	I found an old drum kit soundfont from years ago that I forgot I had. It's extremely well put together. Each drum sound has a dozen or so volume levels with separate samples for left and right channel. I loaded the soundfont into swami, and I can play it just fine with my MIDI keyboard. When I try it with csound and sfplay, it loads fine and runs without any errors, but I get no sound output. Here is the orchestra, and score, and csound output. If anyone has the means to download a 200M soundfont and try it, it can be found here: http://tobiah.org/drums There is also an excellent and very convincing grand piano soundfont there for comparison that you might like to grab. Thanks for any help on getting this killer drum patch to work with csound.

	By the way, I think you should divide by 32768 to normalise the volume, not 32767.

I'm actually working in floats so anywhere in the ballpark is cool. I'll give the fluidsynth a try. I was actually just looking at the docs. I generally look to sfplay first, because I can process each note that way. It seems that with fluidsynth, all I get is a stereo output for everything that's happening in the system. No chance to modulate or analyze individual events. For this drum soundfont however, it would be just fine. Tobiah Send bugs reports to this list.

	Well, 32768 is the correct figure: - 32768/32767 =-1.000030518509476 which is an overflow in a float stream. That's what I meant.

	I agree about the number. I was just extraneously mentioning that the exact number wasn't the first thing on my mind when I wrote that line, because I'm using floating point files and scale at the end. > Well, 32768 is the correct figure: > - 32768/32767 =-1.000030518509476 > which is an overflow in a float stream.

	I'm seeing the same results as Tobiah so far with no sounds. I've got some older projects using fluidsynth that I need to copy some soundfonts from another computer. I'll try with 5.11 when I get those copied and will see if those projects run.
