Dear Forum,

I managed to extract a ppq stream from my DAW using plugdata´s [playhead]:

How to convert to sixteenth note bangs for further synchronized rhythmic application using the Bangs=beats?

One quarter note is divided in 10000 parts. So 47.9999 ist the last part of beat 47 and skips to measure 48 on the next part change.

The quarter notes could be extracted for a pulsating bang with: (ppq value)-[int]-[change]-[bang] so far in a first step.

Thank you!

The problem I found when I tried to use DAW sync messages is that the time values followed audio driver ticks and did not follow integer values in the timeline. I was using [r _playhead] but I think I saw similar behavior from [playhead]. Generating bangs in response to these ticks would be late by some ms.

My approach to this (in an abstraction, playhead-tick, at http://github.com/jamshark70/hjh-abs) was to set a threshold within the beat, like 0.9 or 0.8, and when the incoming time value exceeds the threshold, calculate the time until the next true beat and use this with [delay] to output the bang (or beat number) at exactly the right time.

This handles only beats, not subdivisions, but another abstraction in the same library, [burst], serves as a clock multiplier to get any subdivision you need. Both of these objects use tempo change info from the DAW so the subdivisions will change speed too, if the DAW tempo changes.

You are a magician!

I worked through the video and got it running.

My final aim is to sync Logic Pro X and start out building (hopefully) complete music pieces generated in Pd with a hybrid intend coorporating guitar improvisation, too. Here comes the DAW part into play. Maybe running Pd/[abl-link~] still has an advantage for external synchronisation to a DAW, though. I found you can´t [s xy] [r xy] outside the plugdata plugIn.

btw: I tried [fader~] but got some error message:
canvas: no method for 'delete'
1032-catch 1 0 0 0 (catch~->outlet) connection failed

I also saw some of your performances on YT. Very inspiring! Are the visuals (i.e. Wind and Shadow) made in Pd, too? Thank you!

fader~ depends on the iemguts external pack, should be on deken.

Thanks! Those visuals were made by students, one using jitter, the other using touch designer. (I'm terrible at visuals myself.)

Thank you very much for your help and patches!! I am hesitating a bit to use work of such high degree. Maybe there is a chance to show appreciation in some way, shape or form. Thank you!!
