I stand by my recommendation for Roland/Edirol. The entry level model is labeled R-05, 


As well as user reviews it's also helpful to look at the specification, and 
even the manual.

.but best of all, there's a site here which has sound samples:-

http://www.wingfieldaudio.com/portable-recorder-sound-samples.html


For anyone interested, here's my reservations about the Roland gear.

The R-05 has an unspecified angle between the mics, and the recording methods
in the manual hint that this angle may even be 180 degrees.
(and indeed, the appearance of the unit tends to confirm this, as does
reference to the R-09HR)

A 90 degree angle is what we're looking for to get a decent stereo recording of 
a solo instrument.

Indeed the R-09 HR has a very wide polar pattern for the mics, the result being 
an unfocused
stereo image of the instrument and more room sound for a given mic placement.
( and as the instrument is way off axis for both the mic capsules, you don't 
get the best
frequency response).

Yes, those are my experiences with the Roland too. Several friends
have one (my music school had a scheme where you could buy one at a
discount). It's a convenient tool, but the mic placments limits the
use somewhat.

I have an H2, too.

Thank you for the tip about 24-bit recording.

It's probably worth pointing out that the volume control on the left is for 
playback through speakers/headphones.  The recording level can be set with the 
double arrow buttons either side of the red 'record' button, on a scale of 0 to 
127.

I'm still learning . . .

hi Stuart,

In order to be sure of avoiding distortion when just using just the L/M/H 
control 
for volume I often end up with a quiet recording.
In digital recording that's equivalent to using less bits, which means 
lower quality.
Say you use 16 bits, but recording is so quiet that you don't use 
the 4 bits that cover the louder ranges. You could end up with what is
effectively a 12 bit recording (as an example).
Boosting volume up to the full range of 16 bits won't get back the lost 
resolution. 

With a 24 bit recording you can afford to lose those 4 bits without any worry.

The quantisation noise that you get with a low bit rate recording is thus
avoided.

Luckily the H2 circuitry has very little hiss when using the internal mics,
so this all works just fine.



 The gain settings are L/M/H. I have it set to M (mid). I've put up the 
 volume control (on the left hand side) to 100.

Exactly. The H setting has just a little bit too much gain when recording a 
Lute,
so the M setting is the only good choice. 

 
 I use an old version of Audacity for editing on the computer. I usually 
 just bring in a wav file and 'normalise' it to 95%. You say 'in editing, 
 boost the levels'. Is that the same as 'normalise'?

Yes, that's it. Normalising is just a level boost that is calculated for you.


hope that helps

Dear David,

Yes, the design is predicated on putting the hole in a solid plastic 
plate over the endpin of the bass, so you only need a secure hook to 
double that function. You also need slightly longer elastic cord to 
attach the straps up to the handle. All fairly straightforward.

[LUTE-BUILDER] Re: Archlute Bridge

2012-06-18 Thread Richard Lees

As usual,
Dana Emery strikes again !

Excellent post ...
excellent post...

Sonically too, Ebony is not the most musical of woods and while I have 
retopped a beautiful archlute for a player out here which had ebony 
staves, one could lightly sense the enharmonic character of ebony in its 
sound... now for bridges,  Dana is right with respect to correct build 
procedures ..But if our mystery bridge turns out to actually be 
ebony ( and I have seen some pretty strange stuff done in our modern era 
with lutes) now would be the best time to replace it

I especially like Dana's suggestion to check all joints !
In the retopping of the archlute I mentioned above MANY braces (well 
over half!) had crystalized glue joints and so I  had to re-brace the 
entire instrument. This instrument which was made by a pretty well 
known luthier was built in the late 70s.
AND if the top is pushing 20 plus years , Dana's additional suggestion 
of simply putting on a new top is indeed called for...

A last note to Dana's post
some years ago i posted a quick observation on cracks, and its worth 
mentioning  it again.

And Dana is yet again right on target
The Spanish masters of lutherie during the mid 60s  many of  whom I had 
the great honor to know , were absolutely firm on this issue.. We are to 
brace perhaps 5 or 6 percent LOW with respect to the expected humidity 
the instrument is going typically see This is to insure the health 
of the top and to make sure the top sounds well too.

BUT there is another monster lurking here..
If the players don't also agressively monitor EXCESSIVE HUMIDITY as when 
when the relative humidity is in excess of say 20  percent of the build 
target, then the wood will expand accordingly ... Now since the 
plantilla or shape of the instrument is fixed by the braces and bowl , 
the softer top, as it expands,  has no where to go...
What happens then is that the wood first bellies upwards and then starts 
to crush itself, under these high humidity conditions and then, when the 
humidity drops , the top can REALLY crack,  and whats worse, at a higher 
level of humidity even than the target build point!
This occurs because by virtue of have been laterally crushed, the top is 
fundamentally NARROWER than before. When the humidity drops and the top 
shrinks even further, these catastrophic failures can occur.
I restored several German harp guitars like this... The back of one of 
them, a Haberman instrument, had shrunk so badly that it lost over1/4 of 
an inch in width relative to plantilla so that when I removed the back 
you could hear the instrument groan as the stresses were relieved and 
the sides started to reconform .
If this is what has happened to Sterling's lute, then i am afraid a new 
top is indeed in order..

On 6/18/2012 3:32 PM, Dana Emery wrote:
First point, much of that which is black on musical instruments is 
dyed maple and not ebony proper.  The wood used for a lute bridge does 
need to stand up to the strings, but need not be as stiff as ebony, 
fruitwood (pear, plum, apple) are recomended from what I recall.
As has been pointed out your enemy is thermal mass.  A replacement 
strategy allows destructive removal.  Working on the naked top will 
allow the other repair you want to do, and in general you can 
rejuvinate all the joints as you wish.
cracks in the top of a lute are troublesome, and likely when an 
instrument travels to a drier climate than that it was built in (er, 
designed for).  A piano top is designed to have a slight but crucial 
arch that keeps all the joints in compression as it dries out.  lute 
tops are flatter than can allow that, and actually cave in in places 
(especially between bridge and rose); rising in others (below bridge).
An entirely new top might not be a bad idea at this point, but you 
seem inexperienced for that, still should you have the resources, it 
might be an opportunity to consider exploring.  You will want to make 
thickness measuring calipers as well as a go-bar deck and perhaps some 
other specialist tools.  The scrape of the present instrument can be 
used for a model.  You might look for a violin maker in your area to 
share a brew or two with and get some informal counseling.

Good luck

   Excellent post ...
   excellent post...
   Sonically too, Ebony is not the most musical of woods and while I have
   retopped a beautiful archlute for a player out here which had ebony
   staves, one could lightly sense the enharmonic character of ebony in
   its sound... now for bridges,  Dana is right with respect to correct
   build procedures ..But if our mystery bridge turns out to actually
   be ebony ( and I have seen some pretty strange stuff done in our modern
   era with lutes) now would be the best time to replace it
   I especially like Dana's suggestion to check all joints !
   In the retopping of the archlute I mentioned above MANY braces (well
   over half!) had crystalized glue joints and so I  had to re-brace the
   entire instrument. This instrument which was made by a pretty well
   known luthier was built in the late 70s.
   AND if the top is pushing 20 plus years , Dana's additional suggestion
   of simply putting on a new top is indeed called for...
   A last note to Dana's post
   some years ago i posted a quick observation on cracks, and its worth
   mentioning  it again.
   And Dana is yet again right on target
   The Spanish masters of lutherie during the mid 60s  many of  whom I had
   the great honor to know , were absolutely firm on this issue.. We are
   to brace perhaps 5 or 6 percent LOW with respect to the expected
   humidity the instrument is going typically see This is to insure
   the health of the top and to make sure the top sounds well too.
   BUT there is another monster lurking here..
   If the players don't also agressively monitor EXCESSIVE HUMIDITY as
   when when the relative humidity is in excess of say 20  percent of the
   build target, then the wood will expand accordingly ... Now since the
   plantilla or shape of the instrument is fixed by the braces and bowl ,
   the softer top, as it expands,  has no where to go...
   What happens then is that the wood first bellies upwards and then
   starts to crush itself, under these high humidity conditions and then,
   when the humidity drops , the top can REALLY crack,  and whats worse,
   at a higher level of humidity even than the target build point!
   This occurs because by virtue of have been laterally crushed, the top
   is fundamentally NARROWER than before. When the humidity drops and the
   top shrinks even further, these catastrophic failures can occur.
   I restored several German harp guitars like this... The back of one of
   them, a Haberman instrument, had shrunk so badly that it lost over1/4
   of an inch in width relative to plantilla so that when I removed the
   back you could hear the instrument groan as the stresses were relieved
   and the sides started to reconform .
   If this is what has happened to Sterling's lute, then i am afraid a new
   top is indeed in order..

First point, much of that which is black on musical instruments is
   dyed maple and not ebony proper.  The wood used for a lute bridge does
   need to stand up to the strings, but need not be as stiff as ebony,
   fruitwood (pear, plum, apple) are recomended from what I recall.
As has been pointed out your enemy is thermal mass.  A replacement
   strategy allows destructive removal.  Working on the naked top will
   allow the other repair you want to do, and in general you can
   rejuvinate all the joints as you wish.
cracks in the top of a lute are troublesome, and likely when an
   instrument travels to a drier climate than that it was built in (er,
   designed for).  A piano top is designed to have a slight but crucial
   arch that keeps all the joints in compression as it dries out.  lute
   tops are flatter than can allow that, and actually cave in in places
   (especially between bridge and rose); rising in others (below bridge).
An entirely new top might not be a bad idea at this point, but you
   seem inexperienced for that, still should you have the resources, it
   might be an opportunity to consider exploring.  You will want to make
   thickness measuring calipers as well as a go-bar deck and perhaps some
   other specialist tools.  The scrape of the present instrument can be
   used for a model.  You might look for a violin maker in your area to
   share a brew or two with and
