Hi,

I have been wondering why is PD's MIDI output so jittery and why it has so many problems with note-offs not working properly (hanging notes every few dozens of notes, with fast sequences even more often).

I have recently tested a simple MIDI out patch in Max 7 and its MIDI output is rock solid no matter what. No hanging notes, no noticeable jitter. It is the major thing that is making me considering purchasing Max 7 but I have also found out, during the testing, that it really crashes a lot while doing basic things so I would stay with PD if the mentioned MIDI output problems are fixable.

Can there be anything done in/with PD that would make MIDI out solid as in Max 7?

I really really want to love PD but this is a major bummer. I really need to output MIDI to a DAW.

Thank you.

on windows i was able to do what i want within ableton / cubase / Reaktor or any program itself...no problems. but i was not really able to build something that works god as an bridge between applications (except rewire). i tried all the midi-stuff to interconnect, but it was not really usable cause i had to setup everything everytime again, and sometimes a midi bridge won't work, or i wasn't able to interface to opensoundcontrol things like touchOSC with some application (especially ableton). but my ultimate goal was to get rid of all the audio cables in my system. laptop to my mastering compressor for example. or other stuff that need a cable. so i needed a solution like jackAudioConnectionKit which can work over network which is great if you put a arm-based oneboard computer in each component of your chain and connect them over network... i hope this wasn't demotivating.

what are you exactly trying to build so that you want to control you DAW externaly vi pd

I simply need to send tight MIDI events and tight control events (FX automations, etc) to a DAW that will record it. I want to jam with algorithms in PD and be assured that it will be recorded exactly as I heard it during a jam. I would also like my DAW to be in sync with PD, but that is a huge problem...

you need to lower your blocksize in the Audio-Settings of PD to the minimum. The Bangs and all control signals in PD are processed with each block of audio.

blocksize = 64
i get ca .+/- 5 ms in the timing on input and output. your ears shoudln't notice this difference in a bad way.

Thank you for the info.

5 ms is quite a lot, in my opinion (as it could create a different feel in music when a lot of tracks is involved, or when transient control is the key).

I still have not tried setting up PD VST but I suppose it should be the tightest way of generating MIDI into a DAW. What you think?

i don't really know. after a few coffes i remembered that the PDvst ist either an instrument or an effect. i don't think its possible as a kind of midi effect.and please believe me, 5ms are really not much. you shouldn't be able to recognize it. the human ear can recognize differences above 25 ms in an not continous signal. i would give it a try.

for example: the minimum attack stage of an envelope in vst plugins ist about 5 ms too, to surpress clicking on unsynced oscillators

and you can always download the trial for maxforlive to check if its better.

ahh...but you can use PDvst as instrument with an similar patch as mine to determine the real timing within your daw.

Unfortunately, I produce a lot and I know for the fact, that 5ms difference is perfectly audible if you deal with sharp transients. If you have two tracks of sounds meant to play together with prominent transients and peaks, 5 ms drifting would create a huge sonic difference.

I will try the PDvst and see how stable and usable it is. I just can't bring myself to install and set it up properly, yet.

in addition to the one time per block processing of messages, incoming and outgoing messages are delayed by on block each time they pass the borders of PD to the world
