This section documents known issues with the all versions of Ardour up
|
|
to and including 1.0. It is not a replacement for our
|
|
<ulink url="http://tracker.ardour.org/">bug tracking system</ulink>,
|
|
but instead summarizes some known issues that are likely to be
|
|
encountered by users and are not in the process of being fixed.

ardour's interpretation of "beats per minute" is different from
|
|
most other programs and from convention. 1 "beat" is whatever the
|
|
meter in effect defines. Thus, 120 bpm in a 4/4 meter is 120
|
|
quarter notes per minute; 120 bpm in a 3/8 meter is 120 eighth
|
|
notes per minute.

copying or cut-n-pasting two (or more) regions that have a
|
|
crossfade between them to a new location or a new track does not
|
|
copy the crossfade. Until a future version of Ardour changes this,
|
|
you are advised to do region editing first, and create crossfades
|
|
second.

it is not possible to create pan automation control points using
|
|
the mouse for stereo (or higher channel count) tracks and busses.
|
|
you can create automation for these configurations by recording
|
|
panning motion, and you can edit the data using the mouse.

when importing an audio file directly into a track, there are no
|
|
choices for the quality level of any necessary sample rate
|
|
conversion. On any system that Ardour is running on, there is
|
|
almost certainly a utility called
|
|
<command>sndfile-resample</command> which uses the same sample
|
|
rate conversion library as Ardour. This utility offers a great
|
|
deal of control over the sample rate conversion process, including
|
|
quality levels. Ardour uses the "best" quality internally. If you
|
|
want a different quality, you can use this tool to produce a
|
|
rate-converted file at the correct speed, and then import that
|
|
into Ardour.

when timestretch is used to alter the length of a region, any
|
|
region-specific gain envelope is lost. The new region has the
|
|
default unity gain throughout its duration.

if you overdub on a playlist in an area containing cross-fades,
|
|
the cross-fades will still be audible in spite of the newly
|
|
overdubbed material being "on top" of them. Workaround is to mute
|
|
or remove the crossfades before overdubbing. As a corollary to
|
|
this, creating crossfades that span other crossfades will not work
|
|
correctly in this version of Ardour.
