@etXzat Yes Ubuntu has some quirks when it comes to installing some packages, that is why I build from source and installed in manually.
I want to avoid installing from the official repository since they have outdated versions, see: https://launchpad.net/ubuntu/+source/faust
latest current stable is 2.41
@sletz
make all && sudo make install solved my issues! Thank you very much.
HISE can't load soundfonts. It can load flac and probably aiff but generally it's best to stick to .wav and then convert them to .ch within HISE. It can also import the mapping data from SFZs.
@d-healey hmmmm. not going well. Firstly velocity is optional in my project. Secondly with an arp it continues playing, and thirdly even in a button it doesn't reliably call the waveform... at least not in this project
