Raspbian buster and ubuntu bionic arm (32 & 64bit) builds of vcvrack v1.1.6

hello and happy new year to all of you,

there is a new arm build of vcvrack out for raspbian buster and ubuntu bionic arm (32 & 64bit) based on vcvrack v1.1.6.

it can be found here: https://github.com/hexdump0815/vcvrack-dockerbuild-v1/releases

more information about it can be found here: https://github.com/hexdump0815/vcvrack-dockerbuild-v1

and specifically for runing it on the raspberry pi here: https://github.com/hexdump0815/vcvrack-dockerbuild-v1/blob/master/readme-raspbian.txt

changelog for version 1.1.6

  • upgraded vcvrack to version v1.1.6
  • reverted framerate management (VCVRack/Rack@e631131) as it resulted in increased cpu usage in iconified mode on arm systems with mali gpu - still to be analyzed why …
  • reworked plugin building now based on the library repo
  • most plugins are now built with “-mfpu=neon” on armv7l and for raspbian too with a few exceptions (they result in a SIGBUS crash of vcvrack due to unaligned access if compiled with “-mfpu=neon”)
  • 113 open source plugins included resulting in 1300+ vcvrack modules!

i’ll work on preparing a new sonaremin (https://github.com/hexdump0815/sonaremin) release based on this build and a few other ideas i have for it during the next weeks, so stay tuned …

best wishes - hexdump

If VCV provided an official ARM build of Rack, would ARM64 Linux be all that’s needed?

hi andrew,

i think both armv7 (32bit) and arm64 (64bit) would be required, as the main target right now would be raspbian on the raspberry pi i guess, which is still 32bit but the future is clearly arm64 (there is now even a 64bit kernel possible for the raspberry pi and most other arm devices are arm64 nowadays). but right now the resonance to my arm build is quite low, so maybe better focus on bringing vcvrack forward in general instead of spending time with an official arm build right now - i’ll keep doing those arm builds from time to time for whoever is interested as some kind of proof of concept, so that the option is there to move to arm if needed. i think the interest might grow with v2 and the headless option maybe.

best wishes and keep up this cool project - hexdump
