can play a test file through
ALSA (aplay test1.wav) which is OK, though
a bit low volume, but when I reconfigure jack to use it, I don;t get any
system output on QJackCtl, and jack-play
gives no sound, not surprising if there's no port to connect to.
Last resort is to put the Audigy card back in for now.

Hello all,
Since four days now, the melody I try to reproduce below is
haunting my brain. Don't know how i picked it up.
It's a popular classical piece which I have heard many times,
from the romantic period and as I remember it, for string
orchestra.
But I can't find out what it is. Tried some of the 'find a
melody' sites, no succes.
6/8 (or maybe 3/4)
- = continuation of previous note by 1/8
| A-- G#-- | A---- B | C-- B-- | Bb----- |
| Bb-- A-- | G----- | F-- G Bb A | Bb----- |
Can anyone identify this ??
Many thanks !

This sounds a bit like humdrum, a short of MusicXML alternative used by
musicologists to do statistical analysis of compositions.

Having sorted out my previous problem with Jack, I've got round to
trying to sort out the multi-channel outputs
via a MiniDSP UDAC-8. This is an 8-channel USB output device. I plugged
it in and it shows up with 'aplay -':

Going into QjackCtl and changing the output device to hw:UDAC8 and it
seems to work - jack restarts and the Graph
window now shows system with 8 playback channels. I then tried using
jack-play to play a short test .wav file
which works fine on the ALC877 but fails with the UDAC-8:
------------------------------------------
Cannot read socket fd = 8 err = Success
Cannot open jack-play-3712 client
CheckRes error
JackSocketClientChannel read fail
JackShmReadWritePtr1::~JackShmReadWritePtr1 - Init not done for -1,
skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1,
skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1,
skipping unlock
jack_client_open() failed: jack-play-3712
-------------------------------------------
I then tried using just alsa
aplay -D plughw:UDAC8
which works, while
aplay -D hw:UDAC8
fails with:
------------------------------
Playing WAVE 'test1.wav' : Signed 16 bit Little Endian, Rate 48000 Hz,
Stereo
aplay: set_params:1349: Channels count non available
------------------------------
qjackctl only allows devices with hw:* and not plughw:* so that could be
something, though I don't
understand the internals of jack and alsa.
Anyone able to set me right and get this to work will win my undying
gratitude!

Doesn't ring a bell here, figuratively speaking. But maybe you can
find it via http://www.themefinder.org/ ?
I couldn't find it with themefinder though, but I'm not sure if I used
it correctly.
Thank you both for your suggestions. Having experimented further, I
find that, as I expected, the earpieces are completely inaudible when
they are not in my ear (they are just the little ear-bud type of
thing).
The default connections shown bu aJackCtl are:
System(capture) to qTractor and PulseAudio JACK Source
qTractor and PulseAudio JACK Sink to System(playback)
This seems about right, to me, I experimented with removing the
connections to/from PulseAudio, but this doesn't make any difference to
the problem I have been getting. I also experimented with muting
various things in Pavu, without any success.
So either I am doing something very basic completely wrongly (quite
likely!), or perhaps there is some sort of crossover going on in my
sound card between input and output.
I did attempt to repeat my experimental recording on my desktop
computer, but couldn't figure out how to get the input from my webcam's
microphone into qTractor. When I start Jack, the System(capture) node
doesn't appear in the connections graph at all.

Several years ago I managed to produce some multi-track midi files
using qTractor.
Now I want to do something fairly simple using audio tracks. Just to
get myself back into using qTractor after a very long break, and to
find out how to do what I want, I decided to try something very simple
to start with. I want to record a guide track using my voice, and then
record 3 other voice tracks (separately), listening to the guide track
through an earpiece. Then I shall delete the guide track and
experiment with altering the pan settings on two of the other 3 tracks
to see if I can get a good stereo effect. I'm using an HP laptop and
its internal microphone, with an earpiece plugged into the computer's
headphone socket; no sound comes from the computer's speakers, of
course.
Recording the guide track is no problem. To record the second track, I
set it up as an unmonitored audio track and set the guide track to
solo. I then record the new track whilst listening to the guide track
through the earpiece.
But after recording the second track, even if I delete the guide track,
I can still faintly hear what was on the guide track - in other words,
the new track has recorded the contents of the guide track at the same
time as the new input from the microphone. I have tried this several
times, and I can't figure out what I'm doing wrong - probably because
I'm a musician and not a sound engineer.
If anyone has the patience to try to steer me though this, I shall be
extremely grateful.
David
