grainstretch~


    Flexible realtime timestretching and pitchshifting with a granular engine in Max/MSP.
    With this external you can expand your max toolkit for natural and experimental playback. It incorporates the algorithm used by Mattijs Kneppers in his granular stretcher patch and adds a load of extra options and features.
    It is available for both windows and mac, and works in max 5 (in 32bit) and max 6 (in 64 bit).
    The video below gives you an impression of what you can do with it by giving you a walkthrough using the helpfile:

      looks like the utlimate ready-to-use pitchshifter/granulator

      hi there,
      great external, love it.
      but, does anyone now a way to be able to select start and end points of a loop (using grainstretch~ for playback), and change them at any time? Would like to be able to do that with waveform~ if poss.?

      excuse me if this is a dense question, but it says it works in max 64bit. however there is no 64bit external included in the zip file and thus max will not recognize the file. can someone clue me in here? thanks!

      How does grainstretch~ work with a microphone?
    • Oct 25 2014 | 10:06 am
      I previously used grainstretch but now I have switched to 64bit it doesn't seem to work (won't load).
      Any tips or alterantives?

      Same problem here, it works when i start the 32bit max but won't load in the 64bit version .. And this is a problem because i want to use it with max for live and this requires max to run in 64bit (because max for live wont open in 32bit with my 64bit version of Live)
      I really want to use it it looks awesome ! Please help :)

      Is there anyway of getting this working with Max 7.1?
    • Mar 20 2016 | 5:00 pm
      Bump... I am on Windows 10, Max 7.2. Neither 32-bit nor 64-bit work. Are there *any* alternatives to this right now?
    • Mar 18 2017 | 3:53 pm
      Same here.
      The closest i could get was to use the time stretch, pitch shifting stuff in groove~. For some reason it crashes often.
      Same problem with all of my 32bit FFTease devices.
      Does Jbridge work for 32bit Max For Live devices on a 64bit Windows 10 system?

      not quite "alternative", but
      does independent pitch v. time stretching quite well, platform/version agnostic (requires gen~).
      I'm sure Timo will respond to your issues; and grainstretch~ is indeed a great external.

      Cool, I'll Check it out.
      By the way, I've been reading the forums for quite a while, but only just became a member. Thanks for all your help over the years.
