When I set the parameter for buffer to "-B2,9", everything works fine (but the latency isn't fit for realtime use). In this r10 version anything lower than that causes the output to distort so hard you can't recognize it. I'm using the "FluidR3" soundfont. I witnessed this with jack (jackd started from qjackctl) and direct hardware access via ALSA (using the file /etc/asound.conf). [workaround: downgrade to the r7 version, e.g. block the r10 one in /etc/portage/packages.mask] Reproducible: Always Steps to Reproduce: 1. set the buffer with -B2,8 or below (using an aprotiate output, such as jack or an ALSA "hw" device) 2. try to play music (I connected my keyboard via qjackctl) Actual Results: distortion Expected Results: Fine working software music synthesis with low latency.

If you remove the ${FILESDIR}"/${P}-polling.patch from -r10, it works I assume? Miguel, your patch is about to get removed as it appears to break timidity++.
CLandel, you need to verify this before it can be done. -r7 is now removed from tree.
Sorry for being inactive for so long. How do I compile this without the patch? emerge won't let me when I edit the ebuild. Now with the r7 version removed, we need a fix, or the r7 version back. Has this behaviour been confirmed by anyone else?
Created attachment 198955 [details] Remove polling patch. Same as -r10 without -polling.patch.
Or simply change these, "${FILESDIR}"/${P}-protos.patch \ "${FILESDIR}"/${P}-polling.patch To this, "${FILESDIR}"/${P}-protos.patch In -r10 ebuild and run `ebuild timidity++-2.13.2-r10.ebuild digest` or `emerge --digest timidity++` after it.

The polling patch makes it not wake CPU so often... and I'm suspecting it might not be correct. So it's up to you to verify.
I'm positive, the "polling" patch destroys the sound when the buffer is low. I commented the relevant stuff (the line with the patch and the backslash) out, but I needed the "--digest" option for emerge so I could verify that it would work. After emerging timidity++ with a hacked ebuild and --digest, it now works normally. Of course, I'm leaving this now like that on my system until r11 is out because I need low latency. Thank you for dealing with this.
