I have had the same error using `The Musicator', which uses the MIDI Mapper,
so I don't think it is specific for winjammer. However, it doesn't happen
very often.

My patch manager works with the new drivers, it came with the 2.06 disk set.
Did you copy the new ultrasnd.ini to your ultrasound directory?

Is there a tool available to check the DRAM on the GUS ? I've been
having some clicks that I can hear when wearing headphones. They
hurt my ear. It is only in the left channel. Does this indicate
anything? Since I'm using the patches that came with the GUS
I assume they were done with good samples, good loop points and
good voice handling routines. I like the GUS a lot but the
clicks I'm getting are terrible. I'm using Power Chords to produce
the music that has the clicks.

Not sure I follow this, but if you're saying: why have real-time synthesis
when you can just have sample playback, the answer is that the sound
modification possible through real time synthesis is a much more efficient
way of allowing tonal variation in synthesised sounds. For example, let's
say you want a piano to sound brighter the higher the key velocity.
In the sample playback only framework you have to sample it several times
at different velocities and switch between them depending on key velocity.
It is not easy to get smooth results like this. Alternatively you can use
two oscillators and vary the relative volume of the two, but you may end
up with nasty phase problems if dealing with two similar waveforms.
With synthesis using real-time filters, you just make the filter cutoff
depend on key velocity. Simple and quite effective. (And no waste of voices).
Then of course there's the dreaded `speed up' effect of the harmonic content
in sample playback only. That is, make a nice sound that goes...
Biiiiiiiooooooooooowwwwwwww. Play it up two octaves and now it only goes
Biioow. This is a very unappealing trait of sample playback. THe only
way around this is to sample many times across the keyboard. (which
uses up lots of memory). On the other hand, if you have filters built into
the machine then they can make the Biiioooooowww out of a simple sawtooth
wave and you won't have any `speed up' problems.
Of course, if software synthesis was fast enough to run in real time none
of this would apply. But then again, you wouldn't need a GUS either.
Chris.
