As I created many amSynth presets for standalone usage, I needed to convert them to a different standard as I wanted to use them within the LV2 plugin version of amSynth. I converted the first presets by hand, which was a painstaking experience. As I had many more to go, I wondered whether I could automate this process. With trail and error I created a script. It uses a template, copies it and replaces the values from the given preset.
You can download the script and the template here or copy, paste and save the code below, between <script> and </script>:
# Name: amSynthPresetConverter.sh
# Author: Winko Erades van den Berg
# Date: October 23, 2018
# Revised: October 23, 2018
# Purpose: To convert amSynth presets to LV2 preset
# You would need to make this file executable by giving executable
# permissions: eg. chmod +x ./netbook.bash
cp $TEMPLATE $CPTEMPLATE
while read LINE; do
PARAMETER=”<“$(echo $LINE | cut -d ‘ ‘ -f 2)”>”
VALUE=$(echo $LINE | cut -d ‘ ‘ -f 3)
if [[ $VALUE = *”.”* ]]
sed -i “s/$PARAMETER/$VALUE/g” $CPTEMPLATE
sed -i “s/$PARAMETER/$VALUE”.0″/g” $CPTEMPLATE
done < $FILENAME
Don’t forget to change the executable status of the file you just created by typing: sudo chmod +x ./amSynthPresetConverter.sh
It creates a new textfile called: (date and time) amSynthTemplate.txt
You can copy and paste its contents to your amsynth.lv2 folder into your amSynth.bank.ttl.
Dont forget to:
- change your preset name 🙂
- add your presets to amsynth.ttl
