New Project: Native to LV2 preset converter:
Posted: Thu Dec 12, 2019 2:40 am
Hi @LinuxMusicians!
Here Jofemodo, working on zynthian project.
We (dcoreman, baggypants, mheidt & me) have developed a little tool that can convert presets from native formats to LV2 banks. This is the list of currently supported native formats:
+ DX7 SysEX files (to Dexed LV2 => https://github.com/dcoredump/dexed/tree/native-lv2)
+ OBXD FXB files (to OBXd LV2 => https://github.com/DISTRHO/DISTRHO-Ports)
+ synthV1 (https://synthv1.sourceforge.io/)
+ padthv1 (https://padthv1.sourceforge.io/)
Other formats can be easily implemented, given that you understand enough of the the native format. We tried to make code simple and modular:
https://gitlab.com/Jofemodo/preset2lv2
Also it's available as a pip package:
https://pypi.org/project/preset2lv2/
You know, simply type:
Examples:
Convert a simple DX7 SysEX bank file to a single-bank LV2-bundle. The bundle name is generated from the SysEX file name.:
Convert a directory containing DX7 SysEX bank files to several LV2-bundles. The bundle names are generated from the directory structure and the SysEX file names.:
Convert a directory containing FXB bank files to one single LV2-bundle with several banks inside. The bundle and bank names are generated from the directory structure and the FXB file names.:
Generated LV2-bundles use the "bank" extension, as described in the specs:
http://lv2plug.in/ns/ext/presets/#Bank
I couldn't find any implementation example nor extra information apart the few lines from the specs, so i hope i understand correctly.
We have implemented the LV2 bank extension in the patched jalv version we use for zynthian. Also have integrated the preset2lv2 converter in zynthian's webconf tool, allowing to upload LV2 & native presets to your zynthian using a web browser.
I hope you enjoy it ...
