When I play with the Plugin “MDA DX10”, I cannot use the “Decay” in the “Envelope”-Tab. This always results in a very short and unusable sound. Is there something wrong with that Plugin? Do you also have the same problem with that Plugin?

I am also experiencing the same issue with the envelope in MDA DX10. However, all instrument presets work fine; they have proper decay times, lasting as long as a second.  
At this point, I’ve given up on chasing the .ttl definitions.

Yes it is broken. Some should probably raise a ticket for that…

I found that `/zynthian/zynthian-plugins/lv2/mod-mda-DX10.lv2/DX10.ttl` is the active configuration file. I can edit it and apply the changes by running `systemctl restart zynthian`. Now, I am exploring how to control the parameters more effectively.

**Edit:** Is the closed Issue #1141 related to this topic? [Issue: Instrument: MDA DX10: Envelope -\> Decay seems broken · Issue #1141 · zynthian/zynthian-issue-tracking · GitHub](https://github.com/zynthian/zynthian-issue-tracking/issues/1141)
