Re: [LAD] liquidsfz-0.2.0
Yes, I understand your explanation. For the moment, I just forward jack received CCs to the lib. I will try to make some mokcup before to update the UI.

Re: [LAD] liquidsfz-0.2.0
Wonderful! I will update QLiquidSFZ then, to reflect the additions you made. Many thanks for this cool library.

[LAD] liquidsfz-0.2.0
liquidsfz-0.2.0 has been released The main goal of liquidsfz is to provide an SFZ sampler implementation library that is easy to integrate into other projects. A standalone jack client and a LV2 plugin is also available. liquidsfz is implemented in C++ and licensed under the GNU LGPL version 2.1 or later. The release tarball can be downloaded here: https://github.com/swesterfeld/liquidsfz#releases Overview of Changes in liquidsfz-0.2.0: --- * Provide LV2 plugin * Support for // sections * Handle #define * Lots of new opcodes supported, including - key switches - crossfading for layers - more amp-related opcodes - allow changing more parameters using CCs * API additions - load progress function (Synth::set_progress_function) - global gain factor (Synth::set_gain) - provide list of CCs supported by .sfz file (Synth::list_ccs) - support pitch bend (Synth::add_event_pitch_bend) -- Stefan Westerfeld, http://space.twc.de/~stefan ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org https://lists.linuxaudio.org/listinfo/linux-audio-dev
