Hi, Ben
Thanks for your feedback.
>I'm wondering if there is some multiplier in the patch which is an order of magnitude too large?
No, the patch uses only the following formula based on CC MSB, LSB (in ms).
The patch handle CC portamento time CC 5d (MSB) + CC 37d (LSB) in ms
time(ms) = 128 x MSB + LSB
MSB,MSB value are 0 to 127 each
Maximum time: 128 x 127 + 127 = 16,383 second
> What is it supposed to do? CC5 at 127 gives how much portamento time??
According to the above formula, time will be 16,256 second, near the maximum time, a very long time !
The resolution of CC 5 is 128 ms
CC 5: 1, time = 128 ms
CC 5: 2, time = 256 ms
CC 5: 3, time = 384 ms
CC 5: 4, time = 512 ms
To get smaller time ( < 128 ms) we need to set CC 5 at 0 (which is the default value at fluidsynth initialization), and
use only CC 37d
Notes
(1) CC Portamento 65d must be on
(2) If portamento time is 0 the pitch sweep is not perceptible.(At fluidsynth initialization: portamento time is 0).
(3) If pitch bend is send, it is actually understood by FluidSynth as pitch bend (i.e adding pitch shift .This a default behavior).
That means, that Pitch bend can be used during a portamento effect.

> I haven't tried all the features yet, but the legato and portamento work. The portamento time seems problematic however. I configured the pitch-bend up control on the EWI to give portamento time, and I found that I had to have the gain on the control very low (1 out of 127) to get portamento times of around 1/2 second (note that this is the instrument GAIN, not the actual values sent) . This is much longer than what I experience using a Roland synth. I'm wondering if there is some multiplier in the patch which is an order of magnitude too large? I don't know what numbers the control is sending, but I will investigate further.
