This is Steinway_IMIS soundfont, version 2.2.
This version fixes the issue with loops. I hope this is the good one
and there are no more remaining major bugs.
Marcos is a little busy right now, so he asked me to make this fix. He
is thinking to make other improvements, so expect more updates soon.
Is anybody out here in LAU land have experience with PISound?
I have just bought one and am having quite sever teething problems with it.
It keeps freezing for ~45 seconds when running X and I cannot get it to
use the full display.
If not me then who? If not now then when? If not here then where?
So, here I stand, I can do no other

I recently bought a LinnStrument from Roger Linn Design:
It is a great isomorphic midi-controller, and as such it is immediately
recognized on Linux.
The distinguishing feature of the LinnStrument is that it senses 3
degrees of freedom on each note: x-direction, y direction and
z-direction (pressure). The x-direction is mapped to pitch-bend, and
y-direction to CC74.
A cool feature is the "slide", where the pitch-bend is used to slide
between all notes in a row.
To allow individual pitch and CC74 values for each note, it sends each
note on a separate midi-channel ("MPE"):
Bitwig has added support for this, and there is 20 presets in version
1.3.11, where this is used (tag: linnstrument). The LinnStrument
controller is not recognized automatically on Linux in version 1.3.11,
but it can be configured manually, and then it works fine. Note that
both midi-in and midi-out has to be configured, if not there is no
sound! It should look like this: https://ibin.co/2msBJVgpKtf9.png
Now I would like to also use it with the free Linux synths.
Here's what I have been able to make work this far.
PME works reasonably well: I can play polyphonic in MPE mode, but it
tends to miss the "note off"s.
I can get the slide to work, by setting
<param index="36" name="DEF1_PITCHBEND">2</param>
<param index="78" name="DEF2_PITCHBEND">2</param>
is a preset.
I can not get MPE to work.
Sending only on one channel, and setting PWheelB.Rng to 2400 cents, I
cant get the sliding to work, but only when playing with one finger.
If I enable MPE on the LinnStrument there is only an occasional sound,
when it happens to send on the channel, that Zyn is listening on.
I'll love to hear if other LinnStrument users have been able to do more
with any of the free synths on Linux.
All the best,
Mamba release v1.9 is out
Mamba is a Virtual MIDI keyboard with some extended, unique features.
This is a quick fix release as I've forgotten to implement jack MIDI
input forwarding to ALSA MIDI output.
Also it implement proper French translation thanks to Olivier Humbert.
Mamba is released under the BSD Zero Clause License license
The GUI is build on libxputty - A damn tiny abstraction Layer to create
X11 window/widgets with cairo surfaces
To build Mamba from source, the following dependencies must be meat.
So, here is the project page:
and here you'll find the last release:
I am currently trying to get the members of my accordion orchestra to
commit to rehearsals using Jamulus. Under Linux, Jamulus uses jackd to
access sound. There is a "JamulusOS" bootable image that will use Linux
to access the soundcard.
Now I want to recommend something to band members (and/or get it myself)
when their sound quality and/or latency is not up to par. My own
collection of sound cards here tends to be Firewire, and supporting that
is not really feasible (the finances would be strained by requiring a
Thunderbolt->Firewire adapter and Thunderbolt is not a given, while
Firewire is not something modern people can think about, and my
Expresscard Firewire adapters still require an actual Expresscard slot).
My own solution right now is an Alesis iO/14 which runs with a roundtrip
latency of about 160 samples at 48kHz. I've just dug out my
still-not-resold RME HDSP Multiface with a PCMCIA Adapter in an
Expresscard-to-PCMCIA adapter which is sort of a reference interface and
it delivers 62 samples roundtrip delay. Which is impressive but nobody
has the interfaces for that anymore and it would not be a recommendation
because of its pricing.
I've lent out one Tascam US-122L interface and Tascam has 64bit drivers
for it on its web page that work reasonably well. Wow. Under Linux, I
have not been able to get it to work recently and it uses really obscure
and undocumented Alsa modes to get at the data: to provide full-duplex
at higher sample rates (48kHz? 96kHz? 24bit? Don't remember) via
USB1.1, it has its own protocols that are not class compliant.
So while it miraculously does work with modern Windows, it would not be
a useful option for JamulusOS. And I am sure I'd get a JamulusOS setup
to run on other people's hardware, and don't have what it takes to make
Windows dropout-free, what with all its secret background processes. So
that interface is only good for people who feel competent at hardware
jiggling with Windows.
So I am lacking a reasonably solid recommendation of (possibly older but
reasonably quality) hardware with 1 or 2 mic inputs and +48V phantom
power and likely USB2.0 HiSpeed class compliant, possibly 2 headphone
outputs (the lockdown permits two households convening), good
reliability/support under Linux (meaning no obscure software and/or
Windows required for dealing with hardware mixers and mic preamp
boosts), reasonably low roundtrip latency at 48kHz (does not need to be
the insane 5ms from the RME DSP Multiface).
Something that I would not mind taking back. And which is dirt cheap
I know, I know, wishful thinking. But I will not persuade people to buy
old laptops for this feat, and while I might try starting them off their
built-in soundcards/mics to get them warm to the idea, I need a good

On behalf of the LAC 2020 organization team we'd like to welcome you all to
LAC 2020 which due to the current confining situation in France will take
place via teleconferencing on Nov 25-27.
A Big Blue Button (BBB) instance, the teleconferencing software that we use,
has been set up for conducting the conference. We will follow up by
publishing the official link both by mail and on the conference website
<https://lac2020.sciencesconf.org/> when the conference starts.
Additionally, in case you cannot attend, note that all talks will be
The programme is beinng finalized and is available here:
If you plan to attend, please take the time and register here:
As usual, the conference can be attended free of charge.
We apologies for the delays in announcements
See you at LAC 2020!
This is something I put together a short while ago, that was a proof of the
synth patch and the MIDI-learned technique I briefly performed on LAC.
It was the first time I'd actually used this technique and was recorded in a
single pass. The only editing was removal of some ghost notes where I'd clipped
the adjacent key along with the one I intended.
The patch is 'Multi Rushes', in my 'Companion' bank (added about 18 months ago)
and the learned items are Filter Q and Filter Cutoff in the MIDI Controls
I hope you like it.

Thank you for your reply. I solved this problem shortly after making
my original post (isn't that always the way!) - so I logged into the
list and deleted the post. But looking at the archives it still seems
to be there.
The problem turned out to be simply that, as the dialogue first
appeared, the selected directory was shown as /home/david
As soon as I normalized this to /home/david/ all was well.
Of course, once things are up and running properly I'll use a dedicated
directory, but as I was only just trying to set things up, and to get
Jack, Qtractor, the sound system and my electric piano talking to each
other nicely, I wasn't bothered about having a temporary file in my
Thanks again for your help.
