hi ...

im trying to get an external working that will encode gates signals from a digital audio stream. this is for controlling synths and drums and other analog modular gear.

its described on this page: http://www.expert-sleepers.co.uk/es5.html

there is already a max version and a pd version that works on mac/win, but sadly i cant get it to work in linux. this is not my code but from andrew from expert sleepers.

i can compile the code with the included makefile without errors. i then installed es5encoder~.pd_linux in my pd-externals folder. do i also need to install main.o somewhere?

i then can instantiate [es5encoder~] but when i run it it crashes pd as soon as it is connected to a dac~. i suspect there is something missing in the makefile.

im including the source and makefile in a zip. can somebody with more experience PLEASE look at the makefile and see if everything important is included. i really have no clue.

any help is greatly appreciated!

nobody is building externals in linux here?

what do i need to include in the makefile if i compile c++ for a pd-external on a linux machine? somebody please point me to some info, i cant find anything about it. is there an example for a makefile somewhere? thanks!

have you tried the template provided here:
http://puredata.info/docs/developer/MakefileTemplate
or more precisely:
https://svn.code.sf.net/p/pure-data/svn/trunk/externals/template/Makefile

let me know if this compiled version of it works for you

also, on my end, i noticed both your version and mine seem to work similarly (neither crash when connected to a dac~) so the problem might be related to something else

thanks miwi ...

yes i tried the makefile but that one is for c not c++ ... your compiled version still crashes my pd-extended. i can connect it to a dac~ abstraction but as soon as i switch on dac it crashes. it works on your linux machine?

maybe the include libraries for pd-extended are different? i did some soldering to my es-3 but i dont see how a fault in the audio interface hardware can crash pure data. its fine otherwise.

very strange!

yeah, it works on my end, or at least I think it does. I would have a better idea if I had one of these expert sleeper modules hooked up to my computer. All I can tell you is that when connected to dac~ and while being fed floats through the first inlet, it makes clicking noises and an especially large click when passing between 127 and 128

thanks miwi, so it must be my linux/pd setup then!

lets compare it to yours, here is mine:

kx studio clean install based on Ubuntu 12.04.3 LTS
kernel linux 3.8.0-32-lowlatency 64 bit
pd-extended version 0.43.4-1~precise, no pd vanilla installed
puredata-dev version 0.43.04 developer env

audio device:
rme fireface 800 via
ffado-dbus-server 2.1.0+svn2470-0
jackd

maybe its

• pd-extended vs. pd-vanilla
• or 64 bit vs. 32
• very possible! the ffado/jack device

the expert sleeper interfaces are really the coolest hardware i know. you can run them from lightpipe or spdif whatever your soundcard provides. you either get control voltages (ES-3) or gates (es-5) or there is a new one with midi/dinsynch all from one audio channel and in audio precision. zero lag!

you need a eurorack panel or some 12 volt power supply for it to install, though.

success! its the "callback" option in the audio settings for pd that causes the crash. without it its fine like wine! thanks miwi for testing this. ill write a short manual for pd and those interfaces soon ...
