I am using an ARM board with Ubuntu Linaro 13.04 and Alsa as the sound and MIDI
driver. I have aSF with 13 different instruments and playing through USB MIDI.
As the Fluidsynthstarts I use CC 0 7 0.... command to reduce the volume of all
the MIDI channelsto zero. When a key is pressed the MIDI sends Note ON command
to all 16 MIDI channels. Iswitch ON/OFF instruments by setting the MIDI channel
volume 0 or 127 again by using cc commandagain. My issue is when I start FS, I
get the following warnings,fluidsynth warning: Requested a period size of 64,
got1024 insteadfluidsynth warning: Requested 16 periods, got 8 instead When I
play 4 notes(up to 4 notes) simultaneously itplays perfectly but when I press
the 5th key (or more) there is a crackling sound like abuffer underrun and when
I release one note (4 again) it plays perfectly again. I tried using -c and -z
to change the period size but cannotreduce the period size less than 1024 and
cannot increase number of periods to morethan 8. Any suggestion how this can be
fixed? Regards Herschel
