Re: [PD] groove machine how to: keep metro and a loop in sync
Just an update: I solved my issue by removing an [i] object that I inserted in the subpatch that handles the bpm conversion it rounded off the tempo just enough to cause that drift- why I included this in the first place I don't know -.- Now it's rock solid!

So the equivalent for the argument `1' for [phasor~] would be `1000' (milliseconds) for [line~]. Translation is done using the following function: y = 1000 / x, where x is the length of the time interval in ms and y the frequency in Hz (note that x = 1000 / y).

Re: [PD] groove machine how to: keep metro and a loop in sync
Hi Filippo, On Fri, Jan 10, 2014 at 6:57 PM, Filippo Beck Peccoz m...@fbpsound.comwrote: Inspired by a talk on groove by Victor Wooten, I'm working on a patch that plays a wav loop repeatedly (drums) and then cuts the volume on the track for a certain number of beats. The interval gets larger and larger, forcing you to work on your timing and general groove feel. The patch is already working quite OK, but one thing I cannot seem to get completely right is a perfect sync between the beats which cut off the volume of the wav. I'm using a metro object set to the bpm of the loop and start both concurrently. Maybe this is just much too imprecise for what I'm trying to do.. If I understand you right you would like to synchronize an audio loop with a [metro]. I guess you control the audio loop by something like [phasor~] or at least anything controlled within the DSP domain. Then, if you replace such [phasor~] with a [line~], controlled within the event domain there should be no problem anymore. Example: [phasor~ 1] gets [metro 1000] | [0, 1 1000( | [line~] or even something like te following (unpack and pack the message to add something to the second value) [metro 250] | \ | [i ]/[+1]/[%4] | / |/ [0, 1 250( | / [+ ] | [/ 4] | [line~] to divide this second into four line segments.

Dear list, happy new year first of all :) I wanted to ask you about something that should be simple, but might not be that much. Inspired by a talk on groove by Victor Wooten, I'm working on a patch that plays a wav loop repeatedly (drums) and then cuts the volume on the track for a certain number of beats. The interval gets larger and larger, forcing you to work on your timing and general groove feel.
