Subject: PATCH CACHING

Hello,

I am using a GUS together with Wincake as a sequencer.
Patch caching works fine with Wincake for melodic patches.
However, what do I have to do to load a percussion patch (where
each key is assigned to a different instrument) ?

Greetings from
Volker

I too have wondered whether any software could read CD
audio and play it digitally through the GUS without
first saving to disk (rather than just routing the
analog audio from the CD through the GUS).

I'm not sure why one might want to do it, except that it
sounds interesting. I suppose if the software could keep
up, you could implement some real-time filtering on the
data.

The various programs for reading CD audio (I have seen
various ones for DOS, and there is one for Windows bundled
in Corel SCSI II), seem to have difficulty in reading the
data as fast as it should be played. Some of them take
several times longer to record the sample than it takes
to play. From the docs, I guess that this is because the
CD keeps having to be re-positioned between each sector
read, rather than reading the data as a continuous stream
(as I assume they do when just playing in Audio mode).

I don't know if the newer (2x, 3x, 4x) models of drive are
able to utilise the higher speeds when reading audio data -
if they were, then this would leave more spare time for
positioning etc.

I guess this post isn't very 'music' related, but I'm just
following up yesterday's item. I wonder how many subscribers
to gus-music there are - it seems to be nearly dead?
