[PD] stability of PD on Windows?

Hi Scott,

Are you using ASIO drivers?

If not you can try this setting which normally works on most soundcards:

1) Switch off DSP.

2) go to menu: media/ASIO(via port audio)

3) set Delay(msec): 6ms

4) set Block size : 256

5) On the i/o devices pull-down menu select your "ASIO:<soundcard name>"

If you soundcard don't provide an ASIO driver (as is the case with most built-in sound cards) use the http://www.asio4all.org/ ASIO driver.

If your soundcard has ASIO driver find its settings and change the  "Buffer size" to 256 samples.

If you are running a very DSP consuming patch try increasing 3) and also 4).

hey folks - i've been working with PD using a Windows 10 laptop and i seem to be having a difficult time keeping the setup stable and getting low latency audio out.

i have used this Windows 10 laptop for a variety of tasks with VR rigs, gaming, browsing,etc and it does a credible job, but running PD 0.49 i have experienced a wide variety of inconsistent behavior.

mainly it's things like USB ports timing out for audio and/or MIDI input, as well as too much latency for instrument playback (20 ms or so, not horrific, but not responsive enough for fast playing. ). i've used 3 interfaces - the onboard audio, a C-Media USB compliant dongle interface, and an Apogee Duet. in all three cases the audio output and MIDI input can randomly time out and stop working - it's usually both at the same time. turning audio off and on can fix the issue usually, but not always.

as far as the latency, it seems consistent at about 20 ms using 32 msec buffer settings. any smaller and it results in buffer distortion on the audio stream.

so i'm just curious if anyone here uses PD on Windows in a live performance capacity (especially as an instrument responding to note or pad input) and if so what setup has produced the most reliability? i have actually tried this on a Mac - or to be more accurate, a half completed macOS hackbook on the same machine, and while latency is shorter, the timeout issue is much more severe and cannot usually be fixed by turning audio off and on. for now i'm ignoring using macOS and seeing if i can get the Windows version to be stable, but it would be nice if there were others using it in Windows and getting stable performance. maybe there's extra tweaks available in Windows that help the stability? let me know what works for you!
