Call for Surge's LV2-presets

Software
6

I just commited 2 new factory banks for Surge: Monosynth & Bass

For enjoying them, follow the standard procedure:

  • update
  • from webconf->LV2-Plugins, click “Search for new Plugin & Presets” button and wait (it takes a little bit to parse the LV2 world)
  • restart zynthian-UI (or reboot)

I assume that all the presets available initially from the Surge’s GUI are free, as they are included on the github repository, that has GPL3 license. If not, i hope you send me a decent cake. Over 2 years of wyleu’s rook soup is enough for anyone :sweat_smile:

Ahhh! The script:

create_lv2_bundle_bank_surge.sh (1.9 KB)

#!/bin/bash

#------------------------------------------------------------------------------
# Script to generate a LV2-preset-bank from a set of single-preset bundles,
# like those generated by jalv.gtk and others.
#------------------------------------------------------------------------------
# => First parameter:  Bank sufix common to all single-preset bundles. 
#                      For instance, if all preset-bundles have dirnames like 
#                      "Surge_006-Factory_Monosynth_XXX.lv2", you should take 
#                      "006-Factory_Monosynth".
#
# => Second parameter: If specified, it will be used for naming the generated
#                      bank. If not, the first parameter is used.
#------------------------------------------------------------------------------

BANK_NAME=$1

if [ ! -z "$2" ]; then
	BANK_RENAME=$2
else
	BANK_RENAME=$BANK_NAME
