OctaHack/OTRP: tempo dependent sample repitching (MMP/Pd, lemur)

Update 29 September 2014

OctahackOTRP MMP v3 - Now idiot-proof !!!

  • Played live using the patch on Saturday; this compelled me to make the tempo input buttons bigger.

  • looper and encoder remapping have been omitted in this version. The up side: You only need one MIDI cable now, and no setup on the OT.

Find the latest version (HoToolzOTRPv3_MMP.zip) here:

EDIT 18 MAR 2015: broken link removed, will repost asap.

Update 23 September 2014

Octahack MMP v2

-now uses the same, improved repitch algorithm as the lemur version
-no longer tracks MIDI clock; you enter master tempo manually*

  • the old version is still available.

*i will happily discuss this change in detail with anyone interested when i get the time.

HoToolz Update 27 July 2014

OTRP for lemur – improved master tempo tracking and sample repitching.

  • Improved repitch: The previous, approximative algorithms used in the MMP/Pd patch (OctaHack_v101) have been replaced with an expression that is precise within the constraints given by the MIDI standard and OT’s pitch parameter scaling. (max. deviation: +/- 0.1 semitones)

  • Improved clock tracking: the lemur version relies on the internal clock_ functions, which significantly improve tracking speed and stability, compared to the current MMP/Pd version.

  • Easy setup (no “clock notes” in OT required).

INSTRUCTIONS

  • Lemur patch download - here: http://hotoolz.tk (HoToolzOTRPv1.jzml)

  • Connect OT MIDI in/out to an iOS lemur instance of OTRP via MIDI interface.

  • Within lemur, enter the original tempo of the samples playing on OT audio track 1 (faders on the left) and track 5 (faders on the right).

  • Important: Set Octatrack MIDI AutoChannel to: Off.

NOTES

  • Encoder remapping and one-touch looping (present in the Pd/MMP patch) have been omitted in this lemur version. Minimal layout suitable for most screen sizes.

  • Pd/MMP patch revision/update coming soon. The current one is still available for download.

Feel free to post questions or suggestions in this thread.

Thanks, Michal!

This is probably a stupid question but… will this work with the hardware Lemur or is it only for the iOS app?

#6

Good question. It should work with the hardware version as well (it only uses “oldschool” objects), but i only tested on iOS.

#7

I was wondering whether templates designed for the Liine iOS Lemur could be loaded by the Jazz Mutant hardware Lemur. I’m pretty sure they can’t though.

I was given a Lemur shortly after I bought my Octatrack, 6 months ago, and I’m just about ready to start trying to integrate it.

#8

Open the template in the editor and save it in legacy mode.

#9

i have added a legacy template. (HoToolzOTRP_v1-LEGACY.jzml)
you can get it from the hotoolz.tk downloads folder.
let me know if you can open it on your lemur hardware.

#10

Great, thanks! I plan to get it out of the box later today - I’ll let you know how I get on.
