Hi Aere,
Thanks for your reply. I did create a <userID.conf> file earlier but there was
no improvement. I'm not sure whether I re-started the machine. I will do this
again and let you know the how it goes.
I was actually suspecting "Requested 16 periods, got 8 instead" - can this be
the issue?
My arm board is Alwinner A20, 1GHz, 2GB RAM etc., so it should work with these
resources.
Regards
Herschel

Does your ARM processor have a floating point unit (FPU) ? FluidSynth is
heavily floating point based, so if you don't have hardware support for
floating point, it will get pretty poor performance. Check your CPU usage and
see if it is maxing out when you press that 5th key.
Best regards,

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
